Create your physic model, and as you did it for the reference model, you have to do a right click on the “Layer Physics” and then click “Membership“.
- on the left column, select the physics layer
- on the right column, select the physics group node and the shape node that contains the geometry.
Maya Relationship editor – Set the physics layer relationship
Select the object model in the view port, and do a right click on the viewport, choose then assign an existent material, to the physic model, and choose the same shader that the reference model already use.
If the shape node is not included, the geometry will not be exported correctly in SMD Physic format.
Textures maps on the collision model
The physic model require a shader material too or it will not work in game, here i just duplicated my cube and so the same shader is automatically applied.
