Hi guys,
No idea what is causing this issue, but from the image uploaded there is something happening to the upper part of the mesh when using a CC rig when exported as .glb from Blender.
I have added a spotlight, and all the other meshes is receiving the light as expected.
We have an application based on Unity. As you see, all the meshes are OK, except the one using a CC rig. The upper part is dark and don't take the light except from the sun.
Have any of you come across anything remotely similar? UVs, mesh and materials have the exact same setup. This very same thing has happened to two more characters using the CC rig.
Appreciate any feedback that can point me in a direction that makes sense :)

Replying to my post here:

I figured out how to deal with this. Because of scale issues in Blender there are two solutions.

1. after import via CC-pipeline add-on, join all the meshes into one monolith and bake materials to one texture set (an atlas) if multiple sets.
or
2. on import via the CC-pipeline add-on, also check Rigify. Then retarget and bake the motions.

Cheers!
