Hi everyone
Thank you for the tips and comments.
headoff, Cyanhide, yagi, yes, I also found it very noisy but it was not because I did not wait.
Rawalanche, I used the PT + PT for the outside and decided to use inside. I remade the image with HDcache mode and in less time produced a cleaner image.
The glass in the window are not enabled with caustics
Captain Obvious, I will improve on the next UV.
