ReaderObjReadSceneNodes(Stream, FuncString, Stream, Material) Method

Reads the 3D models from stream and returns the 3D model(s) as a GroupNode that contains MeshModelNodes and other GroupNodes. When the obj file have any additional resources (materials and textures), the resolveResourceFunc must be set a method that converts the resource name into Stream. The method will not return null but an empty GroupNode in case no model is read.
