[Twitch] UE4 Rendering - Apr. 9, 2014

Are there plans to improve the (already quite nice) decal system? I’ve been struggling to get it to behave “properly” in areas that are not lit directly, as seen here:

(EDIT: apparently the lighting problem has been fixed already, thanks!)

Also the bleeding onto objects other than the decal actor’s parent is sometimes undesirable. I’m not sure if this can be fixed with the current deferred decal method. I’ve been trying to understand the decal renderer, but I got lost in all the rendering code. Speaking of which, a general overview or crashcourse on Unreal’s rendering architecture and Unreal specific things would be nice too, if it fits the style of the livestream.
