Detuch elements by ID in 3ds max

Nels

Hi, I have a script in 3ds max that detaches model elements by ID, but it doesn't work when I select multiple objects, can anybody fix this script?

Thanks in advance!

Here's the script

(

for obj in selection do

macros.run "Modifier Stack" "Convert_to_Poly"

(

(

local MatID = 1

    

while (polyop.getNumFaces $ > 0) do

    (

    $.selectByMaterial MatID

    polyList = polyop.getFaceSelection $

    

    if (polyList.count > 0) do

        (

        newName = (uniquename "DetachedObject")

        polyOp.detachfaces $ polyList delete:true asnode:true name:newName    

        )

    MatID += 1

    )

)

)

)

Klunk

macroScript explode_by_matid 
			category:"Claudes Utils" 
			tooltip:"explode by material id" 
			ButtonText:"explode"
			icon:#("Standard_Modifiers", 22)
(
	fn explode_by_matid poly del_original = 
	(
		matids = #{};
		for f = 1 to poly.numfaces do matids[polyop.getFaceMatID poly f] = true;

		for matid in matids do
		(	
			poly.selectByMaterial matid;
			detach_faces = polyop.getFacesByFlag poly 1;

			newName = uniquename "DetachedObject";
			polyOp.detachfaces poly detach_faces delete:true asnode:true name:newName    	
		)
		if del_original then delete poly;
	)	

	on execute do 
	(
		selected_objs = $selection as array
		clearNodeSelection  redraw:false;
		for obj in selected_objs where canconvertto obj Editable_Poly do
		(
			poly = convertToPoly obj;
			explode_by_matid poly true;
		)
	)
	
	on isEnabled do $selection.count > 0;	
)
