Here's the simplified avatar, which also causes same crash: http://oaktown.pl/golden_dragon_2/golden_dragon_crash.fbx

Did you pack the textures? when I open it in Blender its purple. It looks for SCADA_1_colors.png in the material and could not find it.

[Basinsky]

I also see there is no weightpainting on the mesh

[ksuprynowicz]

Thanks! It turns out vertex groups were named wrong. The interesting thing about it is that when the model was exported as GLB, it was handeld gracefully - it was stuck in T-pose. For FBX it totally crashes the Interface.

Hello! Is this still an issue?
