Hi, i have problem with cinema4d and Octane render 3.07 r2.
i have notebook with gtx 1650, windows 10 64 bit
so when i press render in octane, it displays text “there is no cuda device which is selected”
Then i go to octane settings and in the device i selected my gpu, then when press render botton nothing is change
and in settings gpu is unselected.

i upgrade nvidia drivers to last version but it still does work
