Niagara translucent particles dont recieve shadows at a distance from the camera

When moving away from the camera, Niagara transparent particles seems to be not shaded, even though there is a shadow at that point in space.


There is a screenshot illustrating the problem. All of it trail in shadow of cloud. On all other object this shadow works normally.


And there is material blueprint I using for this particles.

How can I solve this problem? May be some engine rendering or material settings? Looking for this for several days with no result. Thanks for attention

Are you using the Translucency volume? If so, does changing the value r.TranslucencyLightingVolumeInnerDistance change the point at which it stops receiving shadows?

No, I use “Volumetric NonDirectional” lighting mode.
It works. I set it to 1 500 000
But now i confused about what doing “r.TranslucencyLightingVolumeOuterDistance”?
Should I change it too?
