How to Make a Minecraft Texture Change Based on the Name of an Item [Hypixel Skyblock]

In this video I will be showing you guys how to change the texture of an item in Minecraft using a custom resource pack. This can be used in gamemodes such as Hypixel Skyblock where different items share the same base model. Use this to differentiate between different items. As far as I'm aware this only works for items, not blocks or entities. I'm sure there are ways to do this for different types of visuals, however that is not what I instruct upon in this video.
I made another tutorial on how to do this with animated textures HERE: https://youtu.be/U61phiw3UeU
FAQ:

What versions does this work in?
- As far as I know this works in all versions between 1.8 and 1.16 that optifine is available for. some people have had trouble getting it to work in 1.16 versions.

Can I use your pack in my project?
- I am perfectly fine with you using the textures I created, however, my pack includes modified and completely stolen textures from the vanilla+ pack (linked below) and other pack makers who I have forgotten the name of. As to avoid too much confusion I will say no, you cannot use this in a personal project (such as a server, website, or other external content).

My texture isn't working. can you help?
- Post a SPECIFIC comment in the comments section detailing what your issue is. Without details, I can't help. Additionally, you can join my discord (linked below) and get help in the #texture-help-and-showoff channel.

Can you make a tutorial for X item (bows, etc)?
- Honestly, I want to. The problem is I don't know how. If I ever take the time to learn how I will make the video and update this question.

How do I animate the textures?
- I made a separate video on that here: https://youtu.be/U61phiw3UeU

How do I do armor?
- I made a video on that as well: https://youtu.be/6QLk5MbfGls

How do I do bows?
- my fourth video was on that: https://youtu.be/kaXmSxqX1N4

My textures show up as a null item (purple and black squares).
- Double check that you made the .properties file EXACTLY as I showed it. Also ensure that the latest version of optifine is installed.

My bow texture isn't pulling back.
- There is a bug with Optifine version L5 for 1.8.9. To fix this you will need to upgrade versions.
