Always wrong collision model when compiling.

[TheRiyoShi]

[B]Hello![/B]

I made a static prop for Garry's Mod so I obviously made a collision model for it,
but after compiling the model, for an unknown reason, Crowbar Compiler decides to change the collision model to something else:

Before compiling :

After compiling :

Could somebody help me please?

[B]Thanks![/B]

The vphysics collision model is not a single convex hull. [U]If not set, it'll make a single convex hull out of whatever geometry you give it.[/U][/QUOTE]
