Quote from: Dune on April 25, 2020, 01:54:56 amI used an RGB dots map to spread the pops of reindeer. I think it's possible to make RGB maps by fractal in TG itself, but it depends on how blue blue is, and how red red and how green green. Never did that actually.
Quote from: WAS on April 24, 2020, 11:33:29 pmI always have to explain this every time it's brought up. Alpha is hard. Create a Cloud map in PS. Load it up, create transparency from colour... This is why was having issues using PFs and alpha with caustics based on water, or default shader and transparent materials (with transition). Even with the hard shape tool in PS the blue squares have a blue border when using blue as a key, when you up tolerance it doesn't effect it until it bounces PAST this blue by a pixel it seems, and any further starts intersecting brown and red, with no blue in the channels (in my example file above)Also quick edit is posting to a 404.
