Materials can either be any material you want or the default material, which is much better performance wise and allows the player to colorize the furniture. If you don't specify a material, the default material will be used and the meshes should be UV mapped according to the texture shown below. You can supply a default material with your own texture. The red color channel will be mapped to color 1, green is color 2 and blue is color 3. Grayscale pixels will not be color mapped. The alpha channel controls smoothness/specularity where 99% transparent means full specularity, 100% transparency is specifically used for glow in the dark, note that Photoshop destroys RGB channels for transparent pixels when you save as PNG, unless you keep the alpha mask on your layers before you save. | Materials can either be any material you want or the default material, which is much better performance wise and allows the player to colorize the furniture.
