Hello. The wood brush stencil is not working as it should when I try to paint on the new texture 'wood details_1'. Only the white areas are being painted, while the black elements remain unpainted, but it should be the other way around. How can I make it work as it should, because it is not explained in the tutorial?
Here are some screenshots of what I'm working with. I followed everything step by step as in the tutorial.
In your nodes swap the a and b. 0(black) in the factor is going to show input A. 1(white) is going to show input B. Greys will show a mix of A and B.
Swapping a with b doesn't work. I also tried using the inverted stencil, but it still paints both the white color and the black background.
"...it [...] paints both the white color and the black background."
Yes, Sylvia,
Wherever you paint, that part of the Stencil gets 'stenciled' on the Object (if you paint with white, you change the Alpha of the Stencil from 0 to 1, wherever you are painting).
It's a bit like a 'tattoo sticker'.
Picture it like when graffiti artist use a stencil, they place a cardboard box with a hole on it and if they spray it with yellow paint, the yellow paint goes through the hole and paints on the wall. That is essentially what you are doing using the stencil on a 3D model. The white parts in the texture are like the hole on the cardboard box, the black parts of the texture are like the cardboard box itself that block the spray. So the white part in your texture will let paint stick to the 3D model.
White lets through, black stops.
Keep in mind that if the black part on your texture is not totally black pixels, it will let paint through, because it has a bit of white. And if the white part is not totally white, it will start to block paint, because it would have a bit of black. So the less black the black is, the more paint it will let through, the more black it is, the more it will block paint. Same for the white. Totally white lets 100% of paint go through, as you lower the white the less color it will let through.
