What happens when you remove a content pack?

SolaceMC

I have a bunch of content packs on our server, and I wanted to run a test because I'm struggling to understand the custom model data allocation. I put a custom texture on a sword, then deleted the pack from the resource pack folder, then after the restart ran /iazip.

Upon doing this, the sword texture changed to a different texture, from another pack. It wasn't just no texture, or a buggy texture, it was a DIFFERENT but working texture. Can you please explain to me why this is happening?

Following this, are we safe to delete unused packs? Say a furniture set that was never released, so nobody has any, is there any risk in removing this from the contents folder?

Thanks!

Hey Solace, if an item has a CustomModelData of 5 but you remove the texture associated with 5, that item will now use the texture associated with Custom model 6. If you'd like to suggest some behaviour changes to this, you could make a feature request on the GitHub

It is perfectly safe to delete unused packs, make sure you're running the /iacleancache command after removing stuff, to make sure everything updates correctly.

Verum Ohhh that makes a lot more sense, thank you!

Second question on the cleancache, so the recommended routine is:
- Delete unused packs
- reload server
- /iazip
- /iacleancache
Does that seem correct?

And that won't change any of the id's for items kept in, it will just clean unused numbers I assume?

Hey Solace, apologies for late reply. You'll want to run /iazip again after you've run /iacleancache
