During my time of workflow improvement and texture skills improvement I have sculpted a few Insert Multi Mesh assets. For example this set of rocks.
This shader is still Work in Progress, but the gif shows a clear idea of the shader in several states of wetness on the surface. But the main thing that got me stuck with this shader is the blending/animating of one wetness state into the other one, I want to create one state of wetness "flowing" into the next state of wetness. This is rather challenging for me mainly because of the fact that I'm not a programmer or shader artist by trade, so figuring this out is pretty crazy.
