Decals affecting objects that have NoStaticDecals = 1

Wesley

Hey guys, pretty simple problem that I've no idea how to fix. I've got some decals on a solid, I've then got brushes in the affected area, I've set these brushes' "NoStaticDecals" to true. This works fine, until I add a bump map to the decals. This then causes artefacts on those brushes.

Image helps!
