You need the render engine in order for the plugin to work - so Octane 2 will be required for the O2 version of the Poser plugin. You will be able to stay on 1.5 if you don't need any of the version 2 features.Initially I bought both Octane (which I sadly have yet to play with much) and of course your plugin. With respect to Octane 2, I really need only upgrade the plugin and still be in the rendering game, right (i.e. does your plugin embed the core engine)? Or does it require both purchases again?
