I have created a wall with Texture, Normal, Bump Map. Now I want to have multiple graphics on this wall, but in such a way that they look like they were painted on, or sprayed on. So the wall texture should be visible through the graphics.
I have been able to apply one graphic with a second UVMap and an RGB Mix Node.
But now I want to apply several graphics like this, but I don’t know what to do. I also want to get as much flexibility as possible for each graphic.
Or am I doing something fundamentally wrong here? Am actually still a beginner
using the image setup with you have there with the mix note with alpha to factor should be repeatable no? meaning you should do the same thing again with a new graphic, ie - mix the new graphic with the input currently slotted into the base colour socket, and plug the new mix node into the base colour socket. It should be repeatable ad infinitum.
What i like to do is, if you have photoshop, you could replace the bee2bee2.png file with a .psd file, and work in photoshop. by using a psd file, you can save the psd file, and press reload image in blender which updates the changes. This gives you the flexibility of making constant changes in a relatively clean manner, instead of having an overly messy node group, and having to adjust things with xyz coordinates.
