Here on a simple scene it works ok...(cylinder enveloped to a 2-bone chain)
logmessage (selection(0).envelopes(0).deformers.getAsText()) // INFO : cylinder,bone,bone1,eff funny thing is the cylinder itself got logged, also the effector that was not picked as deformer. 2012/12/18 Adam Sale <[email protected]> > envelope > Select deformer from envelope? > > > On Mon, Dec 17, 2012 at 10:26 PM, Matt Lind <[email protected]>wrote: > >> We are trying to upgrade from Softimage 7.5 to Softimage 2013 SP1 and ran >> into a speed bump during testing.**** >> >> ** ** >> >> Our workflow for character work is to create a master character rig which >> contains the skeleton and body (flesh) geometry.
