I made this cat cupcake. I think manually painting darker areas on the cupcake will make it look better. Everything is UV mapped.
However, the cupcake texture is currently procedurally generated. How then, do I do manual handpainting on this? Since I can’t just paint on a texture map.
Add your image texture right there above your stack of color ramps and add in a white image to paint to attached to your UV vector. Set it on input B of a new Color Mix Node and set the output of your top color ramp to input A so the image texture is multiplied to your procedural color by setting the mix mode to ‘Multiply’.
Image for reference, I didn’t bother replicating sizes of textures.
