Thanks for everyone's help. I'm posting my updated class that is now working.
class Scene : public boost::enable_shared_from_this

void sendYourselfToPython()

try {
object ignored = exec(EXAMPLE_PY_FUNCTION, pyMainNamespace);

Yes, once you've exposed the class to Python, you can pass pointers to
Here's a really short example of what I don't understand. Basically I
can setup the python function to accept shared pointers, but can I
setup it to also use normal pointers? In the example code attached,
if I uncomment scene->sendYourselfToPython(); it fails because it's
using "this" as the scen

That's a pretty vague description of what you're doing, so it's hard to
say. I suggest you reduce your question to a minimal c
Well, right now I'm just passing "this" from inside the scene object,
so does that need to be wrapped in a shared pointer?

This is where I'm calling the function inside Scene, by the way, and
getting that error.
object processFileFunc = _pyMainModule.attr("MeshImporter").attr("processFile");
processFileFunc(this, fileName); // right here, where the python func
takes a scene object and filename
I haven't touched this

So is this all I really need for the mapping then? I'm getting an
