when i import files .obj+ .mtl+ .png, some objects are white ou grey, the texture is not on the object. My students are doing a project and they are waiting for a help.
Looks like Blender incorrectly exported your object. The mtl file doesn’t contain any information about the texture. You can try to re-export it or add “map_Kd TextureBoat.png” string to your mtl file.
I corrected it manually and you can download the changed file here Wood_Boat.mtl (258 Bytes)
