-///
-/// Ignored attributes: "creaseAngle", "convex", "solid".
-///
-/// Texture coordinates generating: only for Sphere, Cone, Cylinder. In all other case used PLANE mapping.
-/// It's better that Assimp main code has powerful texture coordinates generator. Then is not needed to
-/// duplicate this code in every importer.
-///
-/// Lighting limitations.
-/// If light source placed in some group with "DEF" set. And after that some node is use it group with "USE" attribute then
-/// you will get error about duplicate light sources. That's happening because Assimp require names for lights but do not like
-/// duplicates of it )).
-///
-/// Color for faces.
-/// That's happening when attribute "colorPerVertex" is set to "false". But Assimp do not hold how many colors has mesh and require
-/// equal length for mVertices and mColors. You will see the colors but vertices will use call which last used in "colorIdx".
-///
-/// That's all for now. Enjoy
