Thank you very much! The second way works great. I didnt get the first approach to work, but the second does well

Here is the script if someone needs it. It is probably messy I am not a programmer, but it does write the names of the selected materials into the texturname

import c4d
from c4d import gui
from c4d import storage
import  os
#Welcome to the world of Python


def changeTexture(shader):


    # shader ID
    texturePath = shader[c4d.BITMAPSHADER_FILENAME]
    # split aboslute path
    oldTexturename = os.path.split(texturePath)
    fileExtension = os.path.splitext(texturePath)
    # add prefix to
    newTexturename = matName + fileExtension[1]
    print (newTexturename)
    newTexturePath = os.path.join(oldTexturename[0], newTexturename)
    print (newTexturePath)

    # rename texture
    try :
        os.rename(texturePath, newTexturePath)
        print("Source path renamed to destination path successfully.")
    except OSError as error:
        print(error)

    # Assign the new value
    shader[c4d.BITMAPSHADER_FILENAME] = newTexturePath
    shader.Message(c4d.MSG_UPDATE)


# Main function
def main() :
    c4d.CallCommand(1029486) # Project Asset Inspector...
    c4d.CallCommand(1029816) # Select Assets of Active Elements
    c4d.CallCommand(1029820) # Globalize Filenames

    # Iterate over selected material
    material = doc.GetFirstMaterial()
    if not material:
        return

    while material:
        if material.GetBit(c4d.BIT_ACTIVE):
            shader = material.GetFirstShader()

            global matName
            matName = material.GetName()
            while shader:
            # Test if the current node is a bitmap shader.
                if shader.CheckType(c4d.Xbitmap) :
                    changeTexture(shader)
                shader (shader.GetDown())
                shader = shader.GetNext()

        material = material.GetNext()

    c4d.CallCommand(200000273) # Reload All Textures

# Execute main()
if __name__=='__main__':
    main()

Is it possible to make an iteration through a selection of Materials.
I'd like to rename the texture after the material. It works but only on all materials in the doc. how do i specify it on to a selection of materials?

            if shader.CheckType(c4d.Xbitmap) :
                changeTexture(shader)
            shader (shader.GetDown())

@zipit

hm yes this sounds too complicated overall, particularly point 3 there could so much happen on the os side.
A gui with more options like renaming the hole texturename or a replace option of certain words could be the way forward. Instead of undo it would be easy then to rename the texture with he old name etc.
for now im happy how this works and let this solved.

Much Thanks!
Cheers,
moko

@zipit Thank you! That was exactly i was looking for

here the new Version:
I throw out the undo function because i dont know if it can adress the os part. Is this possible to have an undo on os.rename?

import c4d
from c4d import gui
import os, sys

prefix="placeholder"

# Adds a prefix to the texturename
def changeTexture(shader):

    # shader ID
    texturePath = shader[c4d.BITMAPSHADER_FILENAME]

    # split aboslute path
    oldTexturename = os.path.split(texturePath)

    # add prefix to
    newTexturename = prefix + oldTexturename[1]
    print (newTexturename)

    newTexturePath = os.path.join(oldTexturename[0], newTexturename)
    print (newTexturePath)

    # rename texture

    try : 
        os.rename(texturePath, newTexturePath)
        print("Source path renamed to destination path successfully.") 

    except OSError as error: 
        print(error) 

    # Assign the new value
    shader[c4d.BITMAPSHADER_FILENAME] = newTexturePath
    shader.Message(c4d.MSG_UPDATE)


# Iterate a hierarchy
def recurse_hierarchy(shader) :
    while shader:
        # Test if the current node is a bitmap shader.
        if shader.CheckType(c4d.Xbitmap) :
            changeTexture(shader)
        recurse_hierarchy(shader.GetDown())
        shader = shader.GetNext()

# Main function
def main() :
    mats = doc.GetActiveMaterials()

    global prefix
    prefix = c4d.gui.RenameDialog("Prefix_")
    print (prefix)

    # Iterate over selected material
    for mat in mats:
        recurse_hierarchy(mat.GetFirstShader())

# Execute main()
if __name__=='__main__':
    main()

Now it works as intended. You can select the materials for which you want to change the prefix of the texturename. The actual name of the texture is not changed. You need to do this with a renaming-tool at the OS level.

thanks to everyone

Thank you very much, right now i am quite happy how it works. only thing is the dialog box opens for each shader because its in the "changeshader" function wich repeats.
I d' like to have one gui-call at the start in the main function, but if i do that theni cant transport the "prefix" argument to the changeTexture(shader) function.

about the time investement i agree, but for this script was more an out of desperation approach in how cinema4d lacks in organizing textures, then a new grind in passion. the script helps me with a hack, to organize them on OS side, for team projects like for instance unity.

Thank you for both inputs. Im not used to programming and copy and paste the lines. Thanks for the help!

Thanks it works like expected, now i would like to add a smal GUI but i get stuck, how do i bring the name from the GUI in as prefix.

import c4d
from c4d import gui

        self.GroupBegin(GROUP, c4d.BFH_SCALEFIT, 3,5, title = "AAdds a prefix to the texturename")
        self.GroupBorder(c4d.BORDER_GROUP_IN)
        self.GroupBorderSpace(20, 5, 20 , 5)
        self.AddStaticText(TEXT, c4d.BFH_SCALEFIT, name="Prefix")
        self.AddEditText(NAME, c4d.BFH_RIGHT, 200, 0, 0)

# Adds a prefix to the texturename
def changeTexture(shader) :

    # shader ID
    texturePath = shader[c4d.BITMAPSHADER_FILENAME]
    # split aboslute path
    oldTexturename = os.path.split(texturePath)
    # add prefix
    newTexturename = prefix + oldTexturename[1]

    doc = shader.GetDocument()
    doc.AddUndo(c4d.UNDOTYPE_CHANGE, shader)

    # Assign the new value
    shader[c4d.BITMAPSHADER_FILENAME] = os.path.join(oldTexturename[0], newTexturename)
    shader.Message(c4d.MSG_UPDATE)

        recurse_hierarchy(shader.GetDown())
        shader = shader.GetNext()

    doc.EndUndo()

thx for help
mok

Thanks alot it works! but the material iteration posts an error
def main() :
mats = doc.GetActiveMaterials()

doc.StartUndo()
# Iterate over selected material
for mat in mats:
    recurse_hierarchy(mat.GetFirstShader())
doc.Endndo()

it didnt find doc.Endndo() is there a way to iterate over the materials?

my second question:
now the script replaces A with B. Is it possible to "add" like a prefix?
I have alot of textures and would like to add a "Tex_" as a prefix, so its easier to sort/find them.
Like "TrainStation.jpg" to "Tex_TrainStation.jpg"

I found this but it need the name of a object or material:

Thanks for any suggestions and maybe someone need this aswell
cheers moko

Hi, i am looking for Texture renaming scripts and found this old topic
https://developers.maxon.net/forum/topic/10897/14346_textures-renamer-script
unforgently i have no knowledge in code.. my question, has someone the time to modify it, so it works with a normal cinema4d bitmapshader instead of vray?
thanks alot,
mk
