Some windows are so dark that the scene is not seen, this is because being unable to adjust the light from the Preview exposure you cannot understand how much light the scene represents. Furthermore, the use of OCIO, if activated, makes the scene even darker and the aforementioned problem complicates it.
I don't know if I'm wrong or if there really is a bug. Can you tell me (who downloaded this update) if you have the same problems or something else?
Thank you.
Ps: I will make other renders with ready-made files on TG 4.4.67 to see what happens. The rest seems to be working but I have yet to understand the situation.
