I ended up with a kinda cool looking pattern for donut icing. I've been trying to use it as a mask between two materials (icing and pastry) The problem I'm facing is that I can't figure out how to get the bottom of the sphere to be black so I can properly use this pattern as a mask. I tried with object and textures coordinates but no luck so far. Is it even possible or is there a better way to achieve what I'm trying to do ?
Thank you in advance for your help !
