You made me google "balsamic crashes" :D
It does not even crash, but just wondering why Maya or Computers in general seem to exert that behavior at times.
Like when I select 100k faces it does not take 2 times as long as selecting 50k faces but say 10 times as long.
All while the the Computer seems idle.
Not that I could do anything about it anyways :D
Edit: There seems to be a way via BE_VDBAttributeFromVDB:
Will give it a try....
