Fire Flies and sky in Window

Hi

I have an issue with small white specks in the image at the meeting of ceiling and wall.
I am not getting any difference to the sky portal in the window, and the light outside is all white.
How do i get the image outside the window show?

Thank you.

Phil

Yup, most probably no thickness.
Btw, isn’t this improved in the newest builds? Got to check that.

I didn’t have this issue in very long time (but it was very common in alpha versions).

Thank you very much.
Yes the walls have no thickness.
And I will go through the tutorials.

Very much appreciated.

Easiest way would be to just slap on a shell modifier to the walls.
