Title: Emissive Bloom Lighting
Post by: oneofthe8devilz on September 23, 2015, 05:39:08 PM
Re-Watching the latest "new" Doom Trailer, I noticed an effect that is commonly used in pretty much every new current engine generation.

"Emissive Bloom" for projectiles and particle effects:

Not knowing much about shader and graphics effects coding, I was wondering what it would take to port that kind of effect to idtech4...

Is anyone experienced enough with that topic to make a statement ?

this is some variation of the screen space reflections, but i don't know what it is, it's doing the same that doom3 does with specular lights but rendering it with the whole world.

and also the roughness difference in the material definitions
