Howdy,
I''ve got two model artists. One uses 3DMax and the other uses TrueSpace. Both artists save to 3ds files and then I run the Conv3ds to convert them to .x files.
With the Truspace-generated models, my game engine isn''t able to light them at all (all surfaces are rendered at full bright). I have checked using the DirectX mesh viewer and they appear to have vertex normals, and render perfectly in the mesh viewer. I also thought it may be a material problem (thought the material may be overbright or something), so I disabled the model materials by using a preset material for all meshes and it didn''t seem to make any difference. So, basically I''ve got models that have no vertex lighting on them even though there are (or appear to be) vertex normals, and I really don''t know why.
The odder thing is if I use the mesh viewer and ask it recalculate the normals and then save the mesh, it still doesn''t give me any lighting.
I have sat with the artist and tried changing the diffuse, specular and ambient properties of the mesh materials prior to export, but that makes about as much difference as forcing a preset material for all models... i.e. None.
Any help on this would be appreciated.
