Blender - Converting textures to .webp then reassigning .png, .jpg, etc. textures as .webp

import bpy
import os

count = 0

for image in bpy.data.images:
    if image.filepath:
        old_path = bpy.path.abspath(image.filepath)
        base, ext = os.path.splitext(old_path)

        # Skip if there's no extension (like generated images)
        if ext:
            new_path = base + ".webp"

            # Optional: only replace if the .webp file exists
            if os.path.exists(new_path):
                image.filepath = bpy.path.relpath(new_path)
                count += 1
            else:
                print(f"⚠️ Skipped (no webp found): {old_path}")

print(f"✅ Replaced {count} image(s) with .webp versions.")
