Hello Marcus,
3DS-files are not exported in the same way as VRML (from 3DS Max 7 at
least). Any hierarchy is lost.
OK, but when loaded into OpenSG, will a 3ds file have a MaterialGroup with a
ChunkMaterial as parent to the geometry node(s), like VRML files do? I'd like
to know because I'm trying to make a wrapper for OpenSG objects (so I don't
have too many begin/endEditCPs in my main code), and if objects from different
sources don't behave the same way I'll probably have to special-case it...
Yes. IIRC the format is similar, (three node(core)s per object
(transform, material, geometry)). Can't remember if it's ChunkMaterial
or SimpleMaterial though.
I usually convert most of the non-chunkmaterials to chunkmaterials, just
to get a uniform graph, but is some cases, one needs to work on both
(esp Materials in MaterialGroups vs. Geometries), so I have traversal
funcs that test which it is and give me the option to get/set material
regardless of it's container. Makes it a bit less painful.
