I’m trying to figure out texture paint and so far I can paint in white or bright colors on the model. I’m using a black image as the base in the UVeditor.
When I choose black or anything dark though I can’t see what I’m painting. I’m painting in Mix mode, because I can’t see neither color (any) when using multiply et cetera. And for some reason, erasing (with the eraser on the pen of the tablet) only works in multiply, not in mix brush mode.
Why is that, and how can I paint in dark colors on my model?
This is what my node setup looks like. The upper image texture is the black image I use to paint on, the lower one is a grungy texture to mix with a color, for the base.
I think I haven’t quite understood this yet. It would be great if someone could explain this. I’ve followed several tutorials but this isn’t clear to me yet.
Edit: Painting in black on the grungy texture results in those places being transparent. I have no idea what I’m doing wrong here. When I choose white as the ground color, the whole thing gets a milky overlay.
You don’t understand cycles shader nodes.
You are putting color output (yellow dot) to shader note (green one).
gray dot is black-white you can connect it to gray, and yellow
yellow dot is color information (RGB) you can connect it to other yerllow or gray(but you will lose color information and have only black/while information)
green is shader, and you can connect it only to other green’s
ofc as you did you can connect it as you wish, but it dosen’t have any sense.
Maybe watch some tutorials:

Oh yeah, I didn’t even notice that. At one point I was trying to switch everything around to try another way and must have messed that up. I was aware that the the colored slots should ideally connect to same colored parts.
Anyway, what I’m trying to achieve is have a green metal base material for the model, and to overlay a dirty texture over it (with multiply or similar, so it blends together). Then paint on top of that with white, black, brown and so on. Basically trying to paint a metal object dirty. I did watch tutorials, including the first one you linked but wanted to try something myself that I hadn’t seen in a tutorial yet and got stuck.
I would recommend using Blender Internal for painting the maps first, then use those same images plugged into your cycles node tree. By using GLSL shading in viewport, you can add a few lamps and see what you are doing more easily.
