I managed to figure out a way to to make it (kinda) work. Basically where he put the 0.5 values for the puddles I have them at 0.2 now. That fixes at least the issue with the puddles. I made it into a parameter so I can adjust it, should I have differently set up textures.
Snow still is a problem but I will use the Ultradynamic Sky snow for now, but it’s not ideal.
