The blood sprites in RTCW have always been a bit janky, it often looks like they're not actually displaying, particularly when shooting distant targets. The sprites kind of spawn inside the character models half the time, and they're very dark so often don't show up against the dark backgrounds. This is how it's always been btw, nothing to do with RealRTCW.
However I've been playing Enemy Territory Single Player and that uses slightly different blood sprites (and decals) which seem to work a lot better than the base game's. They seem to always display outside the models correctly and are lighter so they show up against the backgrounds better.
Don't know if this makes sense to anyone or not but my question is, is there an easy way to replace the main game's blood effects with the ones from Enemy Territory Single Player?
