Hi, I need some help.

I have corona sky+sun, I want to use hdri map as visible background, reflection and refraction. When i activate bloom and glare i get beautiful colored stars :-D And on one spot of the floor I even have NaN?

Am I doing something wrong? Is this an old technique? I'm using the latest daily build ( 9 daily Aug 30 2022) Cinema R21

Hi there, have you tried using the direct visibility overrides? My example is being lit by the sun/sky and I have a light mat (emit light unchecked) assigned to the direct visibility override. You could even add a Tonemapping shader to control the brightest of it if need be. I hope that helps.

I would suggest using a tonemapped image for the backround (tif/jpg/png) instead of using a HDR or EXR file...

Thanks guys, both options work fine. Konichowaa, your solution is better, I can see directly in the viewport and I can control the rotation in one place.
