There is no complete documentation on this (since you are the first to ask how to do this). However, you can access the plugin data via http://poserphysics.blogspot.com.au/2014/12/clearing-all-octanerender-for-poser-data.html. There is also an Octane plugin python wrapper - which is loosely documented at https://docs.otoy.com/manuals/products/rhino/v3/python-interface/. The Poser plugin python wrapper has some slightly different method names to the Rhino wrapper, but it gives you an idea what is possible. The Rhino wrapper python code is attached - which will give you an idea of what is possible - however the function name calls and dll name is slightly different, so you will need to quiz the Poser plugin OctaneWrapper.pyc import for the specifics. Obviously you'll need some good python skills to achieve all this.Is there a documentation available on the python api used to control the octane plugin from Poser?
