I’m having the same problem with translucent ray traced shadows in UE4.24… dark shadows with glass objects. I’m doing interior renderings but I’ve had to turn off shadows on windows so light will come through. Translucent shadows also doesn’t work with subsurface shaders anymore either. I was able to get it working with previous versions of UE4 for materials that would be used on curtains.
I’m not sure if it’s related but glass objects will even look almost black when ray traced shadows are on unless I turn off shadows under ray tracing translucency in the post process volume, the refraction looks correct but then the glass item looks like its glowing. Its really frustrating, I really need to get this to work… I’m not sure if its a bug or if there’s something I’m missing. I swore that translucent shadows were working in 4.23, but now is seems totally buggered.
Any help would greatly be appreciated. Thanks!
