Hi,
if you have installed OctaneRender for Blender, and are getting this error
"Waiting for image" when you try to render or use Rendered Preview Mode,
please check that you have:
1. input your login info from your Octane Live Accounts, Octane Render Blender Plugin
(different from the StandAlone info)
2. You have the StandAlone license and it's activated...you cannot use OR4B without it.
If you still get the error, please post here. It happened to me and others here, but it's working fine now.
And if anyone else has something constructive to add, please do.
