Unsolved No material on a custom object

I made this object with blender.
The material editor in the world editor shows that a color map is assigned to the object, but as you can see, it does not work.

 

Thanks, there is an error "unable to find material mapping to: [material-name] in cache 0.14.0.2/levels/.../theobject.cdae

The path seems to be correct, so i don't understand why it doesn't find it :/

 

Did you edit the "material-name" part or is the game putting it that way ?

 

Its not the original material name.
This problem is also solved, i completely re made the materials.cs file.
