stucci and craks

see pic

i give the mesh brownish one a stucci text but if i want to add some little crak but not all over the place

is there a procedural way of doing this ?


If you want to use a procedural texture, try to add a Marble one, with a high noise size. Map it to Nor Color, and maybe Spe too. That’s one solution among others.
If you want something more precise, you should consider UV mapping.
