Im making a bunch of broken buildings for a war scene where the materials blend between bricks/plaster where its broken. Ideally I would use vertex paint to make buildings look different, but that would involve me vert painting a bunch of buildings, which is fine but a little time consuming... but I would get more variety…
Both. You'll probably use vert paint, being cheap and effective way to blend materials, and probably masks, even if it's just a basic noise and gradient material function to break up vertex paint blending or height lerp from a height imput for example. Also don't forget decals on top of what ever solution you use.
the simplest thing to do is chuck a world space noise texture or two in there to modulate your texture masks you can do cleverer things but theyre all based off that principle This is a quick mock up in designer (the noise and incoming gradient are both moved to -1:1 range, added together and the result clamped between…
