I'm playing around with apple's downloadable "capturing body motion" file, and I cannot seem to figure out how to adjust the lighting on the mesh, it currently appears too dark. If it is possible can shadows be added too? Any answers/suggestions would be appreciated!

Whenever I transfer a rigged object from blender to Reality Composer (via "GLB" --> Reality Converter --> "USDZ") I face an issue in which unnecessary shading appears along edges of some polys. This issue ONLY occurs when the object is connected to a rig (as demonstrated in the images posted below). I found that converting GLB --> USDZ via "echoAR" does not share this problem. Has apple addressed this issue? I'd prefer to use reality converter if there is a solution.
