artUserPaintCtx is undoable, queryable, and editable.

This is a context command to set the flags on the artAttrContext, which is the base context for attribute painting operations. All commands require the name of the context as the last argument as this provides the name of the context to create, edit or query.

This command executes a scriptable paint (Maya Artisan). It allows the user to apply mel commands/scripts to modify cvs' attributes for all cvs under the paint brush.

Return value

stringThe name of the context created.

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