I think I found a bug. I have the latest version of the plugin "OctaneRender 3.00 beta 4 (3000015)"
The "Use modo resolution" isn't working anymore. If you click it, the resolution stays at 1500 by 1500. Even though I change the modo resolution. It works if I uncheck that and then type in the resolution in the Kernel Settings. Very frustrating. Why would that change from one plugin to the next? Not saying you did it on purpose, more of just venting frustration of sending something to the client that ended up being lower res then requested.
Hope it gets fixed, but at least I know I can work around.
Thanks!
