The UVW Mapping Clear
modifier is added to an object's modifier stack when you clear a
channel with the
Info utility. You can also add the modifier
explicitly by choosing it from the Modifier List.
To merge the results
of the deletion into the object's geometry, collapse the modifier
stack after deleting.
- Map Channel
Specifies the map channel
to clear. This is equivalent to clearing a specific channel in the
Channel Info utility. If the specified map channel doesn't exist,
the modifier has no effect.
