Did you try a lower threshold?

Hi! Micha
You can see in the enclosed attachment, either low threshold and intensity or high threshold and intensity looks the same

Right, since nearly all the intensity is below 1 you don’t get a glow. Try a lower intensity [EDIT: I mean threshold] than 1 and you will see a glow. The problem of your setup is that you don’t have intensive bright areas and it will work better and looks nicer if you have it.

Thank you! Micha
Still why there’s no difference between enabling and disabling the Bloom/Glare function?! And why there’s no reaction to my adjustment now?! Some aren’t giving the possibility to adjust at all.

Set the threshold below 1. 1 means pixel value 255 in 8bit. It looks like your image has no large dynamic. Maybe the brightest pixel is around 1 only. All pixel above the threshold will be processed. So, if you set it 0.1 than you should see an effect.

I habe no idea why it doesn’t work. You could try a fresh scene for a test.

Hi StarUpJewelry,

You can also save out the render as a .vrimg file and share it.
We’ll be able to see what is going on on our side.

Thank you in advance,
Konstantin
