okay not real sure how to ask this, but here goes, our entire level is meant to be old and quite plainly dirty, if there a simple way to make a “dirt” texture or “grunge” texture that could then be applied to any material and adjusted in the material editor to apply a “dirtiness” to any material, be it furniture or walls and floors, i know this feature was easy in cryengine and i assume ue4 has an ability to do it also, any help highly appreciated
A good approach for this would be using Unreal’s new Layered Materials system. You could make a couple of different dirt/dust materials and for each object you could make a mask, and within a layer material blend between the two.
Here are some links:
It’s not too dissimilar than setting up a landscape layered material that you allows you to paint areas of the mesh with different textures.
