Rendering Errors

PostPosted: Thu Jul 16, 2015 9:37 pm

I'm experiencing random instances of "negative light" in my renders.
In spots where there should be shadow, I'm getting highlights.
And it is truly random. I can render the exact same scene back-to-back with no changes and get different results.

It seems I can mitigate the issue in post by layering multiple results in Photoshop and setting blend mode to "darker color".
But even with the randomness, there are still some spots that share the error in two renders. (I've not tried more).

The example is the same scene, literally rendered, saved, then rendered and saved again.
I've circled some of the more glaring instances, but there are many more. :/

Help!
