Hi, I'm looking for a way to place an overlay to appear as if it were on top of a prop. I've tried creating a brush within the prop (with the top face just above) coated in nodraw or invisible and placing the overlay on that, but neither method lets the overlay show up in game. Is there any way to get this to work? If it makes any difference, the prop is props_mining/generator_pipe01_cap.mdl and the overlay is overlays/patch009. I'm looking specifically to use an overlay, not a decal.
