Hello,
I have a mac with a intel (R) Iris(TM) Graphics 6, running on big sur.
I tried to install Octane X PR11 for C4D, but when I try to set the GPU in the setting, it doesn't stay on, and when I hit render, I get the "no selected graphic card" message.
Did I choose the wrong version ? If yes ...

fond it. but I have the same problem.
Focal Length 15, Sensor Size 74, same problem as mention. first frame ok, then second fall back to probably 15 / 52.5.
did you find a solution ?

Hi, Did you find a solution ? I have the same problem. Where are you supposed to find the sensor width ? Thanks !
