Would like to know what contributes to render speeds.
just seems that each time i do a render it gets slower and slower. i did one a few days back with a fairly detailed car and a victoria figure with SSS etc, rendering at 3840 x 2160 resolution and it was rendering at between 4 and 5 msamples/sec. this scene had 12 emitters in it.
i am currently rendering another image that is just a portrait on a textured background, portrait of the same figure mentioned above, with only 2 emitters, at 3000 x 2250 resolution. this one is only rendering at 1.5 msamples/sec
curious as to why a much simpler image is taking so much longer
