Remesh a plane

we add a multi resolution modifier


it distorts the mesh

we can choose the simple method
click on Simple multiple times until happy with the mesh size


more faces

we can then bake the sculpt over the original and paint on top of it
Technique PBR
We can also add a PBR material on top of the plaster


We can also use the PBR as base material for some procedural texturing in the shade editor

We then create a new material for the plaster

Bring the PBR in Control + shift + T


we add a mix RGB


if we change the option to color overlay


Another way to influence the color is with a color ramp





We can now add some ambient occlusion


I want to combine the ambient occlusion and the color ramp. Control + shift + rightclick


We need to flip the colors because we want the ambient occlusion to influence the main color

we now need to add a color ramp


we now start to see the ambient occlusion effect when we move the black up


We now can modify the mix option to multiply

the difference is much better
