I would like to inform you I started your plugin review here:

A new article will come soon and it will be published on our most important CG server www.grafika.cz as well
I´m really happy I got a suitable GPU and have an opportunity to test it.
If I can, here is my wish list, i hope I´m not wrong,just I´m not an Octane expert

If you turn off a color channel, it activates it instead
If you place a texture load an effect over the texture, it´ s not automatically loaded inside (sometimes, several shaders support the feature) ImageTexture is a good example.
IS possible to change a default/turn off Environment. Just stay pure black?
Is possible to export a whole scene to StandAlone? It exports materials only to me
No worries, I did not mention it
