polyNormal([caching=boolean], [constructionHistory=boolean],
[name=string], [nodeState=int], [normalMode=int])
Note: Strings representing object names and
arguments must be separated by commas. This is not depicted in the
synopsis.
polyNormal is undoable, queryable, and editable.
Control the normals of an object. This command works on faces or
polygonal objects.
In query mode, return type is based on queried flag.

This flag specifies the normal mode.
0: reverse; (This flag is being phased out and is included for
backwards compatibility only.)
1: propagate; (This flag is being phased out and is included for
backwards compatibility only.)
2: conform; (This flag is being phased out and is included for
backwards compatibility only.)
3: reverse and cut; Reverse the normal(s) on the selected face(s).
Selected faces are cut along their collective border and a new
shell is created. The normals in the new shell are reversed from
what they were before the action.
4: reverse and propagate; Reverse the normal(s) on the selected
face(s) and propagate this direction to all other faces in the
shell.
C: Default is 0 (reverse mode).
Q: When queried, this flag returns an int. |

Common flags |
name(n) |
string |
|
|
Give a name to the resulting node. |
|
constructionHistory(ch) |
boolean |
|
|
Turn the construction history on or off (where applicable). If
construction history is on then the corresponding node will be
inserted into the history chain for the mesh. If construction
history is off then the operation will be performed directly on the
object.
Note: If the object already has construction history then
this flag is ignored and the node will always be inserted into the
history chain. |
|
caching(cch) |
boolean |
|
|
Toggle caching for all attributes so that no recomputation is
needed |
|
nodeState(nds) |
int |
|
|
Defines how to evaluate the node.
- 0: Normal
- 1: PassThrough
- 2: Blocking
- 3: Internally disabled. Will return to Normal state when
enabled
- 4: Internally disabled. Will return to PassThrough state when
enabled
- 5: Internally disabled. Will return to Blocking state when
enabled
