detachById (script to detach multimaterial objects)

uno script che divide in automatico gli oggetti con MultiMaterial in oggetti singoli, creando anche i materiali nuovi.

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

new version of this script modified by Juha Pyy:

now the script will not fail anymore if you select an object that is not multiobject.

This will allow to process objects in bulk, regardless if already processed or not.

thanks for the help Juha!

awesome,very helpful script,and this way even better

Just tried the updated script, and it looked like it was working, but I can’t see any textures in KOFlite as if it didn’t detach any?

copy the script in your 3dsmax script folder


-select all objects
-run the script



all object will be now detached, so you will not have anymore multimaterial objects

Andrea Lojelo wrote:all object will be now detached

Unless you run out of memory (like I always do)

well..in that case take a smaller group of object at a time!

A common method I use is:
1) open the layer window
2) create a new layer called Layer01 (this is automatically set as the default layer for the newly created objects)
3) select groups of objects and detach them.
NOTE: objects will move from default (original) layer to Layer01. default layer will always contain objects still to be detached.
4) save often in a new file. This will prevent to loose your work if max crashes (happen often if you don't have enough RAM, and you select too many objects.

work, I thought it locked up, while in 1 minute I did Deatch of 1580 items

Ciao ragazzi,
sono nuovo nel forum ,
sto cercando di importare in 3ds una pista per rf per alcuni esperimenti ,di conversione su un mio progetto
ma sono piuttosto asciutto di 3ds...
Da quello che ho capito lo scipt in oggetto dovrebbe separare gli oggetti e relativi submaterial in materiali standard , o sbaglio?
perche' sembra non creare nulla.
Seleziono gli oggetti... runno lo script , vedo che mi cambia il layer ma i submateriali rimangono tali e quali...che sbaglio???
Grazie e scusate...

Ciao Carlo,
purtroppo non so aiutarti su 3ds perché non l'ho mai usato. Io sto facendo un tracciato per netKar usando Blender (software FreeOpenSource) e anche se con una certa fatica si riesce a fare tutto (ci vuole pazienza...).
Il modo più rapido per convertire un file di rf in 3ds credo che sia usare 3DSimED. Puoi scaricare da qui -> http://www.sim-garage.co.uk/
una versione gratuita che dura 20 giorni, e se segui i tutorial che trovi in internet, o anche solo le istruzioni del progamma, vedrai che non ci vuole tantissimo.
Buon lavoro, spero che tu risolva
