Thanks for the feedback, Shadowgin. :o)
After I ignored the installation tips (the R15 plug in works on my R16, the R16 does not, weird), Octane was running here but gave me an error message “There is no CUDA device which is selected…”, even the newest cuda software is installed here, and I even the plug in found my graphic card (settings).
I really try to get close to your set up, as my philosophy is, a problem not solved—comes back. ;o)
I hope the one machine rendering will be bearable and the result will pay for the patience :o)
Good luck with the project
