Thanks, I'll give it a go!

I have/own standalone license of Octane 3.x installed. I installed the OctaneRender to Modo Demo and upon startup of MODO, get:

1) ERROR: Detected the demo version of the plugin but the commercial version of octane.dll.

a) So I deactivate the standalone version, close MODO, delete my modo config ...
