Quote from: Hannes on September 03, 2015, 03:46:32 amAt the moment I'm doing an animation with lots of Star Wars storm troopers and a bright imperial ship hovering in the air.The GI flicker in my test animations was tremendous! So I created a GI cache file. It's not flickering anymore, but it's more of a very obvious "GI-pumping" now. I created the GI cache with GISD on. I remember it was said, that GISD isn't recommended for animations, but as far as I know it was because of higher rendering times. It was also said that the GI cache file(s) don't include GISD, so I did a test sequence of about 80 frames with GISD unchecked with the previously created GI cache file.The pumping was still there, and render times were not much faster.So, did I forget something, or did I get something wrong? Is there any way to get rid of that ugly pumping?I have to say that the render quality may be a factor too. I'm using Detail/AA of 0.4/4 at the moment, which is not quite high, I know.The GI cache file is calculated for each single frame (with the actual rendering quality settings), and for rendering I used blend mode "interpolate" with 6 files to blend.Any suggestions?

Quote from: Matt on September 03, 2015, 08:53:25 pmThe quality settings of your GI cache are also important. "GI sample quality" especially. The default of 2 is quite low and will generate a lot of flicker. Cache file blending will smooth it out, but try to reduce it at the source if possible.Matt
