Just trying to write a simple script to find all the duplicate textures that usually end in " .001 etc" and set their user count to zero so that on saving the file is nice and clean with only one of each texture left.
The code below seems to work great but the only problem is that all the materials/nodes that referenced the old duplicate names now are unlinked and have to me manually updated… I found how to access the user count but not to find the actual datablock they are linked to.
Anyone know how to find the users of the image textures so they can then be relinked to the correct names in the script?
import bpy
print ("start")
ilist=[]
ilist_dup=[]
for i in bpy.data.images:
iname=i.name
iusr=i.users
print (iname)
ilist.append(iname)
if iname[-4] == "." and iname[0:-4] in ilist:
ilist_dup.append(iname)
i.user_clear()
#print (iname)
print (ilist_dup)
OK that’s what I found and managed to scrap together a small script by using other peoples similar code and the blender python api which, frankly - is not very helpful or clear in explaining exactly what data you are retrieving and how to modify it with the various methods etc listed …
Feel free to use the script below. It simply takes all the duplicate images - eg… ending in .001 usually- in a blend file and sets the user count to 0 for them so that on a save and reload they are gone YAYY!.
It also searches the materials in the file and every time it finds an ImageTexture node in a material it relinks the correct image back so that after deleting the duplicates you aren’t left with broken materials!
Todo: for someone with more blender2.6+ python experience you could also add a new loop to the code that would loop through the materials that don’t use nodes such as the blender internal render mats and find images/environment textures and fix the broken names as well. Right now it only does this for cycles mats that use nodes…

#print (iname)

if node.image.name[-4] == "." and node.image.name[0:-4] in ilist:#and node.image.name in ilist_dup:
#print(node.image.name[-1])
new_i=bpy.data.images[image.name[0:-4]]#node.image.name[0:-4]
print("node" , node.bl_idname , "replacing",node.image.name,"with",node.image.name[0:-4])
node.image=new_i
