As we all know 3D grass in AC is rather poop, and Bathurst has very varied grass verges and edges, all very patchy and uneven, so I needed away to add more variation, colour and control.
This is distributing meshes texture via color ID in Max, you can use the same multi-layer RGB mask to distribute the 3D meshes, so the grass aligns perfectly to the detail texture.
3 meshes:
Red for clumps, Green for edge strip, and Blue for main grass.
I still need to put it through it's paces and experiment with different mesh shapes, a mix of X and Y meshes would give better coverage on the main grass (blue) area, but I'm already pretty happy with the results the method produces.
