I'm having trouble with the Final Render creating extremely dark shadows or turning off lights on a certain camera angle or character position. The only way I've been able to resolve is turn ambient color off in PBR Setup, but then another character gets flooded with light from same angle as shadow on 1st character.

Lighting is good in Preview Render. I've also tried High, Medium, and Quick mode, but still get dark shadow. Below is a copy of video's rendered.

If you have already checked this, forgive me, but just a few weeks ago, I had something similar happen. Turns out that I had forgotten that my Auxiliary Light was on (it only shows up in Preview), and when I rendered, what I got was awful! Turning off Aux Light and making sure my regular lights were on solved it quickly. Good luck!76% of original size (was 666x19) - Click to enlarge

Thanks Terry. I had checked the Aux light. Wish it was that, but it wasn't. Only thing that's come close to working is playing with PBR, but then I still get saturation of light on another character. I can get some out by adjusting 3 light sources, but not all. The preview copy looks best.  

Go into Edit -> Preferences and look at the Real-Time Render Options as well as the Advanced options. It's described here in the manual:

If all of the boxes are checked, but the preview still does not look like the render, then I'm not sure.  If checking boxes causes the preview to look like the render then you can figure out what effect is causing the darkness.

Thanks Keith; I tried those also... used High, Med, Quick mode to change boxes form none to a few to all, but same results. Also checked/unchecked some that I thought might impact it.

I'm not totally sure but it seems that PBR is the issue. I unchecked "Convert All Shaders to PBR" in the Project PBR setup and that worked on the most obvious section. A few shadows were more subdued in short (200 frames) final render test, but it may work okay. I'm rending full project now, but that will take an hour or so. I'm still not sure this was the best fix, but it does get rid of really dark shadow.
