I just read another older thread by a user who’s having the same problem as I.

I’ve been downloading a bunch of items from other 3D model sites to use in my SH3D project. They either originated as obj. files or I converted them in Blender, but I can’t get the obj. files to recognize or connect with the textures in the mtl. Files.

I’ve uploaded one of the model files here for examination.

I originally got the file from here.

I’m new to 3D modelling, but I understand the obj. file is just describing the form of the object while the mtl. Holds all the other data for it. I noticed that there are spaces in the name in the object file, “mtllib Star Trek Tricorder MK VII.mtl”, but I think there’s got to be more to the problem than this?
Can anyone shed some light here, please?
Thanks!
