Creating textures for Torque shapes is fairly straightforward. You can use any paint/image editing program to create texture maps and then apply them to shapes in Maya. All shapes must have actual image files connected to the material's Color attribute. Procedural textures are not supported.
Specifications
Torque supports JPG, TGA, and PNG file formats. Note: PNG support in Maya 5.x for Windows is provided by the IMFPng plugin included in the File Pack.
Image file dimensions must be powers of two (e.g. 256x256, 64x64, etc). Textures do not have to be square (e.g. 64x128 is acceptable).
Tranparency
To make an object transparent, the texture on the object must have an alpha channel. The amount of transparency is controlled by the image's alpha channel. Applying an image file with an alpha channel to the Color attribute of a material will automatically apply the image's alpha channel to the same material's Transparency attribute. Both PNG and TGA files support alpha channels; JPG files do not support alpha channels.
Two-Sided Materials
Two-sided materials are supported by adding a custom attribute named twoSided to the object. The twoSided attribute is a boolean value that determines whether or not the shape will export with double-sided materials. This attribute can be added from DTS > Rendering Options > Enable Two-Sided Materials in the dtsUtility window. Maya's double-sided attribute is ignored.
Visibility Animation
Visibility animation is supported by adding a custom attribute named vis to the object. The vis attribute is a float value with a minimum value of 0 and a maximum value of 1. This attribute can be added from DTS > Rendering Options > Enable Visibility Animation in the dtsUtility window. Maya's visibility attribute is ignored.
