Yes, same here KeeWe. It was just trial and error that finally made it work for me. But what I'm still not quite sure about is, if this is the 'official' way to get the render slave to work, because the Studio subscription is supposed to be its own thing, that doesn't come with the benefit of a free render slave.
Also, see Goldorak's earlier message where he mentions that currently they have bundled two full versions of Standalone in the Enterprise All-Access plan, in order to make network rendering work? Does that mean, I can run Octane on two machines at the same time apart from network rendering? I'll try that out this afternoon.
I'm in contact with Otoy's help line, who told me that they've got issues with the license server, which is why network rendering with the purchased version of Standalone (the one - I guess - we should actually use) doesn't work at the moment. They promised to let me know though, once it is fixed.
Either way, this is all a bit confusing at the moment.
