Hi guys
I am completely ignorant of scripts
I wondered if it was possible to write a script that would change the name of all the textures of a project, and relink them.
eg:
wood_diffuse.jpg becomes texture_001.jpg
wood_reflect.jpg becomes texture_002.jpg
carpet.jpg becomes texture_003.jpg
curtain_fabric.png becomes texture_004.png
.....
.....
all this with vray materials, where textures are placed in the VrayAdvBitmap shader

thanks a lot to everyone

Hi Zac Davide, first of all, welcome in the PluginCafe forum.

It's actually not necessary to bump a thread if a day has not passed.

Regarding your question, take in consideration we can only support c4d related stuff, and give you advice about it.
But as you may know or not, a vrayMaterial, is nothing more than a MaterialData and a VrayAdvBitmap, is a ShaderData.

All ShaderData are part of a MaterialData. So with the following script, you will iterate over all the shader within the selected material.
And change the texture path

import c4d
  
# Change the texture path to another one for a VrayAdvBitmap
def changeTexture(shader) :
    before = "wood_diffuse"
    after = "texture_001"
  
    oldPath = shader[c4d.VRAY_BITMAPCCGAMMA_BITMAP_FILENAME] # Read the current value, again I simply drag and drop the parameter in the consoel to knwo the ID
    newPath = oldPath.replace(before, after) # Replace before value by new value
  
    doc = shader.GetDocument()
    doc.AddUndo(c4d.UNDOTYPE_CHANGE, shader)
    shader[c4d.VRAY_BITMAPCCGAMMA_BITMAP_FILENAME] = newPath # Assign the new value
  
    shader.Message(c4d.MSG_UPDATE)
  
# Iterate a hierarchy and check if the passed is a VrayAdvBitmap shader
def recurse_hierarchy(shader) :
    while shader:
        # Check if it's a VrayAdvBitmap, I know the ID by drag and drop a VrayAdvancedShader into the console
        if shader.CheckType(1037364) :
            changeTexture(shader)
        recurse_hierarchy(shader.GetDown())
        shader = shader.GetNext()
  
# Main function
def main() :
    mats = doc.GetActiveMaterials()
  
    doc.StartUndo()
    # Iterate over selected material
    for mat in mats:
        recurse_hierarchy(mat.GetFirstShader())
    doc.Endndo()
  
# Execute main()
if __name__=='__main__':
    main()

If you have any question please let me know! :)
Cheers,
Maxime

I'll try it immediately, and sorry again for my "precocis bump" :)
