Ello,

I am experiencing a weird light flicker on a few frames of a shot rendered with Mental Ray. I'm using a simple point light to brighten up a few objects in shadow and have used the 'Light centric linking' to limit its effect to only a few objects. Every now and then, it's as if it forgets it parameters, as it will effect all objects and there will be an apparent spike in light intensity. out of 210 frames, a total of ~50 are affected, sometimes 1 frame at a time, some times up to 15 in a row. The light has not been key framed and there is no apparent change in any parameters.

EDIT: Should also note that it's not just an error with the batch render. Rendering the frames individually gives the same anomalies.

Any ideas?

Cheers.
