It does work in creating the actual topology yes. Thank you for that. For the material transfer I think there is a limitation in that you cannot access material data in ICE unless it has been set by ICE (At least I couldn't do it). Therefore you probably have to deploy an ICETree to each instance master setting the materialID and use that back in the created mesh to reassign the materials.
I think this is a good exercise for writing a first C++ plugin for me and see how far I can get ;) -------- Original-Nachricht -------- > Datum: Thu, 12 Jul 2012 10:53:03 +0100 > Von: Ciaran Moloney <moloney.cia...@gmail.com> > An: softimage@listproc.autodesk.com > Betreff: Re: Freeze ICE tree to geometry? > Did Grahame's or my compound work for you?
