I imported a mesh using vertex color to affect a color to mesh faces. (From FBX format)
But There is an additionnal unwanted light blue color above the right color (for exemple above the red color on the picture)
How can I fix it ?
What software are you using?
I'm not sure about the colors yet, but the "wobbly" meshes are probably caused by a very big bounding box or coordinates far away from the origin.
