so you need to reassign and preserve cluster info? there is a pretty
good chance any clusters made by the user will no longer be aligned
with your new data, so preserving the old data would be quite
difficult from my perspective. also any topological operators will
fail to be useful. from what i can gather from your task you will need
to remove the entire operator stack, storing supported ops, then
rebuild the mesh and re apply the operators. maybe you give some more
info about what you are trying to achieve?
I control both the old data and the new geom data. We are building a
preview mesh for a piece of external geometry, a.k.a. VRay Proxy /
Arnold Standin. The mesh is only useful in an interactive session - at
render time, we only use the external data. Users are not expected to
touch the mesh (it's not strictly forbidden, just doesn't make any
sense) but things like properties and overrides on the object should
stay put.
also the rendertree/materials will stay intact on the object, unless
you mean cluster/per face materials?
Exactly. I am looking to preserve user changes to cluster materials. I
can re-associate each face with a cluster, but need the clusters to stay
100% "as they were".
Thanks for helping!
