Hello Yafu! There’s some reasons why i didn’t use Cycles in this project:
1- My textures + Geometry wouldn’t fit in my GPU memory;
2- Cycles in CPU render mode is very slow.
3- I think octane has better materials, the way it scatters light through them looks a lot better to me.
4- Octane is fast as hell, I rendered this 4k image in only 1 hour. Cycles even in GPU render mode would take me at least 6 or 8 yours with the same rig.
That’s my reasons, but I love Cycles and I use it quite often.
