Hey,

Was about to make a thread flagging the same issue.

Everything working as intended on 5.0.3

Then entirely broken ray traced shadows in 5.1, 5.11 and also 5.2 which I just compiled from github.

Seems there’s no light contribution past direct lit areas, making SSS a bit pointless as it stands. Having to stick with 5.0.3, but really needed 5.1 for a couple other bug fixes.
