VRay Light (Exposure?) Flicker

[djanim8]

I'm rendering this scene and am having issues with the renders being "different exposures" and creating a light flicker (1 second preview attached). I have one HDRI light in the scene, have GI turned on with Brute Force and Light Cache (adjusted the GI light cache to have 3000 subdivs and 8 retrace) and I set the mode to fly-through. These settings were updated from posts I've found on these forums.

Is there any other reason this would be flickering?

have you tried LC with Use Camera Path option checked?

that appears to hvae fixed it (the whole rendering isn't done yet, but from what I have it's not flickering!) Thanks!
