Getting transform node name from deformer

[user_deleted]

Hello
I need to get full dagpath to currently deformed object (shape or transform) from inside deformer() or compute() method of MPxDeformerNode. I know this is heavy break of maya rules, but I'm willing to take a risk

Can anybody come up with a trick ?
For a case where there's only one deformer in history, I can get input mesh with this code (more or less):

    MPlug outputPlug(thisMObject(), outputGeom);
    outputPlug.selectAncestorLogicalIndex(geomIndex);
    MPlugArray outputs_plugArr;
    outputPlug.connectedTo(outputs_plugArr, false, true);
    outputPlug =  outputs_plugArr[0];
    MFnDependencyNode mesh_dn(outputPlug.node());

This breaks as soon as I have smth else in hostory.
Anyone? Joojaa ?

thanks!

Why? Wouldnt tis be dsmething thet you would connect as a input to your node.

This deformer is a cache reader - reads data from disk files, one file per frame per shape.

OK but still why isn't the target stored in a attribute of the node? This way  the user can decide to remap the data if they so wish. I dont think it the developers job to limit the use scenario. What you do is your setup command/template should handle the mapping. The nodes should not need to know this. Besides what if the user renames nodes?

I mean the GUI can handle this. the gui is part of the users experience as integral as the node, no need to push all of the problem to the node level. So when the user adds a node then the GUI handles setting the name of the target to said output say store it in a string attribute or array if your node handles many shapes.

Anyway you could do what you ask its just horribly inefficient. As far as i see there's also no need for such things.
