Looking at the API docs, extendToShape() says it will fail if the transform has more than one immediate shape: http://help.autodesk.com/cloudhelp/2018/ENU/Maya-SDK/cpp_ref/class_m_dag_path.html#a658d9664035ff84ffefa217c0e45cc88
There looks to be 2 more calls that might suit your needs: MStatus extendToShapeDirectlyBelow( unsigned int index ) MStatus numberOfShapesDirectlyBelow( unsigned int & num ) const So you can check if the transform node has more than one shape, and get the exact shape index you are after. - Justin On Thu, Sep 20, 2018 at 9:29 AM miarmy <[email protected]> wrote: > hi! first, i write this code: > > MSelectionList selectionList; > MGlobal::getActiveSelectionList(selectionList); > //first selection : > MDagPath dag_path; > MItSelectionList kDagNodeSelectionList(selectionList, MFn::kDagNode); > > kDagNodeSelectionList.getDagPath(dag_path); > > MObject obj; > //get shape : > dag_path.extendToShape(); > obj = dag_path.node(); > MFnDependencyNode meshObj(obj); > > in transform node with one shape or mesh node, this code is true and > it Give us the only mesh, But if the transform node had more shape node, > How to find individual shapes? > > -- > You received this message because you are subscribed to the Google Groups > "Python Programming for Autodesk Maya" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > To view this discussion on the web visit > https://groups.google.com/d/msgid/python_inside_maya/30a38c5b-1526-48cb-860b-0f46d7708747%40googlegroups.com > <https://groups.google.com/d/msgid/python_inside_maya/30a38c5b-1526-48cb-860b-0f46d7708747%40googlegroups.com?utm_medium=email&utm_source=footer> > . > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "Python Programming for Autodesk Maya" group.
