Lumen not changing increasing Final Gather!

Development Rendering
1

I’m trying to remove flickering from Lumen caused by settings.
I’m increasing final gather to 4 eevn 8 in PostProcess Global Illumination with no effect!!
Even settings everything to EPIC nothing happens.
I have a RTX4070,
light are coming from emissive materials only.
What do I do wrong please?

At the moment, that’s just Lumen :sunglasses:

If you want to get rid of the flickering, ray tracing would probably do the trick.

no but one second,

raytrace is one thing, Lumen is another one.
Raytrace is on in my project

However there is no way to fix it??

I don’t know that much about it, but it seems to one or the other

5

ok and so, how can i fix it ?

Did you turn off Lumen?

I Did and the problem still persists!
It’s happening only with emissive materials. I have to set a light in addition to the emissive material to avoid (or mask) the issue, what you think?

Strange, it should be rock solid with RT.

I do know that Epic are phasing out RT in favor of Lumen, so presumably things are going to improve. It’s very noticeable at the moment…

exactly… however at the moment I see that implementing light in the scene in addition to the emissive material the problem is going to be at least masked.
I Have to try with low light emission that i need it too… finger cross

Now I’m wondering if RT doesn’t include emissive…
