[Closed] PLEASE HELP!Detach by material ID without opening window for options

I hope that you have tested the script and with give settings it works for you.
Here is the same script that works with no UI.

/*
Detach by Material ID
Version: 2
by Jefferson Lim
Terabye Inc./ Shirogumi Inc.

[features]
Detach Polygons based on its Material ID
- works on a selection of objects
- Options to name detached objects
- material propagation
  - this will assign a corresponding material by id to the detached object

[usage]
1. select any number of objects
2. set the desired paramteters
3. optional: if you know the maximun number of ids the object has
   set the Max IDs to help speed up detachment.
4. press detach

[Internal Operations]
Procedure:
- object[s] is/are copied
- then collapsed to an editable poly
- faces are finally detached by material ID

Naming:
- "Numbered"
  - will creae numbered names
  - e.g. 0,1,2,3
  - preferable to use with the Prefix option checked
- "Bitmap Name"
  - if not diffuse bitmap found, it will use the material name
  - if no material applied, it will use the object's name
- "Material Name"
  - if no material applied, it will use the object's name
- "Object Name"
  - will create a unique name based on the object's name

Hello
I am trying to use it in this script so i can batch a whole bunch of files out

thePath = getSavePath()--get a path dialog to specify the path
if thePath != undefined do--if the user did not cancel
(
  theFiles = getFiles (thePath+"\\*.max") --collect all max files in the dir.
  for f in theFiles do-- go through all of them
  (
    loadMaxFile f--load the next file
 
-----------------------------------------------------------
-- MAKE SOME SCRIPTED CHANGES TO THE SCENE HERE...
-----------------------------------------------------------
 
  saveMaxFile f --save the file back to disk
  )--end f loop
  resetMaxFile #noPrompt --at the end, you can reset
)--end if

I try paste your code in the

-----------------------------------------------------------

but i get a

– Compile error: No outer local variable references permitted here: maxIds
– In line: for i in 1 to maxIds d

Please help somebody lol

Try with this:

I still get a
– Compile error: No outer local variable references permitted here: maxIds
– In line: for i in 1 to maxIds d

Replace maxIds with 99: for i in 1 to 99 do

working thanks alot agian

This is cleaner version:

(
	MeshopDetachFaces = meshop.detachFaces
	mapped fn SplitMeshByMaterialID Obj =
	(
		if
			isvalidnode Obj and
			(Mat = Obj.material) != undefined and
			classof Mat == Multimaterial and
			convertToMesh Obj != undefined
		do
		(
			Mesh = Obj.mesh
			FaceCount = Mesh.numfaces
			IDs = #()
			for i = 1 to FaceCount do appendifunique IDs (getFaceMatID Mesh i)
			for ID in IDs do
			(
				Faces = for i = 1 to FaceCount where getFaceMatID Mesh i == ID collect i
				NewObj = Editable_mesh()
				NewObj.transform = Obj.transform
				NewObj.mesh = MeshopDetachFaces Obj Faces delete:true asMesh:true
				NewObj.material = Mat[ID]
				NewObj.name = Mat[ID].name
				NewObj.wirecolor = random black white
				converttopoly NewObj
			)
			delete Obj
		)
	)
	if (Dir = getSavePath()) != undefined do
	(
		disablesceneredraw()
		for f in getFiles (Dir+"\\*.max") do
		(
			loadmaxfile f quiet:true
			undo off
			(
				SplitMeshByMaterialID (geometry as array)
			)
			savemaxfile f
		)
		enablesceneredraw()
		resetmaxfile #noprompt
		messagebox "Done."
	)
)

Thank you guys for this amazing script.
I have been for a long time looking for it.
I wanted to detach by id but instead of converting it into an editablepoly to do it into an editablemesh.
I just changed the “converttopoly NewObj” into “converttomesh NewObj”.

Anyway I am quite new on scripting and I have been trying to modify this script so it would work on a selected object on an opened 3dsmax file.
Could someone help me out here?

Thank you everyone!
