I asked this in the nvidia gameworks thread but i thing it may be better to ask here.
I was trying to get with UE4.10 VXGI soft shadows like the ones you obtain with area lights. The problem is that when using a plane with an emissive material i just obtain a broad shadow for the whole object and not self shadows.
Look for example at this Head from the demos that comes with ZBRUSH.
And here are some of my settings
In comparison here is the same geos in Thea. The renders have self soft shadows which is what i want to have in UE4
And here is other with the Plane light bigger making the shadows even softer
So, is possible in UE4 to have soft self shadows from plane lights (like area lights)?.. for moving objects not static…!!
