Ray Tracing is beyond broken in 4.23

Oh, it’s a pitty. But you tried to explain it with images, videos and even sharing projects where you have prepared comparison/proof scenarios? For this kind of things, we must put the things as easy as we can. For example, with your only writen previous writes, I didn’t understand a lot… also, of course due to English is not my native language. But graphic information is the most valuable one!

Thank you!! I have sen it. This helps a lot to continue motivated and improved, more than any money :slight_smile:

I see… I haven’t still tried, but I wil do with your scene; I’m curious, but prbably we will always need square lights on windows, as maybe Global Illumination is too expensive and/or imprecise to bounce enough to illuminate an entire room indirectly.

You can share a project (to evidence one thing, as commented above) through Dropbox, Drive, or Mega, for example, sharing the generated link for an uploaded file (a compressed ZIP is the standard).

Regards!
