+///
+/// 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
