Just testing out Cycles, just recalled some ways to speed up render so posting.
Maybe you guys know it already…
(save files first… not sure how it works in your computers)
This is mainly for the rendering via GPU.
Making Tile size bigger maybe 1/3 size of output size of render.
so if you are making 3000px x 3000px, setting tile to 1000 x 1000
(well you can try what works) Maybe going to far might lead to crashes, not tried that far yet…
For CPU not sure for RhinoCycles but there should be hyperthreading option probably somewhere for those CPU that can support it.
Anyway to speed up render:
- In Rhino Options -> Advanced -> type in “cycles” to filter cylces menu.
- In RhinoCycles.tilex & RhinoCycles.tiley change from 128 to something bigger.
I tested 128, 500, and 1000 and below are for time taken for 3 sampling.
(128) 18.56sec -> (500) 13.68sec -> not attached(1000) 8.95sec
Time is more than half, but I guess depends on the scene.
I also reduced bounces in the lighting and some others to speed up in general.
That’s just quality vs. speed, and your preference.
