i have a concrete unit mesh. i want to apply material to it which randomize itself each time with each instance of the mesh; because otherwise its looks too repetetive. can i achieve that in unreal? here is the screenshot. The wall is not a single mesh! Every concrete unit is instances of concrete unit mesh; this is not a big wall texture tiling.
As Steve_T mentioned, you can add a dirt mask that adjusts it values based on World Position. An Example of this setup can be found in the Unreal Realistic Rendering sample project, look at the materials for the books on the shelves.
You could also add a Dirt Mask or grunge mask over all the units based on a World Aligned Texture Function. YOu can read more about that here:
