Is your feature request related to a problem? Please describe.
I'm always frustrated when I work with poorly exported meshes - it is rendered without any shading.
Such meshes are commonly provided in ROS2 description packages. Some examples you can be found here
https://github.com/husky/husky/blob/foxy-devel/husky_description/meshes/wheel.dae
The problem is missing UV mapping.
In the image left monkey was created in Blender and exported without UV, right, on another hand was created with UV.

Describe the solution you'd like
Have some simple shading when mesh without UV maps is imported

Describe alternatives you've considered
Generate placeholder by AssetProcessor
