subdCollapse [-caching boolean] [-constructionHistory boolean] [-level int] [-name string] [-nodeState int] [-object boolean] [string]

subdCollapse is undoable, queryable, and editable.

This command converts a takes a subdivision surface, passed as the argument, and produces a subdivision surface with a number of hierarchy levels "removed". Returns the name of the subdivision surface created and optionally the DG node that does the conversion.

Return value

string[]The subd surface and optionally the dependency node name

In query mode, return type is based on queried flag.
