EasyTok - Make Level specifications

I dont have 3ds Max and have been using ac3d, which doesn't export b3d files.
When I load a .b3d i converted from lwo or 3ds it doesn't display it.
I'm just using:

CreatePhysicFromMesh(LoadAnimMesh("level1.b3d"))

I displays if i just load it normally so I'm guessing its not the file.
it works if I use your room1.b3d file though.

Here's the model in x and b3d, if it helps:
.X level

.B3D Level
