I'm trying to import obj files one for each frame, and add PLA keyframes in C4D, but am not finding anyway to do it using python.  Is this even the right way to approach this problem?

I'm using C4D R12, trying to import cloth animation from massive.

So after three days of pain and suffering through bad docs and C++ decoding, I have a python solution.

import c4d
from c4d import utils
import os

DEBUG = True
BUILDFLAGS_0 = 0

def main() :
    '''Updates an objects keyframes for all frames'''

#get the object to animate
    obj = doc.SearchObject('Cube')

#get the pla track Description id
    id = c4d.DescID(c4d.DescLevel(c4d.CTpla, c4d.CTpla, 0))

# check if track already exist

plaTrack = obj.FindTrack(id)

if plaTrack == None:

#Create the pla track
    plaTrack = c4d.CTrack(obj, id)
    obj.InsertTrackSorted(plaTrack)

else:

plaTrack.FlushKeys()

ctime = doc.GetTime() #save current time

fps = doc.GetFps()
    start = doc.GetMinTime().GetFrame(fps)  #set min time
    until  = doc.GetMaxTime().GetFrame(fps) #set max time

#get the plaTrack curve
    myCurve = plaTrack.GetCurve()

#setup SendModelingCommand base container
    settings = c4d.BaseContainer()
    settings.SetBool(c4d.MDATA_CURRENTSTATETOOBJECT_INHERITANCE, True)
    settings.SetBool(c4d.MDATA_CURRENTSTATETOOBJECT_KEEPANIMATION, False);

# loop thru each frame
    for f in xrange(start, until) :

#set the next frame
        time = c4d.BaseTime(f, fps)
        doc.SetTime(time)
        doc.ExecutePasses(None, True, True, True, BUILDFLAGS_0);

#update timeline
        c4d.GeSyncMessage(c4d.EVMSG_TIMECHANGED)

#create new object
        newobjList = utils.SendModelingCommand(
                            command = c4d.MCOMMAND_CURRENTSTATETOOBJECT,
                            list= [obj],
                            mode=c4d.MODELINGCOMMANDMODE_ALL,     # mode
                            bc=settings,
                            doc = doc)

newObj = newobjList[0]

if newObj != None:

#get the points from the new object
            points = newObj.GetAllPoints()

#add the key frame
            dictKey = myCurve.AddKey(time)
            key = dictKey["key"]

#modify points for current frame
            points[3].x = points[3].x + 25.0
            newObj.SetAllPoints(points)
            newObj.Message(c4d.MSG_UPDATE)

#sync key frame with point data
            fillSuccess = plaTrack.FillKey(doc,newObj,key)
            if fillSuccess == False:
                print('Fill key failed for frame {0}'.format(f))

Thanks for posting your solution! I hope more people would do it
I know it can be frustrating at times, but the end result is worth it.
