I got an idea to use a stucco texture as a bump map.
Stucco Texture
For the next render, I used the same texture, but I set it to a paint template, set the color to beige, and set the bump to SketchUp texture.
This one has bump size set to .5.
It’s not perfect, but I think it looks similar to a painted interior wall. Normally, painted walls are close to being a solid color (except grunge, tack marks, etc.) and the bumps create most of the texture we see.
