Serious problems with GI cashing in 9.6!
 

I have a serious problem to organize GI cashing for longer walk-through continuous animation.
As I don't have movable objects in a scene, I try first with FG.I made some tests on particular frames through animation, and when I got satisfied with settings, I bake radiosity for a whole animation.But...As render progressed, the results of cashed GI sampling seems to become less and less satisfied!On the end of animation, I got very obvious blotches, and I didn't have those in my particular tests before cashing!!
Also, if the rendering iz organized over more machines, or network, looks like only safe non-flickering preprocess method is "locked"- every other seems to make flickers.But, again, with what results?
I also try cashing with MC and Animation checked in scene with movable elements, but that's weird too!I also set preprocess on locked.When the render starts on a single machine, as it progress, the render time per frame becomes longer and longer.If I stoped rendering, and hit f9, I got much better render time. Also, rendering from a different machines in this case resulting with flickering, and the preprocess is set on locked!
In both cases I put frame steps on 2, or 3, considering the pretty easy moving of camera.Maybye I should put even more..
Anybody has an idea what to do?
Please help.

What format are you outputting to?

Sequence..tga, sometimes .exr. But, that can not influence any of this problems, I guess.

Hmm sounds like quite a problem.

try .tif, or change camera settings (or type)

hope you find a way around it. that really sounds hassle for a project.
