ValueError: Cannot use face colors with a smooth mesh

[ChrisGoettfert]

Hi,

Thanks for your great work. I wanted to export animation videos and set the boolean save_animation (line 19) in main_test_avatarposer.py to True. This creates: ValueError: Cannot use face colors with a smooth mesh

Full output:

@ChrisGoettfert I faced this problem as well.

In body_visualizer/mesh/mesh_viewer.py :

Fix line 88: mesh = pyrender.Mesh.from_trimesh(mesh)
to
mesh = pyrender.Mesh.from_trimesh(mesh, smooth = False)

and it seems to work.
