Firefly in render

[jrcenator]

Hi, what is the cause of these firefly?

I'm using PT+HD

[Polymax]

Whta scene lighting? What material of the floor?

[jrcenator]

For lighting, i used corona sun via daylight sistem.
I attached the ss for wood material and sun setting

Do you use twosided glass in windows?

[jrcenator]

I'm using hybrid mode for the glass material and the object had thickness

[Ondra]

try hiding the glass, if it helps

[jrcenator]

I attached image with glass hidden, still no change. Also included in the ss is my render setting

[jrcenator]

Found the problem. Before I used override background with HDR maps. Now I used only corona sky and the firefly is gone :)

Thanks for all the response
