I do not believe this is a hardware issue. It seems that decals created by hitscan attacks do not appear onto 3D floors. But those created by projectiles do.

Seen this using the stock Doom weapons and a room with a single 3D block in the center.

Upon further test it seems as though it is not the hitscan weapons themselves, it is the standard doom puff. The chainsaw, and fist do not leave a decal on 3D floors either.

Those are also hitscan weapons so it is the same reason why it isn't working.

Fixed. Although there are still situations in which a decal might not appear on 3D floors. Unlike regular walls there are far too many special situations here that can't be all checked.
