It is not uncommon for multiple logical textures in an FBX to reference
the same filename. Each such filename should yield one buffer view only,
and all sharing textures should reference it.
- alphaMode is only BLEND for transparent materials.
- We use RawMaterial.type to figure out what's transparent.
- FBX TransparencyFactor is not opacity, but 1.0-opacity.
- Treat vertex coloured materials as transparent
- We should at least iterate over vertices here and see if any of them
actually are transparent
- Sort triangles properly: transparent ones render last!
- Nix GetFileFolder(). It was not helping. Always search for textures
- near the FBX file.
- Use RawTexture::name for the texture name and ::fileName for the
inferred local filename path.
Digging the property values and texture shadows thereof, associated with
a certain FbxSurfaceTexture, should clearly happen once per material,
not per polygon. Furthermore there is a pre-existing pattern of
Fbx-specific accessclasses in Fbx2Raw that we should follow.
Soon we'll be extracting more than Phong/Lambert properties here, and
then we'll need to do further refactoring.
We were mapping v to -v rather than 1-v, with fairly catastrophic
results. While fixing, take the trouble to introduce a more general
transformation mechanism than just an affine matrix.
