@Pine722 When you say you deleted the Swarm directory I take it you just deleted the cache?
Crazy isnât it, you have decreasing shadows, and I want to get rid of them ( the followers!! ) ;_)
UPDATE:
Turned out I had a huge object (a skydome) in the scene which meant my entire level was in shadow. The confusing thing was that my dynamic shadows were only set to show in a relatively small distance from the camera, which gave the effect in the image. Setting this object to not render a shadow fixed the issue. I didnât have this issue in my 4.23 project which is a bit strange.
I had this issue out of nowhere when I tried coloring the skylight, and a shadow followed my camera. I didnât know what to do when I flicked the DirectionalLightâs âMobilityâ options between Movable, Static, or Stationary just to mess around with it. It removed the shadow and the issue was fixed. Maybe it reset the light or something when that option was switched, but shadow gone.
Honestly, I donât remember as itâs been a while, but it was probably the cache. If that wasnât it then, Iâd install a separate fresh version of the engine and delete the old swarm folder and copy the new swarm folder there. Hopefully you donât need to do that and the other posts offer more insight as to another solution. Iâd like to mention that whenever this bug occurred for me (it happened more than once), it was always completely random and did not happen after I specifically did anything to initiate it. If it was something I did then for some reason it would take a long time for it to appear.
I found what the problem is. Itâs in the directional light under Cascaded Shadow Maps. If you lower the value it will decrease the circle under the camera.
Nope, mine is on zero and I still get it, not even turning off shadow amount uinder sun and sky > directional light makes it all go awayâŚit has to be some bug ?
4.25.3 world comp terrain tiles.
I just had exactly the same problem, and it was Contact Shadow Length In World Space Units in my Directional Light that caused this behaviour.
I had the same issue. The sky dome had dynamic shadows turned on.
Delete the directional light and put a new one. If youâre using sky atmosphere. Set these settings in the new directional light.
Intensity = 1.0 lux
Atmosphere Sun Light = Checked
Cast Cloud Shadows = Checked

It because of skydome.
Un check cast shadow under lighting menu for skydome

so in my case my grass LODs were causing what I perceived as a shadow. Really what was happening is each successive LOD had a brighter overall color to it, so the circle closest to me was darkest, as though it was a shadow. The solution was to modify my LODs of course
I think this is to do with the ray traced shadow culling method, you can change it by using
r.RayTracing.Culling
with the following different values -
0: Culling disabled
1: Culling by distance and solid angle enabled. Only cull objects behind camera.
2: Culling by distance and solid angle enabled. Cull objects in front and behind camera.
3: Culling by distance OR solid angle enabled. Cull objects in front and behind camera.
and change the radius with
r.RayTracing.Culling.Radius
(find out the current value first with r.RayTracing.Culling.Radius ?) then enter in a new value
Had this issue using UE 5.3.2. In my case, Iâm using the cloud mask and object blueprints that are in the volumetric content folder. The cloud mask blueprint assigned a light function to my directional light and after removing it the circular shadow was gone.
