SceneCaptureComponent2D not rendering light correctrly

[Kostuk93]

Hello, I’m making the multiplayer lobby for my game and I do it this way:
I spawn an actor and this actor has SceneCaptureComponent2D inside itself. And thelobby widget is using the texture of render target, that capture component is using.

So long story short: I made the specific lightroom for the actor:

But capture component doesn’t seem to work with it well:

But when I turn ON the Global Illumination in Post Process Volume it starts to work properly:

But the probplem is that this feature is heavily dropping FPS if there are more clients (with 3-4 it’s just unbearable). I can’t use it.
Also I managed to render it at least poorly lighted before I deleted all the light and made that lightroom.

And also do you guys have any ideas how to get rid of that noise in render?

Ok, I figured out that I Had to build the lights in scene.
Now I’m getting the next issue. SceneCapture only registers red channel:

This is how they suppose to look (but without background and less bright):

What can be wrong?
