Re: Weight transfer question
Yeah this should be a part of a standard rigging workflow. It has been long since I rigged, but when I was doing it I always kept nulls as deformers constrained to other parts of the rig. This way you always have a clean "layer" in your rig with just meshes and deformers. It then becomes very easy to plot all the deformer nulls and remove all constraints. The rig is then simply meshes with deformer having animation on them. It specially helps to export to other DCC apps without any pains.

Re: Weight transfer question
I have personally started following this policy of enveloping to nulls which I constrain to things because I've found if I change my mind about a setup I can always reparent some nulls and it's less work than removing deformers or transplanting weighting.

Re: Weight transfer question
Cheers Ronald. I may be wrong.. but I think it would be better if the new nulls created became part of the character/scene rather than generated every time character export to engine.

Re: Weight transfer question
Couldn't you just give the Nulls identical names to the deformers, and then simply load a previously saved envelope ? - Ronald On Fri, Aug 17, 2012 at 1:14 PM, Kris Kelly wrote: > Hi Guys, > > > Has anyone any experience in transfering the weight map properties of a > deformer to a another object (null) using python?? > > > I am exporting animation and mesh to a Our Engine on the iPad. > > > Created this so far, > > > root = Application.ActiveProject.ActiveScene.Root; > > for deformer in Application.Selection: > nullName = deformer.Name > null = root.AddNull( nullName + "_bn" ) > null.kinematics.AddConstraint( "pose", deformer, 0) > > > > At the moment the character is enveloped to the Deformers and weights have > been painted with great detail.

Re: Weight transfer question
Thanks for this! seems a like a perfect base. Kris On 17 Aug 2012, at 13:02, Alok Gandhi wrote: > There is a old script of mine, which I posted here: > > http://groups.google.com/group/xsi_list/browse_thread/thread/f64374f1bae51ed2/9224fcfceddd0c48?lnk=gst&q=alok+gandhi#9224fcfceddd0c48
