God rays, visor reflections / water drops, lens flares, depth of field, night & thermal vision scopes, rainbows, dynamic wet surfaces with reflections, and many other effects. BETA UPCOMING!
Just a quick vid showing a new thermal/infrared effect I've made. Doesn't use any heat map, so it's purely fake - but still nice, I'd say.
Yes I know there is a mod that does something similar, but believe me, we don't share nor steal each others code :)
