Re: symmetry in XSI 6.0

You can use a GATOR between your old model and the new modified mesh to transfert envelops and shapes.

Question on the "easy to workaround" thing.  We all know about the cloning thing when you're modelling.  But what about AFTER your model has been rigged and enveloped - the director has changes that will involve adding new polys, and posssibly changing the flow a bit.  Short of cutting your model in half, cloning it, making the changes, re-rigging and re-enveloping it - whats the best approach?  We can do tweaks in modelling mode while hte model is enveloped, but what if you need more drastic changes, and would like to use symmetry to cut down the workload?
