The bitmap name is used as texture name, not the filename
If the bitmap name contains no filename extensions the filename is copied to the bitmap name.
This was done to allow bitmap names such as "shaders/fx/decal.mtl", which can't be used as bitmap filename.
If the materials name contains .shd, it will generate an automatic luxinia material (MATERIAL_AUTO), using all bitmaps found in submaps of the material. See readme for details.
Generates a special .lua file that can be processed by the luxinia engine, to recreate collision nodes.
