How do I get a decal to project onto a glass surface type?
Bullet impact decals, for example, work when I drop in and just start shooting but if I add the Misc/Decal object type, set it to deferred, line it up so it projects nicely on a standard illum surface then switch to glass, the decal disappears.
Also, I don't think this is solvable, but I've noticed any decal that works on a glass/transparent surface, all disappear when you angle your view so the decals are over sky or ocean instead of land.
