Auto Volumetrics creates unwanted dark circle
Recently I've been trying to improve the lighting in my virtual scenes using auto volumetrics, and overall I really like the effect but I've run into an issue twice now where it creates a dark circle. Previously I simply changed the light position such that the dark spot would remain hidden by a dark part of the scene, but in this case I have the position exactly where I want it for the rays to settle where I want them, so this isn't an option.
Here is a comparison of my scene with auto volumetrics activated
And also without volumetrics
You can see that the dark circle in the middle is removed once I turn off the effect. (It actually still remains a bit because I'm using the effect on two different grade layers to exaggerate the beams, and here I only turned off one of them)
Any suggestions? Thank you in advance!
