Hi all hope your haveing a good day right i want to make edible a hair object i know how to make a Opolygon object edible as in the script below what do i need to do to change it to make hair object edible cheers in advance. 
 
def MakeEditable(op) :
 
  if (not op) | op.CheckType(c4d.Opolygon) | op.CheckType(c4d.Ospline) : return op
    op = [op.GetClone()]
  doc = c4d.documents.BaseDocument()
  doc.InsertObject(op[0],None,None)
  op = c4d.utils.SendModelingCommand(
                            command = c4d.MCOMMAND_MAKEEDITABLE,
                            list = op,
                            mode = c4d.MODELINGCOMMANDMODE_EDGESELECTION,

  Thank you Ray.

The hair ID's are found in: ..\..\..\..\modules\hair\res\description\ohair.h
Grab your hair object like any other object. Then use those ID's to change the attributes of the hair object as desired.

import c4d  
from c4d import utils  
  
def main() :  
  
  obj = doc.GetActiveObject() #Your hair object  
  
  obj[c4d.HAIRSTYLE_GENERATE] = c4d.HAIRSTYLE_GENERATE_SPLINE  #Use which option you want  
  bc = c4d.BaseContainer()  
  convert = utils.SendModelingCommand(c4d.MCOMMAND_MAKEEDITABLE, list = [obj], mode = c4d.MODIFY_ALL, bc=bc, doc = doc)  
  doc.InsertObject(convert[0])  
  c4d.EventAdd()

Hi ScottA thank you for your reply it works great on a preprepare hair object in cinama but when i generate the hair object in python its not working and use the script below is the one im trying to get it to work with any ideals cheers bud.
 
def main() :
  
             
      c4d.CallCommand(1018401) # Add Hair
      Cube= doc.SearchObject("Cube")
      obj = doc.SearchObject("Hair")
      obj[c4d.HAIRSTYLE_LINK]= Cube
      obj[c4d.HAIRSTYLE_INSTANCE_LINK]= Cube   #Puts the INSTANCE into the hair's link field         
      obj()[c4d.HAIRSTYLE_GENERATE]=6        
 
        obj[c4d.HAIRSTYLE_GENERATE] = c4d.HAIRSTYLE_GENERATE_POLYGONS_INSTANCE   
      bc = c4d.BaseContainer()
      c4d.EventAdd()  
      convert = utils.SendModelingCommand(c4d.MCOMMAND_MAKEEDITABLE,
                  list = [obj],

Give this a try:

from c4d import utils  
def main() :      
               
  obj = doc.GetActiveObject()      #The object you want to add the hair on

  #Change the "Generate" option to "instance" mode  
  hair[c4d.HAIRSTYLE_GENERATE]=c4d.HAIRSTYLE_GENERATE_POLYGONS_INSTANCE

  hair[c4d.HAIRSTYLE_INSTANCE_LINK]= Cube

Generating hairs can take a long time. Depending on how many you're generating.
It might be bad practice to do this kind of thing from a script. So be careful with how many hairs you generate.

Using Sleep() & DrawViews() like I did in this case lets C4D sort of catch it's breath for a second. And get caught with all of the changes that happened.
But it's a terrible hack...Not something I'd want to use a lot.
There might be a better(safer) way to make the script pause and catch up.

  The line of script add was
 
hair[c4d.HAIRSTYLE_LINK]= Cube
 
 Once again ScottA great job.

You're welcome.

Just don't use it in anything you sell, or make for other people.
Not because of credit issues.. But because using Sleep() like that is probably a bad idea. And can easily lead to crashes.
