Flickering GI lumen from emissive material

[Dead_Morose]

After restarting project i got this bug. Earlier i had not this bug.

Lumen setting:

I tried changing all the settings and nothing helps.

At the lumen overview i have flickering too.

I want to draw your attention to the fact that previously everything worked well.

At different level in the same project all work well too.

Try increasing maxframes accumulation to .25 in the Lumen Cvars. Probe one specifically

This slightly reduced the effect, but did not remove it.

Figured it out.
Accidentally.
Due to the fact that I used nDisplay (херня for rendering multiple screens), the lumen was incorrectly considered. More precisely, each frame was recalculated for each screen, and since there is formally one cache, each calculation was overwritten by another. It helped to remove NDisplayRenderActor, wait for the lumen calculation and return it back. How to do this during rendering - I do not know.
This is basically a “solution”, but in fact - no.

PS. …checked it out. Each camera from NDIsplay uses its own lumen cache during rendering, which is why this bug is only in the editor
