Maybe adding support for an existing library like Alembic format would solve
this request and some others?
https://en.wikipedia.org/wiki/Alembic_%28Computer_Graphics%29
or micro poly tesselation and displacement at rendertime, renderman style? Does
Aqsis have it? as an open source example?
I don't know much about all these solutions but I would love to be able to do
exactly the same thing you request.
