@Arjan Pottjewijd (Cuflee) Please open a new report, with all required information (in that case, precise steps and all data (like image files) need to reproduce the issue are mandatory). Resurrecting years old reports is generally a bad idea, code has changed a lot since then (you may reference an older report in a new one, though).

I can confirm the same error on Blender 2.78. I've added some screenshots and a .blend file that is raising this error for me, though it also happens with the startup file.

Bastien Montagne (mont29) closed T61222: OBJ IMPORT BROKEN as Archived.

The main issue here is the 'blend mode' of the materials set to Alpha Blend, because of their MTL illum set to 4 (which, according to http://paulbourke.net/dataformats/mtl/, enables glass transparency and raytraced reflection). No idea why this is using that model, tbh.

Santeri Holm (Santerho) added a comment to T56792: Alembic doesn't export custom normals correctly.

This bug still seems to exist and is really getting in the way of our company pipeline.
I did some digging and seems like blenders vertex normals are exported to point normals

Eddie J. L. Christian (EddieChristian) added a comment to T61222: OBJ IMPORT BROKEN.

Ok so the mesh is fine but the Materials seem to be not reading in properly. That is good to know. I can tell you that the mesh has been tested in multiple applications and the .mtl file is being read in correctly. No scrambled normal maps , no transparent materials etc.. So at least now I know the issue is with the .mtl reader.

I have attached a zip with an OBJ and its textures. Just import it and select options : Don't change Vertex Order and Keep Polygroups.
Select Rendered Display render preview.
On FBX import it brings things in properly if the maps are in the same folder. This is not the case for obj import.

I included an image of the FBX import so you can see what it should look like.

Bastien Montagne (mont29) added a comment to T61011: FBX Export/Import armature child of another armature causes a bug.

Rule of thumb: never do that. the way FBX handles 'armatures' (aka chains of voids used as joints, basically, with some esoteric undocumented ways to distinguish what is actually part of a rig, from other 'empties' just used to create object hierarchies), you are pretty sure to run into issues with current FBX addon in Blender. This is kind of known limitation/unsupported feature (and we already have a report for that kind of issues, will merge).

Also, for what it's worth, Collada has the same basic problem as FBX. From what I can tell, this issue has less to do with the FBX format in particular and more to do with how Blender interprets and deals with hierarchies.

Since you asked for a smaller file, here you go. It's a 1MB file. It has a mere 4 mesh objects and a paltry 3 bones. That's about as simple as it gets.
