My crate models for my map have very buggy collision likely due to their intricate design. I have also made a mesh for each that's just a boring old cube. How in the odf do I tell it to use the cube model for collisions?

just call the collisionmodel collision_xxx in XSI, that will do the job
(same for the shadow: sv_xxx and lowrez: xxx_lowrez)

I use 3DS Max.


I did find a solution, however. I made a transparent cube to surround my model, which doesn't render, but is used in collision.

i think it doesnt matter which applications you use as long as the name is correct
