Submitted by ratatouille on Sun, 2019-01-06 03:15

Hello,
i need to do select objects which has polygons of no smoothing group.
and im very noob in maxscript.

fn selectFacesWithNoSG theObject =
(
polyOp.setFaceSelection theObject (for f = 1 to polyop.getNumFaces theObject where polyop.getFaceSmoothGroup theObject f == 0 collect f)
)<code>
 
I dont know why its not working..
thank you in advance.

This works for me:

(
	obj = selection[1]
	facesBA = #{1..(polyop.GetNumFaces obj)}
	noSMGFacesArr = for f in facesBA where (polyop.getFaceSmoothGroup obj f) == 0 collect f
	if noSMGFacesArr.count != 0 do
		polyop.setFaceSelection obj noSMGFacesArr
	redrawViews()
)

@miauu:
I searched exactly such feature - to check if all polygons has smooth groups before export. Work good in 2020. Thanks :)

he needs to select objects not faces ;)

NodesWithNoSGfaces = for obj in selection where canConvertTo obj Editable_mesh collect
(
	local found = false
	local tri = snapshotAsMesh obj
 
	for f=1 to tri.numfaces while not found where getFaceSmoothGroup tri f == 0 do
	(
		found = true
	)
 
	free tri
 
	if found then obj else dontCollect	
)
 
select NodesWithNoSGfaces
