 Generating Materials
 --------------------
 
-As seen in the visual for geometry transformation, the importer now generates a material for each mesh in the node. The material in assimp maps to `SCNMaterial`_ in scene kit. The importer generates a texture if available for the following material properties: diffuse, specular, ambient, reflective, opacity, normals and light map. The material property in assimp maps to `SCNMaterialProperty`_.
