There is no documentation that i know of relating to 3D objects in catalyst.

You need to create your object in an external application like 3D Studio Max or similar - this is the clever bit as it idefines how the video is mapped over the object.

Then import the object in to catalyst:

Create a folder called 'Models' in the same folder as the application.
Name your model files using 3 digit numbers like movie files.

000Model1XXX.obj
001Model2YYY.obj

You can either use it within a mix - or on a layer if you need more controls than the mix offers...
