Me, before Nash fixed them wrote:I never thought I'd be releasing a [fail]ed wad, but here it is:
I've been working on these for Abyss Below and was going to release it as a resource, so mappers could simply place a decal actor to have a large blood splatter on a wall. I extracted the blood decals from the Doom 3 demo, greyscaled them (they were sort of luminescent, before) and put them in a wad. They don't show up properly, though, as the test map shows.
If someone could fix these decals and release them, I think a lot of people (myself included) could really use them. I've lost the will and don't have the know-how to fix them, myself.
