To add custom costumes for characters:
- Ensure that your new model does not override the original (change the model name/directory)
- Ensure that your new model is using $includemodel in the QC and pointing to the original model
- Your model shouldnt have any animations in it, only a "ref" or "reference" from the original. If you do include any animations, they will override whatever I have in the original for your model only (which if youre wanting to use custom animations, make sure they're setup correctly)
- Create a lua file in your addon folder (Example: lua/autorun/mycostumes.lua)
- Add this to the file:

The first string parameter is the NPC's class. The second string parameter is your model/costume.

Assuming all is done correctly, you can now view your costume in the character menu and spawn in with it equipped!

Here is an example additional costume all setup and ready to go:
