Hello, who know why corona light noise?
first pictures have 10 pass, next have 2000 pass and looking good, but noise must go on 250-300 pass. Light - HDRI+corona light, corona light is main.
Third pictures looking good, and have only 300 pass. Light - HDRI+corona light, HDRI is main.
Thanks for help!
Hi, I do not understand the issue.
First picture is noise - the other ones look good. What is the difference between them? I do not understand the “Corona light is main”, “HDRI light is main” part. What does it mean?
Can you show some additional screenshots? How is the lighting made? The noisy image - what kinds of lights are you using? How many?
How can you expect anyone to help you with such little information? 
1st pictures is 10 passes, 2nd pictures 2000 passes. I say this, because noise go, but very long time. HDRI light is main or Corona light is main - is main lighting in the scene.
Can you send us the scene? We would inspect it.
send a personal message, because is commercial work
The problem was that the light was shining at the ceiling. Thanks to the Corona team!
