the attached .skp file contains a single face that looks colored in brown in SketchUp. According to the C API, its material type is SUMaterialType_Textured. But the image texture is almost white.
How to know that the material color should be taken into account ? How are the image texture and the color blended (if they are) ? What is the differece between SUMaterialType_Textured and SUMaterialType_ColorizedTexture ?
