Alright, some more details.
I'm converting some constructive geometry models from BRL-CAD into faceted
models in OBJ format. I'm converting them region by region in a
constructive geometry sense. Each region becomes a group in an OBJ file
sense.
Now, each region has a material value
Robert,
At the moment the OBJ loader builds a material to stateset map, which is
indexed by the material name. However when the stateset is applied to a
geometry, the material name is effectively lost.
Also the OBJ loader reads the group name (i.e. g groupname in the .obj)
and any object name
Hi,
For reasons that aren't relevant I'm trying to merge multiple .obj files into
one. Each .obj file fairly small and includes the typical mtllib, usemtl
statements then is followed by the g group name then the list of vertices v
then a list of facets, f. All very normal, I can load and

This does, technically, work. However, in the final, merged, .obj file I've
lost what I specified for mtllib, usemtl and the group g names It
looks like all those have been auto generated? Am I missing something? I
know there is the ability for
