PyMel is probably the most straightforward because you can use the API command influenceObjects and then read the weightList from an attribute. Using the API would be much faster if your rig is complex. Using cmds...I'm sure someone else knows how to get the influence objects from an attr. It's not something I've ever had to do.
Here's a PyMel example. With a couple of verts on a cylinder selected: import pymel.core as pm vert = pm.selected() mesh = vert.node() sc = mesh.listHistory(type='skinCluster') # Note this is not a great way to get skinClusters in general, but it works in simple situations. infs = sc.influenceObjects() print vert print mesh print sc vId = vert.currentItemIndex() print 'Vert:', vId for jId in xrange(sc.numInfluenceObjects()): print '\t', infs[jId], pm.getAttr(sc.weightList[vId].weights[jId]) prints pCylinderShape1.vtx[16:17] pCylinderShape1 skinCluster1 [nt.Joint(u'joint1'), nt.Joint(u'joint2'), nt.Joint(u'joint3'), nt.Joint(u 'joint4')] [0, 1, 2, 3] Vert: 16 joint1 0.0163752022203 joint2 0.933793770143 joint3 0.0495594248894 joint4 0.000271602747264 On Thursday, 12 April 2018 05:23:52 UTC+10, Eugene Flormata wrote: > > does anyone know if it's possible to find a bone from a mesh vertex in > python? > > I've found links to code for finding the polygons effected from a bone > > http://polycount.com/discussion/140109/melscript-python-selecting-influenced-polygons-from-a-joint > > but I'm having trouble finding the right command in reverse > maybe getting a list of bones affecting one vertex, or the bone with the > most weight > > > any help would be great > thanks! > -- You received this message because you are subscribed to the Google Groups "Python Programming for Autodesk Maya" group.
