How to add leaks / grunge textures to walls
I'm wondering how to add leaks or grunge textures on top of a wall material such as concrete, to achieve a worn look-- attaching a few images for reference. Any help appreciated!

This is a perfect use case for Decals.
PS
I am looking forward to Decals being added in the Cosmos browser.

Re: How to add leaks / grunge textures to walls
I was playing with decals and it does work nicely, but only if I need it on one face. If I want to create a projection to wrap around all 4 sides of a box for example, would I just have to create 4 seperate decal objects?

Yes.
Or you could just use the good old overlay texture to your base texture (either by material stacking or by a layered material).

You can also do it procedurally with textured AO -

and possibly with the v8 curvature map -

Hope that helps! :)

Just for fun: There's always the Distance shader, too, Corona's universal weapon ;)
