Mixamo downloaded as collada and imported in BeamNG

[Harry00]

I downloaded a mixamo rig and it seems to play fine in Blender but when I import it into BeamNG I get this weird flickering. I asked in their discord if this is a bug in the game but they claimed it's a problem with the model. What could possibly be the issue?

I can't edit the post, so I will post as reply, I exported the model from Blender as FBX with embedded baked texture and then uploaded to mixamo, and then downloaded as Collada (.DAE)

Ah I found the problem. It's a Mixamo bug. When you download as FBX all is fine but when downloaded as Collada, Mixamo adds some messed up custom split normals. I just cleared these custom split normals in BLender and all worked well.
