MESSAGE:
After a bit of back and forth and with the Help of Dino, Lino and Ricky with the enabling tip, here it is, the eagerly awaited Foam shading Tutorial.
I think this technique can be translated into a lot of different renderers as well as most of them let you alter volumes with textures.
If the reaction on the net to my teases is any indicator this will be my most watched video in the future. Let´s actually see.
I hope you get good results. Feel free to tag me with whatever you get out of this exercise
