Please attach a .obj file to reproduce the problem, as I guess this does not happen with any file.

Hi Brecht,

That is correct. Most obj files I have imported to 2.8 now work fine. Here's the offending obj.Adidas2.obj

This obj also produces the same error:
https://www.artec3d.com/3d-models/vw-bus

when I export this obj from 3ds max as obj... it imports into blender correctly.

Cannot reproduce with the Adidas2.obj alone.
Mind uploading the Adidas2.mtl as well?

Can confirm an error with the VW (but it is a different one...)

I've commited blender/blender-addons@a0e769eeb3 and cfb6f14616 now.
These should fix the VW Bus.

For The Addidas [the original report]:
@danny.austin: there are probably imagemaps as well, but thats fine for now...

There is still something wrong with the ImageTexture/Normalmap node not being created in the Adidas case...

@mont29: is this because of the lazy init? could you have a look?

Addidas file now imports OK, so think we can close that one.

Hi folks, it seems exporting from instant mesh gives this below error.
We can eliminate it by un-checking split by > Object | Group.
or using Keep vert order.
In Blender 2.79 checking those are working correctly.
In Blender 2.8 Before May 26, 2019 it was working correctly too. But after that it's broken.

@MD.FahadHassan Please check recent reports first, and do not re-activate old ones like that… FYI, it's reported in #65326.
