Hi Paride,
when i render or open octane viewport some objects are in front like the wheel Why. They are all set as movable proxies. Octane is not updating something
before in octane 4 and max 2018 we never had this problem not sure if it is max or octane we use craft animation for car animation
UPDATE:
When I convert these instanced wheels, eyes to copies the problems gets fixed. So the first wheel works fine all other instanced wheels dont move until they get converted to copies. It looks like octane bug.
Please see attached video Copies move and instances dont update
I hope they can fix this bug and network rendering asap
