hi all.
i'm using b3d file as a level to use with my project ( i created the levels with 3D World Studio 5.47) any way, when i try to load another mesh (like another b3d file, or even a 3ds file) it's not being loaded (or positioned correctly, cuz i cant' see it) and then it works correctly when i try to load the same 3ds file with out loading the b3d level, what's the problem?

thx

I would be easier if you post your log.

you tried moving the camera/mesh around? meshes are not automatically in the right spot, it's up to you to position them correctly. The camera might be inside the mesh.

thank u, but this problem is solved
it turns out that the mesh ar soooooooooooo small ( i needed to scale them up), sorry for wasting this space
