To explain myself better I share two images, the first is the cxr saved during the first rendering phase, and as you will notice the lighting is correct, obviously there is still a lot of noise, the second is the cxr file after resuming the rendering, the light sources seem to no longer work, the image is practically in the dark.
Sorry if I only shared a detail but unfortunately I can't share the whole image.
I hope to resolve this issue within the day, unfortunately I have delivery times to respect.
