I've never been able to animate in scenes with Radiosity because the
lighting differs from one frame to the next. I've tried all of the usual
things of upping the various quality values but the flicker never leaves.
Is it best to just keep radiosity out of Anims?

This is 'by-design'...

Yes.
At best, you can try photons...

No. Have you tried to save the radiosity data and then reusing them
instead of calculating them for each frame?
Just my 2 eurocents,

I'm creating a walkthrough by animating my camera. I'm using the
ClockModifier includes
http://www.geocities.com/SiliconValley/Lakes/1434/clockmod.html
and adding these lines to my povray.ini file
Initial_Frame = 1
Final_Frame = 250
I know how to save my radiosity solution with
save_file "file_name"
but then how is this reloaded for each subsequent image rendered?
TIA
Russ

Make some still shots from every place in your walkthrough. Save the
radiosity data of all these shots and copy them all into one file. Now
you can use this file for evey frame. POVRay will select the right data.
Hope that helps.
So long,
Bonsai

Or: render the animation and save the radiosity from every frame, or every
few frames (depending on the speed your camera is moving, and how the
scenery changes), and stitch all that together for a second render pass...
Might be easier than figuring where to best place the camera to collect the
required radiosity data.

If the scene isn't changing at all, then saving and loading radiosity data
is exactly what you want. The parts of the scene which were visible in the
previous frame will already have their radiosity set up, and the parts which
are newly visible will have their radiosity calculated. This avoids a lot of
recalculation, and areas that were visible in the last frame should be left
mostly unchanged.

#if (frame_number > 0)
load_file "filename"
#end
save_file "filename"
I guess I should say that I've never tried this method, but in theory it
should work.
