Please make an example resourcepack, the folder structure is very unclear in the Wiki.

The folder structure is just the same as vanilla.

The problem is more that I have no idea where I have to make the files and stuff, a example resource pack would really help to understand the folder and file structure.

Fusion does not change where you'd have to put the files. It's just the same as a regular resource pack.
There's plenty of examples for resource packs out there.

Still I can probably create a repository for a resource pack which contains everything mentioned on the wiki.

The problem is more that I have no idea where I have to make the files and stuff, a example resource pack would really help to understand the folder and file structure. It would make the possibilities more clear too.

When is the resource pack released? I am really trying to understand, but some arguments are just out of my understanding. I am just getting this texture. https://media.essential.gg/4c63f970-4364-4d33-36aa-ee85a50c7400
A resourcepack with every possibility would be really helpful!

Did you add the .mcmeta file for your texture?

Yes I added a mcmeta file:
{
"fusion": {
"type": "connecting",
"layout": "full",
"render_type": "cutout"
}
}

Make sure the location for that file is correct. If you a file planks.png, that file should be planks.png.mcmeta.

Okay. I also noticed, that I have the .json file only in the models, not in the models/block. I'll retry.

It worked! Thank you for your help! I'm just having some texturing issues now, but I can fix them on my own.

Okay I'm having another issue. I am trying to make block overlays, but it doesn't work. I have checked the folder structure and have copied the data from the wiki. What am I doing wrong? (Picture of the gravel: https://media.essential.gg/565c837a-6819-4830-5998-118b2d0bc400)

I can't tell what is wrong from just an ingame screenshot. Please share the relevant files.

Yeah sure! Here:

Fusion.zip (That's the resourcepack)

You need to add the example:sand_overlay texture to the block atlas. Any texture in the block folder will automatically be added to the block atlas. For textures outside the block folder, you'll have to add it to the block atlas yourself if you want to use the texture on a block. This is done through the atlas source files.
https://minecraft.wiki/w/Resource_pack#Atlases

I honestly don't know how to do that. The wiki says the path is relative to the textures folder, so how do I add textures outside of "minecraft/textures"?

Could you give me the file required to add the texture so I can understand it?

Simplest option is to just move the example:sand_overlay texture into the block folder.

The other option is to add it to the block atlas through the atlas source file. This is done by creating a assets/minecraft/atlases/blocks.json file with the following content:

{
   "sources": [
      {
         "type": "single",
         "resource": "example:sand_overlay"
      }
   ]
}

Everything you have asked so far is just vanilla resource pack stuff and unrelated to Fusion. For examples, you can probably look into other resource packs, the Minecraft wiki, or texture pack tutorials.
There's also this resource pack on CurseForge which uses Fusion, which might also help as an example: https://www.curseforge.com/minecraft/texture-packs/mt-ct-d

I've never changed any models until now, but thank u for helping me. (That's the reason why I wanted an example resource pack. I learn by exploring)
