I just wanted to create my own project (Minecraft server) on datapacks. But I remembered that for some datapacks we need a resourcepack! Since there will be many datapacks, there will be many resource packs for them. And installing them separately is not so cool. In general, I heard somewhere about such a site where you can combine several resource packs into one. But forgot about him. Can you please say if there is such a site at all, if there is, then discard it to me please.
It can be a bit of work, but I believe you can do it yourself by just combining the files and deleting the textures that you don't want? I don't know how viable that is for your situation, but it may be worth a shot.
It's really easy to to it in files, I done it and I am happy about it best part of that is, I can do everything Some textures edit just a bit in editor, some texture "stole" from another recource pack.. It's private, so it is not bad to "stole" some textures
