Short description of error

Importing in the following files give an error in blender 2.8

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).

Choose File Import Wavefront (.obj) choose the files called Tire_Original_Test_LW2018.obj it imports in fine

Choose File Import Wavefront (.obj) choose the files called Tire_Original_Test_LW2019.obj it gives the following error

Choose File Import Wavefront (.obj) choose the files called Tire_Original_Test_LW2019.01.obj it gives the following error

If you try and import any of the .obj files below in previous versions of blender they all work

Hope this helps

UPDATE: I noticed that the Tire_Original_Test_LW2018.obj had the UV mapped stripped from the file which allows it to import into blender 2.8

but the other two models below still have the UV maps in the model and these will not import into blender 2.8

Tire_Original_Test_LW2019.01.obj
Tire_Original_Test_LW2019.obj

So from the looks of it. It looks like it's an issue with UV maps in the model.

Hope this helps

I the same issue with a model exported from Maya. It has UV's (that are an utterly awful mess), imports just fine in 2.79 (with the awful UV map) but fails in 2.8.

i also have prolbem with importing 800mb tank object. it works fine 2.79... and also it works if i link object from 2.79... however it dosn't want to import in 2.8.. but it works fine in 2.79 tested build from 02/06/2019

These are caused by one of the parsing performance improvement commits on Nov 20.

@Bastien Montagne (mont29): I think you're much faster nailing this?

Hi, There is still an issue with importing in .obj files that have pure black in the color channel.

If you try and load in a .obj that has any surface with pure black Red=0 Green=0 Blue=0 on the model you will get this error message

This model below has it's surfaces set to R=0 G=0 B=0 ( it will not import into blender latest version Feb 21 2019

This model below has it's surfaces set to R=0 G=0 B=1 (it will import into blenders laters version Feb 21 2019

Hope this helps get to the bottom of the bug

This same bug above is in the latest stable version of blender 2.79

Thanks,
Jason
