I guess this applies to different mapping, but I’m doing a bump map atm
So I have a grey image as my bump map, and when I scribble dark grey on it, the bumping interprets that as where it should deepen, when I scribble white or light grey on it, the bumping is outwards… as I want it
I am wondering what Blender does to recognize the grey as the neutral colour? Meaning the colour that it doesn’t bump either way… Is it because it’s the most common colour or something?
I thought maybe it looks at the brightest colour and the darkest and uses the average of those colours as the neutral colour, but when I have the primary colour as black and scribble white, it takes the black as the neutral colour and acknowledges the white colour as what I want to bump.
Does anyone know?
