Info overlay

It adds a texture such as a sign or stain onto a brush. Place them with Hammer's overlay tool. The overlay tool can also distort overlays by dragging the 4 white squares.

Overlays may look wrong over faces of multiple angles or where they may be viewed up close at an extreme angle. This is because overlays are not actually applied to the texture, rather they sit about .25 units above it. Normally this gap is not noticeable, but there's no good workaround for this.

Overlays will work on any world geometry, including and  brushes. A map may have up to 512 overlays, or 1024 for CS:GO. If an overlay is set on a spot which has several (over 64) faces nearby, the overlay will count these even if the faces aren't set to the overlay. This will then cause to crash and report: " ". should be used here.
