Setting UI canvas to Screen Space - Camera will darken the UI elements

Greetings,

I’m running unity6 wiht HDRP, and having some issue with UIs.
All the UI elements in my canvas becomes darkened/greyed when changing from screen overlay to screen space camera. Here’s a pic:


I tried to change the screen space distance, the volume mask, and everything i could think of, but it’s just constantly darker for no apparent reason.

This is quite annoying since i can’t really highlight certain UI elements enough.
FYI i’m running 3 cameras, and the UI image is rendered seperately in the UI camera (and the last camera renders UIVFX on top of it), using UI in screen space kinda makes everything easier for this specific project.

And apparently i think there’s a solution i could change the UI back to overlay so it’s rendered properly, BUT, by that way i can’t get any VFX to render on top of it. And if i set the canvas to screen space-camera, i can properly do VFX on top, but everything is darkened. so i’m kinda locked in between.

May i ask if anyone has similar problems and if anyone does, is there’s a way to get the brightness fixed?
