Hi,Juanjo
I always have a litte trouble when I use IPR rendering.
That make the Houdini's operation be in slack and I can not operate node network and viewport comfortably.
I think it would be more beneficial if you could solve it in the future.
and I think the OC plugin for Cinema 4D may have a good operated experience when IPR rendering.
Those is some advices in using experience for OC in Houdini.
I will be more than happy to see improvements in this regard.
Sincerely yours
-Edison
