Hi,
I've tried most of the "tips" I could find on this forum.
Even turned the GI samples, AA settings, up.
Also turned the Receive Shadows from surfaces on but nothing seems to make this go away.
Please check the attached "Test.mp4" file.
Check the dark side of the canyon wall, (left side of the image) lots of flashing.
On the right side, there are also a lot of flickering on some areas.
The render settings (you can download the attached scene and check):
Detail 7.5
AA - 4
GI - Write / read cache file (to test render you must turn GI settings to "NO GI Cache file" since I can't send the GI cached files - too big)
GI cache detail - 4
GI sample quality - 4
Any ideas?
I uploaded the small Test.mp4 and the scene for the ones interested on make some tests.
One test you can do right away if, go to frame 25 and do a render, all seems nice (on the left canyon rocky wall), now, step to frame 27 and render, the bright areas appear right away.
Cheers.
