Does anybody here knows, a way to find animated plugs with the the python API. The python API 1.0's MAnimUtil gives me a memory leak report "swig/python detected a memory leak of type 'MAnimUtil *', no destructor found." then crushes maya.

Could you post an example of what you are currently trying?

* fin(d)AnimatedPlugs(path, plugs)

Also I’d suggest to use python API 2.0, but I didn’t find an equivalent to findAnimatedPlugs() after a quick lookup

Is there as safe way to query keyed attributes, doesnt have to be with the MAnimUtil in maya api 2.0?

A plug connected to an animCurve* node could be considered "keyed". So what you could do is look for whether something is connected to the plug, and whether the connected node is an animation curve.

I was trying to avoid doing that. When I query the plugs manually, the whole code structure fall apart. It doesnt spit out any errors and it runs smoothly but it does do the absolute job, it works here and there.

The tool sets transforms then creates the animation curves to connect to the other identical control. But if i use the quering of plugs over iteration or just one on one animation transfer it avoids the setting of transforms, sometimes other information from the old animation curve. When I was using the AnimUtil it run fine but when it came to complex rigs it crushes maya due to the memory leak.
