[Closed] Convert UVW code to meshOp.setMapVert, meshop.setMapFace

I have made a script that is working now very well – It applies a certain type of UVW map to every element of an editable poly. But If the object is big (has many elements) then the script is taking to long to apply an UVW map to every element and to collapse.

Please help to convert the code from using UVW map modifier to smth like meshOp.setMapVert, meshop.setMapFace.

I have never used them and I don’t understand how it works from autodesk help.

at the moment I have

fn collectVertElements node = if iskindof node PolyMeshObject or iskindof node Editable_Poly do
 (
 	getelement = polyop.getelementsusingface 
 	elements = #()
 	faces = #{1..node.numfaces}
 	while not faces.isEmpty do 
 	for f in faces while
 	(
 		ee = getelement node f
 		faces -= ee
 		
 		append elements ee
 		off
 	)
 	do()
 	elements
 )
 
  fn polyVertsToMinmax poly verts ElDimension = if iskindof poly PolyMeshObject or iskindof poly Editable_Poly do
  (
 	 local bmin = [1e9,1e9,1e9], bmax = -[1e9,1e9,1e9]
 	 getpolyvert = polyop.getvert
 	 for v in verts do 
 	 (
 		 p = getpolyvert poly v
 		 for k=1 to 3 do
 		 (
 			 if p[k] < bmin[k] do bmin[k] = p[k]
 			 if p[k] > bmax[k] do bmax[k] = p[k]
 		 )
 	 )
 	if ElDimension == yes then 
 	--#([bmax.x-bmin.x,bmax.y-bmin.y,bmax.z-bmin.z], 6)
 	#(bmin,bmax)
 	else	
 		minmax bmin:bmin bmax:bmax
  )
 
  ee = collectVertElements $
  --print ee
  BminBmax = for e in ee collect polyVertsToMinmax $ (polyop.getvertsusingface $ e) yes
  --print bb
 

and here is a piece of code that I don’t understand how to convert to avoid collapsing:

	if (node.modifiers.count > 0) and isKindOf (local temp_mod = node.modifiers[1]) Uvwmap then --(classof node.modifiers[1] == Uvwmap) then
 	 for i = 1 to elements.count do
 	 (
 		maxOps.CollapseNodeTo node 1 true -- collapse		 
 		node.selectedFaces = elements[i]
 		max modify mode
 		subObjectLevel = 5
 				
 		local planeMap = Uvwmap()
 		planeMap.maptype = temp_mod.maptype
 		planeMap.length=temp_mod.length
 		planeMap.width=temp_mod.width
 		planeMap.height=temp_mod.height
 		planeMap.realWorldMapSize=temp_mod.realWorldMapSize
 		planeMap.mapChannel=temp_mod.mapChannel 
 		planeMap.axis=temp_mod.axis 
 		modPanel.addModToSelection planeMap
 		 
 		 
 		UVWa = #(0, 90, -90, 180)
 		rnd = random 1 4
 		UVWr = UVWa[rnd]
 		planeMap.gizmo.rotation = (angleaxis UVWr [0,0,1]) as quat 
 		planeMap.gizmo.pos += [random -rangex rangex, random -rangey rangey, random -rangez rangez] 
 		 
 	 )
