I’ve been looking at the demo files for graphics and I’ve come across something that I don’t have any idea of how to create.
I know to create a bump map (at least I think) you need an original image, and then one that has (from what I’ve seen) blue and then purple-ish violet color to produce the ‘bumps’. My question exactly is, how do you create that second odd colored image from the original, is this something you can do with say Photoshop? Or some other software, or something else.
Any help is much appreciated.
