Octane renderer

and blender exporter 1.16
but when press render still image
get error
!i set octan path and project name and path…

Yes, you have to set the path to the octane.exe and setup a project name in the render settings panel.
It is may better to ask questions about octane in the octane forums, not many octane user here.
Latest exporter is 1.19.
