RenderStyle ReverseSubtract

Functionally the same as the TEXTURES version (I think), creating a "multiply" effect.

Alternatively, call it Multiply. :P

Multiply would be a misnomer, since actual multiply does, you know, multiply the pixel values by each others. Besides, if it's called ReverseSubtract in TEXTURES it should be called the same elsewhere too.

An actual multiply might not be a bad idea.

ZDoom: The Photoshop you code. ():)

Actually, it wouldn't be a bad idea to have either of those, the effect looks kinda cool. Multiply would be a little more subtle than reverse subtract, though. You'd have to be careful using it, because ReverseSubtract would be nearly perpetually black against dark backgrounds - of which there are quite a lot in Doom, especially with dark light rooms, but it might work for certain special effects, though.

Multiply would work a whole lot better with darker images and darker backgrounds because you'll still be able to see both the image and the background if they are both dark.

The intention is to create a different kind of spectre-type look, yeah. Using the fuzz style is basically flat-shaded, so you lose detail and recognizability.
