Hi ya !
I have a problem ! I have a master and 4 slaves all running 2.8 and CR17, I have an addon enabled called "toonkit" that uses OSL and that is installed on all machines aswell. So far all computers are synced and ready and can render from the master fine and dandy. My master and all slaves are set to cycles and have OSL enabled which is required for the toonkit addon . My problem is that crowd render will not render the toonkit shader when the slaves are enabled, however! it will render the toonkit shader when the master is ONLY selected . Also for the master only render I used the "render still" button in crowd render so the addon did the render. What do you think is happening?
