You can change the color of the materials by clicking on "Settings" and open the "Materials" panel. Grab the material on the screen, and then drag the color wheel until a desired colored is set. Two things to remember:
- If a material already has a texture map on it, it will not change color.
- Modelo automatically groups materials by their layer/workset and their material properties. Materials of the same layer and same property will always be grouped together.
