Would someone (Dune, anyone?) mind posting a simple (well simple as possible) project that demonstrates how one might use the simple shape shader for creating rivers and roads. What I'm after is how the same SSS can be used to create the shape of the river\road, a smooth, none abrupt displacement that lowers it into the ground and then how it can be used for the placement for other things relative to the river\road. For instance rocks that follow the river's edge, grass down the centre of an old road or simply to keep populations off the river\road and reasonable distance from it.
I understand the basics and how important the colour adjust shader is but I don't think I have the full picture, especially with regard to twisting the sss in the first place and then creating masks that are relative to it.
I think this would be really useful for a lot of people.
Thanks in advance.
