This is my first test. I like the looks of it but given that this is the longest render i have had (excluding the animation) at 10m i am a little worried. Might have to cut back on some of the grass, seems a bit dense.
Renders can take a while even with less grass, This was done last year so i forget the setting sas i since changed GPU but it was a 3 hour render.
To be honest i think the grass is fine on yours mine needed to be more dense.
Yeah i decided to let it go whilst i went out to dinner. This is the result with less dense grass. Looks pretty good i think. This was 70 samples and took 2hr 55min using my Skylake I7 CPU. GPU doesnt have enough memory to do this stuff.
This is my initial render from the fluffy bunny in grass scene.
