My exterior lighting solution currently involves nothing but a movable skylight, movable directional light, sky sphere, and a sphere reflection capture. It mostly looks fine, but whenever the skylight’s shadows are enabled I notice a bunch of artifacting around any moving character. It looks a lot like the glitchy motion blur TemporalAA sometimes causes, but the blur is all black and shadowy. Disabling skylight shadows or turning DFAO off entirely gets rid of the effect, but that’s not an acceptable solution since I’m trying to power my entire project with GI. I’ve tried systematically enabling and disabling almost everything that isn’t DFAO in the hopes that it’s an unfortunate interaction between systems, but as far as I can tell it’s linked directly to DFAO; has anyone else experienced and dealt with this?
I can’t get a gif showing this in motion, since the compression tends to hide the blur, but I took a screenshot:
The character is walking right-left, and all of the shadow behind their character’s upper body is undesired and linked to the presence of DFAO. The blur behaves a lot like AA glitches, where it’s strongest when there’s a strong color contrast and the character moves quickly.
