What happens when you delete some textures, then add in new ones?

SolaceMC

I can see that various textures and packs are assigned a custom model data value, from 10000 onwards. So if I choose to delete some textures from the resource pack, that are not used or placed anywhere in the world, then reload the resource pack, is there any risks there?

I'm assuming it just removes the custom model data mappings right, so then if I add new textures/packs, they take that spare number space now created? Or should I instead be manually choosing a custom model data number for every texture, to avoid this sort of stuff?

Thanks!

Hey SolaceMC, IA has an in-built command for just this scenario to remove any unused assets. Simply run "/iacleancache items/blocks"

Verum Is this removing textures that have not been placed anywhere in the world? I mean more what happens when I delete the actual textures from the pack, and the downside of cleaning the cache etc?

I'm worried about any overwriting or anything of textures, just trying to understand how it all works.

If these textures were placed in the world, they'd change to the next available model data or the new texture that is the same model data number previously. If there is no other model available, it'd revert to the base texture used for the model.

If you used a custom ore or similar generated in the world, you'd want to plan ahead to replace this to a new block before removing. For this you'd use the world populators to set it up. Always worth planning things out carefully when it comes to anything outside of your initial spawn.

Verum Ah okay yeah thanks. So our main concern right now is about textures that are in our resource pack, mainly for weapons and furniture, but never released to the players, so there isn't any in the world or anything. Are these just fine to delete whenever, and is best practice to then run an /iacleancache after?

Also, should I be specifying the custom model data values when loading in a new pack, to guarentee no issues there?

Verum I have a problem related to the above.

I have a bunch of content packs on our server, and I wanted to run a test because it's not making sense. 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? It's concerning me and I don't get why it does that

Also another thing we're yet to solve - is it possible to remove just some textures, from a content pack? So not delete the whole pack, just some of the unused textures inside it?
