Hi All and thank you for your reply.
Attached you can find a very basic scene (Sorry but I haven't managed to make the video yet).
If i start the interactive render and try, for example, to change the seed of the noise, already it is beginning to slow down.
If I obviously try to do it with a more complex scene (e.g., trees, bushes, etc.), it becomes super slow.
We have different workstations in the office but for this test i used this one with Cinema 4d R25 and Corona 9 Hotfix 1:
- 3970X 32 core
- 128 gb of ram
- 2x Nvidia quadro A5000 34gb Vram
- Windows 10 professional
Thank you so much
