Detailed Description

An object used to modify a DTS or COLLADA shape model after it has been loaded by Torque.

TSShapeConstructor is a special object used to modify a DTS or COLLADA shape model after it has been loaded by Torque, but before it is used by any other object.

It is often used to share animations from DSQ files between shapes with a common skeleton.

It may also be used to 'Torquify' a model that is missing the nodes and/or sequences required to function as a particular Torque object. A model used for a Player character for example should have an eye and a cam node, but these might not be present in a model not specifically created for Torque. TSShapeConstructor allows the missing nodes to be added and positioned so that the shape does not need to be re-worked or re-exported by an artist.

Note:
In T3D, TSShapeConstructor is no longer a SimDataBlock (like in TGE and TGEA), but a SimObject instead. This means that all declarations of TSShapeConstructor should use the singleton keyword instead of the datablock keyword.

TSShapeConstructor also includes features to aid in loading COLLADA models, such as allowing the <up_axis> and <unit> elements to be overridden, and can also apply a user specified prefix to the names of COLLADA materials as shown below. Prefixing material names is useful to avoid name clashes, particularly for 3D apps like Google SketchUp that export models with generic material names like "material0". These options are most easily accessed using the COLLADA import gui, which will be displayed automatically the first time a COLLADA model is imported into Torque.

collada_import.png

Settings from the import gui are automatically saved to a TSShapeConstructor script in the same folder as the model.

To create your own TSShapeConstructor object, simply create a TorqueScript file in the same folder as your DTS or COLLADA model, with the same filename but .cs extension. For example, if your model file was called myShape.dts, you would create a file called myShape.cs. Some example appear below:

singleton TSShapeConstructor( MyShapeDae )
{
   baseShape = "./myShape.dae";
   upAxis = "DEFAULT";          // use <up_axis> defined in myShape.dae
   unit = "1.0";                // override <unit> to be 1.0
   matNamePrefix = "";          // no prefix applied to collada materials
};

singleton TSShapeConstructor( MyShape2Dae )
{
   baseShape = "./myShape2.dae";
   upAxis = "Y_AXIS";           // override <up_axis> to be Y_AXIS
   unit = -1;                   // use <unit> defined in myShape2.dae
   matNamePrefix = "myShape2_"; // prefix all collada material names with "myShape2_"
}

The name of the TSShapeConstructor object (MyShapeDae and MyShape2Dae in the code samples above) is up to you, but you should choose a name that does not conflict with other objects or datablocks. A common convention for TSShapeConstructor objects is the name of the shape file. eg. MyShapeDae for a file called myshape.dae.

When Torque loads a DTS (.dts) or COLLADA (.dae) file, it first looks in the same folder for a TorqueScript file with the same filename (but .cs extension) in order to create the TSShapeConstructor object. Such scripts are executed automatically by Torque 3D, so there is no need to manually call exec("myShape.cs") from another script. Also, you should avoid adding other object and datablock declarations to this script because it will be executed every time the model is loaded, which may cause unexpected results if the datablocks already exist.

After Torque has loaded the model from the DTS or COLLADA file, it executes the TSShapeConstructor onLoad method to apply the desired set of changes to the shape. It should be noted that the changes are applied to the loaded model in memory rather than to the DTS or COLLADA file itself. This means the model can be re-exported to DTS or COLLADA without overwriting the TSShapeConstructor changes. TSShapeConstructor should be thought of as a post-export processing step, and is intended to be used alongside existing object and datablock setups.

Note that DSQ sequences may still be specified within the TSShapeConstructor object as normal:

singleton TSShapeConstructor( PlayerDts )
{
   baseShape = "./player.dts";
   sequence = "~/art/shapes/actors/animations/player_root.dsq root";
   sequence = "~/art/shapes/actors/animations/player_forward.dsq run";
};

function PlayerDts::onLoad( %this )
{
   %this.addCollisionDetail( -1, "box", "bounds" ); // collision mesh
   %this.addSequence( "walk", "walk_short", 1, 5 ); // add subsequence
   %this.addTrigger( "walk_short", 3, 4 );          // add trigger to sequence
   %this.renameSequence( "walk", "walk_long" );     // rename sequence
   %this.renameNode( "Bip Pelvis", "pelvis" );      // rename node
   %this.addNode( "mount5", "Bip L Hand" );         // add a new node
   %this.dumpShape();                               // dump shape to console
}

Note that most of the features in TSShapeConstructor are far more easily accessible in the Shape Editor tool. This tool uses TSShapeConstructor 'under-the-hood' to edit the nodes, sequences and details of a shape, and the changes are saved to a TSShapeConstructor script object.

Shape Terminology

The following definitions should be understood before reading the TSShapeConstructor examples and function reference:

node
A node is a place-holder for transform (position and rotation) information. Nodes are arranged in a parent/child hierarchy allowing complex skeleton structures to be built up.
sequence
A sequence is a set of keyframed node transforms and object states (eg. visibility).
detail level
Level-of-Detail (LOD) is very important to maintain good rendering performance. When a shape is rendered, Torque automatically picks a single detail level based on that shape's on-screen size. Only the sub-meshes belonging to that detail level are rendered.
object
An object is a collection of meshes, each at a different detail level. Each object is attached to a certain node, and is rendered at that node's current transform.
mesh
A mesh is a piece of geometry, and may be a rigid body or a skin (vertex weighted mesh). Each mesh is associated with an object and a certain detail level.

Example 1: Adding a Collision Mesh To an Existing Shape

Imagine you have a model that you want to add to the scene as a StaticShape, but it is missing a collision mesh. TSShapeConstructor makes it simple to modify an existing DTS shape to add a collision (or line-of-sight collision) detail level.

First, define the StaticShapeData datablock as normal. Create a script called myShape.cs in the art/datablocks folder, and define the datablock:

datablock StaticShapeData( MyShapeData )
{
   category = "Misc";
   shapeFile = "art/shapes/myShape/myShape.dts";
};

We need to tell Torque to execute this script so add exec("./myShape.cs"); to art/datablocks/datablockExec.cs.

Now we define the TSShapeConstructor object by creating a new script called myShape.cs in the art/shapes/myShape folder:

singleton TSShapeConstructor( MyShapeDts )
{
   baseShape = "~/art/shapes/myShape/myShape.dts";
};

function MyShapeDts::onLoad( %this )
{
   %this.addCollisionDetail( -1, "box", "bounds" );
}

This script will add a box mesh with the same center and dimensions as the original model using the "Col" detail level at size -1. The negative detail size means that the mesh will not be rendered in-game, and the use of the special "Col" name means that this mesh will be detected as a collision mesh by the Torque engine.

When a Torque mission is started, the following steps occur:

  1. On the server, Torque executes art/datablocks/datablockExec.cs, which in turn executes art/datablocks/myShape.cs
  2. Executing art/datablocks/myShape.cs causes the MyShapeData datablock to attempt to load the DTS file
  3. Before loading the DTS file, Torque executes art/shapes/myShape/myShape.cs, which creates the TSShapeConstructor object
  4. After loading the DTS file, Torque executes MyShapeDts::onLoad, which adds the collision detail level to the shape
  5. The StaticShape object can now be added to the scene (it will appear in the world editor (in the "Misc" category under the Library/Scripted tab)

Example 2: Adding a Mesh From an Existing DTS File

The image below shows a boulder.dts shape in the Torque Show Tool Pro (TSTPro). The circled items indicate the geometry and material that will be copied into a different shape using TSShapeConstructor.

tsshapeconstructor_sample.jpg

The following shows how to include the boulder1 mesh in another shape:

singleton TSShapeConstructor( TestShapeDts )
{
   baseShape = "~/art/shapes/rocks/rock1.dts";
};

function TestShapeDts::onLoad( %this )
{
   %this.addMesh( "test128", "~/art/shapes/rocks/boulder.dts", "boulder1" );
   %this.dumpShape();
}

The output of the dumpShape command is shown below:

Shape Hierarchy:

   Details:
      detail128, Subtree 0, objectDetail 0, size 128
      detail2, Subtree 0, objectDetail 1, size 2
      collision-1, Subtree 0, objectDetail 2, size -1

   Subtrees:
      Subtree 0
         Rock2 --> Object Rock with following details:  2
               --> Object test with following details:  128
         col-1 --> Object col with following details:  -1

   Sequences:

   %Material list:
   material #0: 'rock2'.
   material #1: 'MossyRock02'.

Note that the new detail ("detail128"), object ("test") and material ("MossyRock02") have been added to the normal rock1.dts shape.

Example 3: Auto-loading animations

Instead of manually specifying all of the animations to load, it's easy to write some TorqueScript that will scan a folder for any matching animations and add them to the shape automatically. Imagine that we have the following shape (DTS) and sequence (DSQ) files:

The following script will scan the animations folder and add the sequences to the shape.

singleton TSShapeConstructor( ForgeSoldierDts )
{
   baseShape = "~/art/shapes/actors/ForgeSoldier/ForgeSolder.dts";
};

function ForgeSoldierDts::onLoad( %this )
{
   AddAnimations( %this );
}

function AddAnimations( %shape )
{
   // Scan for all player_*.dsq files and add the animations to the shape.
   // Sequence names are taken from the base name of the dsq file. eg.
   // player_run.dsq would add a sequence called 'run'.

   %filePatterns = "art/shapes/actors/animations/player_*.dsq";
   %fullPath = findFirstFileMultiExpr( %filePatterns );
   while ( %fullPath !$= "" )
   {
      // add this animation to the shape
      %fullPath = makeRelativePath( %fullPath, getMainDotCSDir() );
      %seq_name = strreplace( filebase( %fullPath ), "player_", "" );
      %shape.addSequence( %fullpath, %seq_name );
      %fullPath = findNextFileMultiExpr( %filePatterns );
   }
}

Example 4: Splitting COLLADA animations

Many COLLADA exporters do not support the <animation_clip> element, meaning that animated models imported into Torque appear to have only a single sequence containing all of the animations. TSShapeConstructor can be used to split this combined animation into individual sequences. This is most easily done using the Shape Editor tool, but can also be done manually as follows:

singleton TSShapeConstructor( PlayerModelDts )
{
   baseShape = "~/art/shapes/collada/myPlayer.dae";
};

function PlayerModelDts::onLoad( %this )
{
   // Split animations from combined "ambient" sequence
   %this.addSequence( "ambient", "root", 0, 15 );
   %this.addSequence( "ambient", "run", 16, 40 );
   %this.addSequence( "ambient", "back", 41, 55 );
   %this.addSequence( "ambient", "side", 56, 70 );
   %this.addSequence( "ambient", "death0", 80, 120 );

   // Remove combined "ambient" sequence => we don't need it anymore
   %this.removeSequence( "ambient" );
}

Example 5: LOD using separate files

In the past, using LOD required the artist to export all detail levels into a single DTS file. Using TSShapeConstructor, we can combine separate model files together. In fact, we can even use the folder-scanning approach from Example 3 to automatically construct the shape detail levels using all of the model files in the folder!

Note that the detail level models must contain the same object name, and for skinned models, the skin must be applied to the same skeleton for this script to work.

Imagine that we have the following shape (DAE) files:

singleton TSShapeConstructor( SoldierDae )
{
   baseShape = "~/art/shapes/actors/soldier.dae";
};

function SoldierDae::onLoad( %this )
{
   %objName = %this.getObjectName( 0 );
   AddDetails( %this, %objName );
}

// Scan for all DAE files in the folder with the same base name, and add the
// skinned mesh from that file to the input shape. The size of the detail level
// is taken from the end of the filename. eg. soldier_30.dae will add detail
// level 30 to the shape.
// Note that this function can be in a different script so it can be shared by
// multiple TSShapeConstructor objects...
function AddDetails( %shape, %objName )
{
   // Determine the base name of the input file. eg. the basename of
   // soldier.dae is 'soldier'.
   %inputBase = fileBase( %shape.baseShape );

   %filePatterns = filePath( %shape.baseShape ) @ "/" @ %inputBase @ "_*.dae";
   %fullPath = findFirstFileMultiExpr( %filePatterns );
   while (%fullPath !$= "")
   {
      %fullPath = makeRelativePath( %fullPath, getMainDotCSDir() );

      // Determine the detail size, then add the new mesh (assumes exported with size = 2)
      %size = strreplace( fileBase( %fullPath ), %inputBase @ "_", "" );
      %shape.addMesh( %objName SPC %size, %fullPath, %objName SPC "2" );

      %fullPath = findNextFileMultiExpr( %filePatterns );
   }
}

Example 6: Add lights to the scene

Although most often used to modify a shape before it is used, TSShapeConstructor can also be used as a general purpose interface to a 3D shape. For example, a 3D modeling package could be used to layout positions for lights in the scene. On import, the shape hierarchy might look like this:

base01
 +-start01
   +-Lights
     +-lightA
     +-lightB
     +-lightC
     ...

The following code demonstrates how to create a TSShapeConstructor object on-demand in order to access the 3D shape data. This example adds lights to the current scene at position of the lightX nodes in the shape:

function AddLights( %obj )
{
   // Get a TSShapeConstructor for this object (use the ShapeEditor
   // utility functions to create one if it does not already exist).
   %shapePath = ShapeEditor.getObjectShapeFile( %obj );
   %shape = ShapeEditor.findConstructor( %shapePath );
   if ( !isObject( %shape ) )
      %shape = ShapeEditor.createConstructor( %shapePath );
   if ( !isObject( %shape ) )
   {
      echo( "Failed to create TSShapeConstructor for " @ %obj.getId() );
      return;
   }

   %objTransform = %obj.getTransform();

   %lightsGroup = "Lights";
   %count = %shape.getNodeChildCount( %lightsGroup );
   for ( %i = 0; %i < %count; %i++ )
   {
      // get node transform in object space, then transform to world space
      %child = %shape.getNodeChildName( %lightsGroup, %i );
      %txfm = %shape.getNodeTransform( %child, true );
      %txfm = MatrixMultiply( %objTransform, %txfm );

      // create a new light at the object node
      %light = new PointLight() {
         position = getWords( %txfm, 0, 2 );
         rotation = getWords( %txfm, 3, 6 );
      };  
      MissionGroup.add( %light );
   }  
}

The original shape can be placed anywhere in the scene, then AddLights is called to create and place a PointLight at each node.

Example 7: Rigid-body Player Character

Using the addNode and addMesh functions, it is possible to create a rigid-body (ie. non-skinned) player model compatible with the default animations, completely from TorqueScript!

The default player skeleton node transforms were obtained by adding the following code to the TSShapeConstructor onLoad function for a shape that already contained the default skeleton:

%count = %this.getNodeCount();
for ( %i = 0; %i < %count; %i++ )
{
   %name = %this.getNodeName( %i );
   echo( "%shape.addNode(\"" @ %name @ "\", \"" @ %this.getNodeParentName( %name ) @ "\", \"" @
         %this.getNodeTransform( %name ) @ "\");" );
}

The contents of the console can then be copied and pasted into a new script. The script below shows the player model creation process: first pick a dummy dts file (rock1.dts in this case), and delete its existing nodes and meshes. Then create the default player skeleton. Finally, some box meshes are added at certain nodes to build up a rigid-body player character.

// Create the default Torque skeleton (compatible with the default player animations)
function CreateDefaultSkeleton( %shape )
{
   %shape.addNode( "Bip01 Pelvis",      "",                  "-8.10647e-005 8.34974e-006 1.28118 0.00147092 0.999914 0.000312013 1.50833" );
   %shape.addNode( "Bip01 Spine",       "Bip01 Pelvis",      "0.117738 -0.000117005 0.00695224 0.995531 0 0.054662 0.178899" );

bool TSShapeConstructor::addCollisionDetail ( int  size,
string  type,

float  concavity = 30,
int  maxVerts = 32,
float  boxMaxError = 0,
float  sphereMaxError = 0,
float  capsuleMaxError = 0 
)

Autofit a mesh primitive or set of convex hulls to the shape geometry. Hulls may optionally be converted to boxes, spheres and/or capsules based on their volume.

Parameters:
size size for this detail level
type one of: box, sphere, capsule, 10-dop x, 10-dop y, 10-dop z, 18-dop, 26-dop, convex hulls. See the Shape Editor documentation for more details about these types.
target geometry to fit collision mesh(es) to; either "bounds" (for the whole shape), or the name of an object in the shape
depth maximum split recursion depth (hulls only)
merge volume % threshold used to merge hulls together (hulls only)
concavity volume % threshold used to detect concavity (hulls only)
maxVerts maximum number of vertices per hull (hulls only)
boxMaxError max % volume difference for a hull to be converted to a box (hulls only)
sphereMaxError max % volume difference for a hull to be converted to a sphere (hulls only)
capsuleMaxError max % volume difference for a hull to be converted to a capsule (hulls only)
Returns:
true if successful, false otherwise
Example:
%this.addCollisionDetail( -1, "box", "bounds" );
%this.addCollisionDetail( -1, "convex hulls", "bounds", 4, 30, 30, 32, 0, 0, 0 );

int TSShapeConstructor::addImposter ( int  size,
int  equatorSteps,
int  polarSteps,
int  dl,
int  dim,
bool  includePoles,
float  polarAngle 
)

Add (or edit) an imposter detail level to the shape.

If the shape already contains an imposter detail level, this command will simply change the imposter settings

Parameters:
size size of the imposter detail level
equatorSteps defines the number of snapshots to take around the equator. Imagine the object being rotated around the vertical axis, then a snapshot taken at regularly spaced intervals.
polarSteps defines the number of snapshots taken between the poles (top and bottom), at each equator step. eg. At each equator snapshot, snapshots are taken at regular intervals between the poles.
dl the detail level to use when generating the snapshots. Note that this is an array index rather than a detail size. So if an object has detail sizes of: 200, 150, and 40, then setting dl to 1 will generate the snapshots using detail size 150.
dim defines the size of the imposter images in pixels. The larger the number, the more detailed the billboard will be.
includePoles flag indicating whether to include the "pole" snapshots. ie. the views from the top and bottom of the object.
polar_angle if pole snapshots are active (includePoles is true), this parameter defines the camera angle (in degrees) within which to render the pole snapshot. eg. if polar_angle is set to 25 degrees, then the snapshot taken at the pole (looking directly down or up at the object) will be rendered when the camera is within 25 degrees of the pole.
Returns:
true if successful, false otherwise
Example:
%this.addImposter( 2, 4, 0, 0, 64, false, 0 );
%this.addImposter( 2, 4, 2, 0, 64, true, 10 );   // this command would edit the existing imposter detail level
bool TSShapeConstructor::addMesh ( string  meshName,

Any materials required by the source mesh are also copied into this shape.

Parameters:
meshName full name (object name + detail size) of the new mesh. If no detail size is present at the end of the name, a value of 2 is used.
An underscore before the number at the end of the name will be interpreted as a negative sign. eg. "MyMesh_4" will be interpreted as "MyMesh-4".
srcShape name of a shape file (DTS or DAE) that contains the mesh

txfm (optional) transform string of the form: "pos.x pos.y pos.z rot.x rot.y rot.z rot.angle"
isworld (optional) flag to set the local-to-parent or the global transform. If false, or not specified, the position and orientation are treated as relative to the node's parent.
Returns:
true if successful, false otherwise
Example:
%this.addNode( "Nose", "Bip01 Head", "0 2 2 0 0 1 0" );
%this.addNode( "myRoot", "", "0 0 4 0 0 1 1.57" );
%this.addNode( "Nodes", "Bip01 Head", "0 2 0 0 0 1 0", true );
bool TSShapeConstructor::addPrimitive ( string  meshName,
string  type,
string  params,
TransformF  txfm,
string  nodeName 
)

Add a new mesh primitive to the shape.

Parameters:
meshName full name (object name + detail size) of the new mesh. If no detail size is present at the end of the name, a value of 2 is used.
An underscore before the number at the end of the name will be interpreted as a negative sign. eg. "MyMesh_4" will be interpreted as "MyMesh-4".
type one of: "box", "sphere", "capsule"
params mesh primitive parameters:

  • for box: "size_x size_y size_z"
  • for sphere: "radius"
  • for capsule: "height radius"
txfm local transform offset from the node for this mesh
nodeName name of the node to attach the new mesh to (will change the object's node if adding a new mesh to an existing object)
Returns:
true if successful, false otherwise
Example:
%this.addMesh( "Box4", "box", "2 4 2", "0 2 0 0 0 1 0", "eye" );
%this.addMesh( "Sphere256", "sphere", "2", "0 0 0 0 0 1 0", "root" );
%this.addMesh( "MyCapsule-1", "capsule", "2 5", "0 0 2 0 0 1 0", "base01" );
bool TSShapeConstructor::addSequence ( string  source,
string  name,
int  start = 0,
int  end = -1 
)

Add a new sequence to the shape.

Parameters:
source the name of an existing sequence, or the name of a DTS or DAE shape or DSQ sequence file. When the shape file contains more than one sequence, the desired sequence can be specified by appending the name to the end of the shape file. eg. "myShape.dts run" would select the "run" sequence from the "myShape.dts" file.
name name of the new sequence
start (optional) first frame to copy. Defaults to 0, the first frame in the sequence.
end (optional) last frame to copy. Defaults to -1, the last frame in the sequence.
Returns:
true if successful, false otherwise

bool TSShapeConstructor::adjustCenter

Translate COLLADA model on import so the origin is at the center. No effect for DTS files.

bool TSShapeConstructor::adjustFloor

Translate COLLADA model on import so origin is at the (Z axis) bottom of the model. No effect for DTS files.

This can be used along with adjustCenter to have the origin at the center of the bottom of the model.

See also:
adjustCenter
string TSShapeConstructor::alwaysImport

TAB separated patterns of nodes to import even if in neverImport list. No effect for DTS files.

Torque allows unwanted nodes in COLLADA (.dae) files to to be ignored during import. This field contains a TAB separated list of patterns to match node names. Any node that matches one of the patterns in the list will always be imported, even if it also matches the neverImport list

See also:
neverImport
Example:
singleton TSShapeConstructor(MyShapeDae)
{
   baseShape = "./myShape.dae";
   alwaysImport = "mount*" TAB "eye";
   neverImport = "*-PIVOT";
}
string TSShapeConstructor::alwaysImportMesh

TAB separated patterns of meshes to import even if in neverImportMesh list. No effect for DTS files.

Torque allows unwanted meshes in COLLADA (.dae) files to to be ignored during import. This field contains a TAB separated list of patterns to match mesh names. Any mesh that matches one of the patterns in the list will always be imported, even if it also matches the neverImportMesh list

See also:
neverImportMesh
Example:
singleton TSShapeConstructor(MyShapeDae)
{
   baseShape = "./myShape.dae";
   alwaysImportMesh = "body*" TAB "armor" TAB "bounds";
   neverImportMesh = "*-dummy";
}
filename TSShapeConstructor::baseShape

Specifies the path to the DTS or DAE file to be operated on by this object.

Since the TSShapeConstructor script must be in the same folder as the DTS or DAE file, it is recommended to use a relative path so that the shape and script files can be copied to another location without having to modify the path.

bool TSShapeConstructor::forceUpdateMaterials

Forces update of the materials.cs file in the same folder as the COLLADA (.dae) file, even if Materials already exist. No effect for DTS files.

Normally only Materials that are not already defined are written to materials.cs.

bool TSShapeConstructor::ignoreNodeScale

Ignore <scale> elements inside COLLADA <node>s. No effect for DTS files.

This field is a workaround for certain exporters that generate bad node scaling, and is not usually required.

TSShapeConstructorLodType TSShapeConstructor::lodType

Control how the COLLADA (.dae) importer interprets LOD in the model. No effect for DTS files.

Set to one of the following values:

DetectDTS
The default value. Instructs the importer to search for a 'baseXXX->startXXX' node hierarchy at the root level. If found, the importer acts as if ''TrailingNumber'' was set. Otherwise, all geometry is imported at a single detail size.
SingleSize
All geometry is imported at a fixed detail size. Numbers at the end of geometry node's are ignored.
TrailingNumber
Numbers at the end of geometry node's name are interpreted as the detail size (similar to DTS exporting). Geometry instances with the same base name but different trailing number are grouped into the same object.
DEFAULT
The default value. Use the value in the .dae file (defaults to Z_AXIS if the <up_axis> element is not present).
string TSShapeConstructor::matNamePrefix

Prefix to apply to all material map names in the COLLADA (.dae) file. No effect for DTS files.

This field is useful to avoid material name clashes for exporters that generate generic material names like "texture0" or "material1".

string TSShapeConstructor::neverImport

TAB separated patterns of nodes to ignore on loading. No effect for DTS files.

Torque allows unwanted nodes in COLLADA (.dae) files to to be ignored during import. This field contains a TAB separated list of patterns to match node names. Any node that matches one of the patterns in the list will not be imported (unless it matches the alwaysImport list.

See also:
alwaysImport
string TSShapeConstructor::neverImportMesh

TAB separated patterns of meshes to ignore on loading. No effect for DTS files.

Torque allows unwanted meshes in COLLADA (.dae) files to to be ignored during import. This field contains a TAB separated list of patterns to match mesh names. Any mesh that matches one of the patterns in the list will not be imported (unless it matches the alwaysImportMesh list.

See also:
alwaysImportMesh
filename TSShapeConstructor::sequence

Legacy method of adding sequences to a DTS or DAE shape after loading.

Example:
singleton TSShapeConstructor(MyShapeDae)
{

int TSShapeConstructor::singleDetailSize

Sets the detail size when lodType is set to SingleSize. No effect otherwise, and no effect for DTS files.

lodType
float TSShapeConstructor::unit

Override the <unit> element in the COLLADA (.dae) file. No effect for DTS files.

COLLADA (.dae) files usually contain a <unit> element that indicates the 'real world' units that the model is described in. It means you can work in sensible and meaningful units in your modeling app.
For example, if you were modeling a small object like a cup, it might make sense to work in inches (1 MAX unit = 1 inch), but if you were modeling a building, it might make more sense to work in feet (1 MAX unit = 1 foot). If you export both models to COLLADA, T3D will automatically scale them appropriately. 1 T3D unit = 1 meter, so the cup would be scaled down by 0.0254, and the building scaled down by 0.3048, given them both the correct scale relative to each other.
Omit the field or set to -1 to use the value in the .dae file (1.0 if the <unit> element is not present)

TSShapeConstructorUpAxis TSShapeConstructor::upAxis

Override the <up_axis> element in the COLLADA (.dae) file. No effect for DTS files.

Set to one of the following values:

X_AXIS
Positive X points up. Model will be rotated into Torque's coordinate system (Z up).
Y_AXIS
Positive Y points up. Model will be rotated into Torque's coordinate system (Z up).
Z_AXIS
Positive Z points up. No rotation will be applied to the model.
DEFAULT
The default value. Use the value in the .dae file (defaults to Z_AXIS if the <up_axis> element is not present).
