i'm facing a challenge and crunching trough it.  im a python starter but i like it.

What im trying to do is to replace all the textures paths in my scene (Materials setup : color channel -> multishader with 10 videoclips in it) in all Materials in the scenefile.

Here is the catch.
im replacing the low mp4 with an image sequence with it respectful folder. the thing that changes is basepath\imageseq_name\imageseq_name_00000.jpg where for every file there is another name (namex_00000.jpg in folder namex) which replaces basepath\allstuf\namex.mp4

Hope you understand what im trying to achieve.
For now i managed to do all the above except getin trough to multishader to replace the respective paths, otherwise im creating all new materials for every mp4 which gets replaced in multishader (located in color chan).

Here is my working script, please do not bithc me out im still learnin and its very fun, hope i can manage to do some more complex things in the future.

import c4d
from c4d import gui, bitmaps, documents, storage
import os
from os.path import basename, splitext
import re

print "------------ Starting"

def main() :
    myMaterials       = doc.GetAllTextures()
    fileExtensionWrong   = ".mp4"
    fileExtension   = "_00000.jpg"
    path1 = r'E:\global new\assests frames' #set ur paths
    path2 = r'E:\global new\assets' #set ur paths
    # insert the path to the directory of interest
    newPath = path1 + fileExtension
    #print newPath   
    #print myTexture

    for (i,item) in myMaterials:
        print "old item: "+item
        newitem=item.replace ( '.mp4' , '_00000.jpg' )
        newitem2=newitem.replace ( path2,'')
        #newitem3=newitem.replace ( '.mp4','' )
        newName=newitem2.replace ("\",'')
        print "New name is: " + newName
        print "------------------"
        #print newitem2
        print "--- replacing ---"
        newTexturePath = path1 + '\' + folderName + '\' + newName
        print "New texture path is: " + newTexturePath
        myTexture = newTexturePath
        print "code start"
        # Setup and add
        # Materials:[c4d.BITMAPSHADER_TIMING_TO]
        #if not mat: return True
        print oldTime
        newTime= (oldTime - 1)
        mat = c4d.BaseMaterial(c4d.Mmaterial)
        shader = c4d.BaseShader(c4d.Xbitmap)
        shader[c4d.BITMAPSHADER_FILENAME] = newTexturePath
        shader[c4d.BITMAPSHADER_TIMING_TO]= newTime
        mat[c4d.MATERIAL_COLOR_SHADER] = shader
        print newTime
        print "check"
        print shader
        print mat
        #return (mat, shader)

# print path
    #for fname in dirLister:
    #    print fname
    #    print myMaterials
    #print myTexture

# update the Cinema 4D UI

# tell that the processing was finished
    print " ------------ Finished processing.-----------------"                
    # gui.MessageDialog("Finished processing.")

if __name__=='__main__':

print "------------ Done."

Thanks for any help!
