Issues when the name argument of ViewerAppProxy.getattr is either getstate or setstate.
(I'm guessing deadlock is occurring. )

I solved it by throwing an exception for these names.

    def __getattr__(self, name):
        """Redirect method calls to the sub-process.

        Arguments:
            name {str} -- attribute name

        Returns:
            callable -- an application method wrapper
        """
        if name.startswith("__"):
            return self.__getattribute__(name)  # raise AttributeError

        def _send(*args, **kwargs):
            self._host_conn.send((name, args, kwargs))
            reply = self._host_conn.recv()
            if isinstance(reply, Exception):
                raise reply
            return reply

        return _send

Thanks for reading.

Hi, your interface with panda3d for robotics applications is promising!

I'm giving it a try but unfortunately the rendering is not as great as I would expect. As you can see on attached screenshot, there is annoying small artefacts on the body the robot. I tried with other robots, and sometimes it is even worse. On the contrary, some other rendering libraries do not produce such artefacts for the same models. Do you have any idea what I'm doing wrong ?

The RealSense example from the README page is blocking on:

ViewerAppProxy(mp.Process):25
reply = self._host_conn.recv()

It does not block if the Viewer is set to use an offline renderer.

macOS Catalina,
Python 3.7
Panda3d via pip (also happens via git install)

Some, but not all, other examples, block too, let me know if you would like me to expand on that.
