just a reminder: selling minecraft java content is against the minecraft license, the license prohibits the selling of data packs, mods and plugins

USING mods
If you've bought Minecraft: Java Edition, you may play around with it and modify it by adding modifications, tools, or plugins, which we will refer to collectively as "Mods." By "Mods," we mean something original that you or someone else created that doesn't contain a substantial part of our copyrightable code or content. When you combine your Mod with Minecraft: Java Edition, we will call that combination a "Modded Version" of the game. We have the final say on what constitutes a Mod and what doesn't. You may not distribute any Modded Versions of our game or software, and we’d appreciate it if you didn’t use Mods for griefing. Basically, Mods are okay to distribute; hacked versions or Modded Versions of the game client or server software are not okay to distribute.

Any Mods you create for Minecraft: Java Edition from scratch belong to you (including pre-run Mods and in-memory Mods) and you can do whatever you want with them, as long as you don't sell them for money / try to make money from them and so long as you don’t distribute Modded Versions of the game. Remember that a Mod means something that is your original work and that does not contain a substantial part of our code or content. You only own what you created; you do not own our code or content.

to summarize:
Datapacks, Mods, and Plugins: You are allowed to create mods, datapacks, and plugins, but you cannot sell them directly. Instead, you can monetize them through methods like donations, ad revenue, or charging for access to a server that uses them. Direct selling of these items is generally considered a violation of the EULA.

is it possible if you make it a texture pack?

any eta for 1.20.5+? fixed the datapack by myself, however the resource pack seems to be incompatible for 1.20.5, some shader issues
