Map Mask Texture
The Map Mask Texture is the image that selects the texture and where that texture is used on your track. The scene file for your track maps a texture to each channel in the Map Mask image. You paint in your Map Mask image where you want those textures to go.
The Map Mask image is 1024 x 1024 for an SX track and 2048 x 2048 for a National.
Map Mask Alpha Channel:
The alpha channel on the Map Mask appears to turn on the wet look to textures. More experimentation is needed. Use a black alpha and where you want the textures to appear wet use use some percentage of white. Dell Lago Orlo uses 50% white where there is snow and Moto 448 uses 128 where there is water.
Map Mask main image :
- Overlay_Base texture - Paint black where ever you want your main dirt texture to be. Normally most of your track path will be this color.
- Overlay_R texture - Paint Red where you want your red channel texture to be. This would normally be an alternate dirt.
- Overlay_B texture - Paint Blue where you want your blue channel texture to be. This seems to be typically a grass texture or off track texture.
- Overlay_G texture - Paint Green where you want your green channel texture to be. This seems to typically be rocks or an alternate grass texture.
It is possible to mix your R, G, B textures. Moto 448 uses Blue and Green together to mix grass and leaves.
