How do you add a collider to a .FBX model ?

I have imported a FBX house model made in 3ds Max into MED and converted to MDL format.

In the game, when my character hits the wall, it passes through. How do I add a collider to the house wall please ?

Thanks

Did you set the polygon flag for the house?
You can do that in WED in the properties for the model or do it in script, "set(me, POLYGON);" in Lite-C, and "my.polygon = on;" in C-Script.

Thanks, I'll try that

Cheers
