This morning I decided to take a look at the rock shader again before I go onto something else.
I’ve added moss to them so depending on their orientation the moss will always show based on the specified vector. Then I added some extra control for the falloff and intensity.
Rocks! So i’ve had a play around with the best method for making the rocks and I think, I hope, I have a method. Also the shader we were using sucked quite a bit, there was very little control.
So in the second image you can see the node tree and how the new shader is done, it most likely needs optimizing no doubt.
A year today I started working here at Facepunch. Man, what a ride so far!
