When I shine a spotlight on a mesh with a small hole in it in a space with a VolumetricFog, the fog on the ray appears to move as shown in the image.
I would like to know how to stop this fog movement.
This is new for me as i haven’t had these problem before.
Try messing around with these two settings maybe that might help :-
and even if still doesn’t work then try switching on and off the volumetric settings in your spot light,
also if you are using HWRT try using cast ray traced shadows to enabled in your spotlight.
Thank you for your answer!
However, I could not improve it by the method.
that is partially temporal reprojection and jitter and the fact that it’s computing the fog in slices in a geometry shader. those are the relevant cvars you can try to change. figure out a combo that works.
doing foggy lasers (very thin light streaks) is a very borderline case for the engine either way, since volumetric fog is bound by a grid and it’s computationally expensive to march light pathes (especialy for this thin one) every frame.
an alternative would be to compute a “laser” geometry procedurally and fake the ray this way. cheap solution.
Thanks for the answer!
I will try cvars.
