Next thing to try is to reboot and try rendering again. If that does not fix the issue - then it looks like one of your plugins is effecting the Octane plugin. Do you have all those plugins also in 701? Does disabling all plugins other than the Octane plugin fix the problem?Yes. I already deleted 801 config file.
but nothing changes.
My all Plug in is....
Another question - have you installed the Octane plugin ONCE and are running that one installation on both Modo 701 and 801? Or has the plugin been installed into a different location for each of the two Modo versions?
