Set dds texture to a material

Hello :slight_smile: ,
when i want to set a dds texture to a material the following error occurs :

Material parameter is not defined: Colormap

Here is my code :

Material mat = new Material(assetManager,
 mat.setTexture("Colormap", assetManager.loadTexture(new TextureKey("assets/graka/")));

Even when i change Colormap to Texture or something …the same error occurs.
Can someone help me?

Thanks :slight_smile:
