Up until now all my algorithms for generating splat maps have relied on flattening the terrain and operating on it as an image.

Here's an extremely early test of a splat map implemented as a Cycles shader, using Dirty Vertex Colors and vertex normals.



The above only took ten minutes to do, but I'm posting it here because I might not work on it again for a while.

Okay, so I guess I lied when I said I wouldn't work on the splat map algorithm for a while.



Settings:

Looks pretty cool. I'm very interested to see where you are going with is.

Looks nice! Where you will add the river?

Oh, this terrain is just a test model for the algorithm. I have yet to figure out exactly how to model the actual track's terrain.

I should probably link to the model, actually.
