Octane vs Cycles

Decided to test Cycles- against Octane, so created this simple scene.

The setup is almost exactly the same (I could've done more but..). The main differences is the colors of the light (Blackbody in Octane, color in Cycles [let's hope for bb in the future]).

I tried to keep everything else the same, but it's not easy, Example, for glass in Octane (specular) you have IoR, reflection and roughness. In Cycles you have roughness and "fresnel" (basically IoR + Reflection). So in Cycles you need to choose a value that looks the best, instead of choosing a value you know is physically correct.

I also had a problem with DoF in Cycles (with a lens radius of just 0.01, the DoF was way to shallow), which is why it's all in focus in the Cycles-render.

(Focal-length in Blender 80mm, FoV in Octane: 14.7)

Also notable that Cycles seems to give renders with higher saturation (as "default").


But Cycles is still Alpha, and I do believe it can be really great (it's already pretty good).


My final thoughts on these two renders is:

The Octane-render is more realistic, but the Cycles-render is a bit more artistically appealing. (I think the reflection in the "table" looks much better in Cycles, but with this light-setup it's more realistic in Octane [I actually tried to reproduce it in Octane, but couldn't]).


What do you think?
