Hi ,
I'm new with corona and I've got some probleme.
I'm using a corona sky as single map in the scene environnement tab .
And I woulk like to use a 2K hdri in reflexion override .but when I do that,there is some white dots ...
It's really better to use the hdri for reflexion,I tried to blur my hdri ,and nothing change ,and it's better if I can keep it without blur.

thanks

Answered in the support ticket.
Currently the only workaround I am aware of (but unfortunately far from perfect) is switching from an HDR to LDR image (e.g. JPG instead of HDRI).

Please let me know if you still experience any issues with environment overrides.

Thanks,

Has this fix also solved the adaptive light solver artifacts when using environment overrides or is just the fireflies issue?

Reflection Override - High Res Jpeg Pano, Adaptive Light Solver Ticked - Artifacts

Same as above but with Adaptive Light Solver Unticked - Artifacts gone.

I have just checked this and it is working fine now! Good catch!
I can't share the rendering right now because it was a user scene, but can come up with a similar comparison later, or feel free to try it yourself. :)
