Slimefun is a plugin that offers CustomModelData to support texturepacks, and if Slimefun is installed together with Magic, Magic will override Slimefun item textures

steps to reproduce (if necessary)

• download and install slimefun on your server
• download and install magic on your server
• start the server

you will start with an item called "slimefun guide" in your inventory, which is normally an enchanted book but you will notice that its texture has been replaced by Magic

• right click the book
  what you will see now is a visual clutter of Magic overriting slimefun modeldata
• you're done, you have successfully replaced the issue

/mexample add slimefun

sorry, what does this command do?

Turns on the slimefun-compatible resource pack

Otherwise, you have to merge the resource packs yourself. https://merge.elmakers.com

(for reference, I'm currently not using the non-official slimefun texturepact. It is just that Magic assigns its own textures to Slimefun's menus and items since they use custom model data)

that doesn't seem to be a command, might I be missing something?

Gah, sorry- I really need to add that alias since I always type it :(

/mconfig example add slimefun

The non-official slimefun RP is what is merged in the slimefun example

Ah, I see. Thank you for your assistance, much better now.

You're welcome!
I'm adding /mexample for the next release 😂
