Maya looks up for Houdini start up and then connects its python to Houdini's automatically. Thanks to that, in this video, I create a "live connected" camera and I can also send meshes directly from Maya to Houdini ( and vise versa ).
This needs the rpyc module for Python 2.7 ( it is also included with Houdini ), you can downloaded it at this adress : http://rpyc.readthedocs.org/en/latest/
Here is the source code for the connection Maya => Houdini. It must be saved in the scripts folder of maya and used as followed from a Python shelf tool:
import MayaModule
ui = MayaModule.MayaConnectionUI()
ui.show()
You can copy the icons green_light.png and red_light.png in a folder "icons" saved in the same place as the python file.
On the Houdini side, you must have a Python file called "123.py" (or hescape.py if you use Houdini Escape ) withthese two lines of code in it:
import hrpyc
server = hrpyc.start_server(port=18812)
