Just wanted to make this small post, as a side project I really wanted a quick way to get good looking clouds in 3DS Max, without any Plugins. I came up with this which is still a WIP right now.
Its using all Max Shaders and PFlow only, However since I have just upgraded to V-Ray 3.0 I wanted to test the speed with the Progressive Renderer. I made little demo video showing the un edited render speed also. These are not meant for hero clouds, for that I would go down the FumeFX route but for clouds that are gonna be heavily blurred in comp anyway they work very well. I still need to work on the shaders to get more scattering/Translucency to them.
