2 issues with auto volumetrics
I am trying to use the auto volumetrics effect to make light rays that come through clouds and trees, but I have 2 issues with the effect, and I was wondering if I could get tips on how to fix, or at least minimize these issues. Here is a preview of one clip I edited using the auto volumetrics effect:
1) When I use the effect, it creates a dark spot near the location that I use as the light source position (although not at the exact location). It's not very noticeable in screenshots, but you should be able to see it in this preview. It starts on the left side of the screen in this clip, and then moves over to the right.
Side note: the effect also creates a dark circle, but this is not as serious of an issue as it sort of looks like a lens flare so I'm more willing to keep it if necessary.
2) The light rays from the volumetrics effect have a random flicker that I can't get rid of. You can see it if you look at the rays that hit the islands on the sides of the scene. This is not as much of an issue as the dark spot, but it still does not make any sense to me, and I would like to be able to get rid of it if I could.
Is there anyone who could explain to me the cause of these issues, and how to fix them? I would greatly appreciate it!
