I’m late to the party, and I wish that this news didn’t exist… We were left without several talented Rhino developers in the recent years who made a huge impact on how the program evolved…
I would like to say THANK YOU for your great work, Nathan! 
Best of luck on your new job.
Rhino Cycles 8 integration has been really fantastic in genral. Made a big difference against Rhino 7. Raytraced is much slicker.
I’m not a known member here, but the announcement made me sad that we missed a capable developer in the forum.
Is there any hope you regret in the future and come back here again?
Of course I wish success for you in the new company
Thank you for your worthy efforts during these years 
Thank you for efforts and the support you gave here over the years Nathan! You will be missed! The best for you for the future!
Oh that’s a loss for Rhino but it sounds like a great opportunity for you.
Bringing Cycles to Rhino was a great idea, imo. I always had the feeling that the task of integrating Cycles was way too much work for one developer. I hope the Rhino team can compensate your departure and even hire more people to work on the rendering part.
I wish you all the success with your new work!
