I’m not sure is there a way to achieve something like this in unity. I’m familiar with other engines and they kinda have this stuff from the get go. Can someone point me in right direction? Please take a look at video to get idea what I have in mind.
Thank you for your time.
Use shadergraph to change the amount of smoothness present in the material, based on a mask. The mask is usually going to be the height you mentioned, which is just a texture. As usual, these things are simple but using words like wetness and height can confuse people what is really going on (smoothness, and a mask).
