Empty Viewport for OBJ files.

[KTBL-AlonRichter]

When adding an obj file, the resulting viewport becomes empty. This is true when using local files and linked URLs from other sites.

Hi.

Could you please give an example?

[KTBL-AlonRichter]

Sure, thank you.

This is the empty viewport I am receiving. My obj file is relatively simple, I'm receiving the same error when using off-site .obj files. I double and triple-checked the files themselves, they work well in other programs.
I also receive an error message in the console:

Uncaught TypeError: Cannot read property 'color' of undefined at load.php?lang=de&modules=ext.3DAlloy|jquery&skin=vector&version=1ocmk:631 at THREE.Mesh.traverse (load.php?lang=de&modules=ext.3DAlloy|jquery&skin=vector&version=1ocmk:105) at THREE.Group.traverse (load.php?lang=de&modules=ext.3DAlloy|jquery&skin=vector&version=1ocmk:105) at Object3D.load_obj (load.php?lang=de&modules=ext.3DAlloy|jquery&skin=vector&version=1ocmk:631) at load.php?lang=de&modules=ext.3DAlloy|jquery&skin=vector&version=1ocmk:632 at load.php?lang=de&modules=ext.3DAlloy|jquery&skin=vector&version=1ocmk:602 at XMLHttpRequest.<anonymous> (load.php?lang=de&modules=ext.3DAlloy|jquery&skin=vector&version=1ocmk:203)

The obj file used is this (I cannot upload .obj files in the comments here): # Blender v2.93.1 OBJ File: ''# www(dot)blender(dot)org mtllib cubes.mtl o Cube v 1.000000 1.000000 -1.000000 v 1.000000 -1.000000 -1.000000 v 1.000000 1.000000 1.000000 v 1.000000 -1.000000 1.000000 v -1.000000 1.000000 -1.000000 v -1.000000 -1.000000 -1.000000 v -1.000000 1.000000 1.000000 v -1.000000 -1.000000 1.000000 vt 0.625000 0.500000 vt 0.875000 0.500000 vt 0.875000 0.750000 vt 0.625000 0.750000 vt 0.375000 0.750000 vt 0.625000 1.000000 vt 0.375000 1.000000 vt 0.375000 0.000000 vt 0.625000 0.000000 vt 0.625000 0.250000 vt 0.375000 0.250000 vt 0.125000 0.500000 vt 0.375000 0.500000 vt 0.125000 0.750000 vn 0.0000 1.0000 0.0000 vn 0.0000 0.0000 1.0000 vn -1.0000 0.0000 0.0000 vn 0.0000 -1.0000 0.0000 vn 1.0000 0.0000 0.0000 vn 0.0000 0.0000 -1.0000 usemtl Material s off f 1/1/1 5/2/1 7/3/1 3/4/1 f 4/5/2 3/4/2 7/6/2 8/7/2 f 8/8/3 7/9/3 5/10/3 6/11/3 f 6/12/4 2/13/4 4/5/4 8/14/4 f 2/13/5 1/1/5 3/4/5 4/5/5 f 6/11/6 5/10/6 1/1/6 2/13/6 o Cube.001 v 1.000000 1.000000 -2.458512 v 1.000000 -1.000000 -2.458512 v 1.000000 1.000000 -0.458512 v 1.000000 -1.000000 -0.458512 v -1.000000 1.000000 -2.458512 v -1.000000 -1.000000 -2.458512 v -1.000000 1.000000 -0.458512 v -1.000000 -1.000000 -0.458512 vt 0.625000 0.500000 vt 0.875000 0.500000 vt 0.875000 0.750000 vt 0.625000 0.750000 vt 0.375000 0.750000 vt 0.625000 1.000000 vt 0.375000 1.000000 vt 0.375000 0.000000 vt 0.625000 0.000000 vt 0.625000 0.250000 vt 0.375000 0.250000 vt 0.125000 0.500000 vt 0.375000 0.500000 vt 0.125000 0.750000 vn 0.0000 1.0000 0.0000 vn 0.0000 0.0000 1.0000 vn -1.0000 0.0000 0.0000 vn 0.0000 -1.0000 0.0000 vn 1.0000 0.0000 0.0000 vn 0.0000 0.0000 -1.0000 usemtl Material.001 s off f 9/15/7 13/16/7 15/17/7 11/18/7 f 12/19/8 11/18/8 15/20/8 16/21/8 f 16/22/9 15/23/9 13/24/9 14/25/9 f 14/26/10 10/27/10 12/19/10 16/28/10 f 10/27/11 9/15/11 11/18/11 12/19/11 f 14/25/12 13/24/12 9/15/12 10/27/12
