View Full Version : Dynamic Real-Time Soft Shadows?
11-25-2011, 10:18 AM
Is it possible to make realistic dynamic real-time soft shadows in UDK? Not those good dynamic, but crisp/ soft-only shadows the engine has. I know there are soft Static shadows of hard-to-soft state which can be produced by a Toggleable Light, but the problem is they're Static so even if I put a Dynamic Light into the level and set CastSelfShadow - the player casts only ordinary shadow, not a good soft one...

I think you mean real softshadows ala area light.
I think you can just have hard shadows with soft blurry borders, but not real soft shadows.
Real area light effect can only be done with lightmass.
Arealight are very performance consuming in realtime.
Almost totality of today realtime soft shadows are just fake using simple shadowmapping with greater filters with generally poor results expecially for large kernels and tend to apply the same blur at any distance between caster and receiver.
The most qualitative solution in a real product is 3dsmax 2012 one but it is far from realtime (it iterates between frames).

Yeah I saw 3dsmax 2012 and it's just awesome! Another great video is about MoCap but shadow is pretty good there: http://www.youtube.com/watch?v=hlimlZAKnA4
I think it's kinda milestone that real-time shadowing should achieve))
But how can I get those soft blurry borders of dynamic shadows in UDK?
