GUIDE [Tool] McModels / BuildByBit models credit remover – Remove account IDs (multi-site support)

Other sites won't delete your account info. ​

What does this do?​

When you download models or resource packs from McModels, many files (.json, .bbmodel, .yml, .png, .ogg) still contain a model_identifierfield that ties the content to the uploader’s account. This script automatically finds and removes every trace of those IDs from all supported file types, then repacks everything into a clean .zip file with a unified date (01/04/2026). You can drop a folder, a .zip, or a .rar onto it – it handles the rest.
Requirements

• Python 3.7+ - python.org or PyPy - https://pypy.org/
• Optional libraries (recommended for full PNG/OGG metadata cleaning):
  
  
  Code:

  pip install Pillow mutagen rarfile

  If you skip these, the script still cleans JSON, BBModel and text files perfectly.

How to use the script

1. Save the script as remove_credits.py anywhere you like.
2. Drag & drop (easiest): Run the script (double‑click or python remove_credits.py). When asked, drag your folder, .zip or .rar file into the console window and press Enter.
3. The script scans every file, shows found IDs, cleans them, and creates a new file named <original>_.7z in the same location.
4. You can keep processing more items in the same session.

What gets cleaned?

• JSON / .bbmodel / .mcmeta – removes the model_identifier key and any line containing the ID.
• Text files (.txt, .yml, .yaml) – deletes comment lines with the ID, model_identifier entries, and any leftover ID strings.
• PNG images – scrubs the ID from text metadata (author, description). (Needs Pillow)
• OGG audio – scrubs the ID from Vorbis comments (artist, title). (Needs mutagen)

No original files are modified – you always get a fresh _cleaned.7z The original folder or archive stays untouched. The output .7z always has all file dates set to 01/04/2026 so the pack doesn’t leak original timestamps.

Check your cleaned pack with WinDirStat​

If you want to be absolutely sure no personal information remains in your pack, you can visually inspect its contents with WinDirStat (Windows Directory Statistics). It shows every file inside a folder as coloured rectangles, making it easy to spot leftover or other files that shouldn't be there.

1. Download WinDirStat
2. Extract your `<original>_.7z` to a new folder.
3. Launch WinDirStat and select that folder (or directly open the `.zip`).
4. Look for suspicious file names, unusually large comment blocks, or any file you don’t expect – if the script worked, you’ll only see the intended resources, nothing more.

This step is entirely optional, but it gives extra peace of mind that your pack is completely clean.
