I am now trying to get a nice effective workflow for renders because I now feel it takes a bit too much time but of course, it is all relative. Basically I am not great with making very photorealistic renders so far with great details so now that a render with an empty room with a wood floor + windows takes 38 minutes, I am slightly worried about how it would be if I add various materials etc. Hi! Thanks for this thread, I am also in this moment of not being sure if my render is optimized.
