Textures not loading properly

[Dripan]

I just started out with mods, and I was trying to make some basic items. I got the items to load into the game but I cannot figure out what is wrong with the textures and why they are not loading. I checked the folder structure and the contents of the json files more than 5 times and I could not find anything misplaced or mistyped. I would greatly appreciate any help.

raw_plutonium.json

  "textures": {
    "layer0": "firstmod:item/raw_plutonium"
  }
}

plutonium.json

{
  "parent": "minecraft:item/generated",
  "textures": {
    "layer0": "firstmod:item/plutonium"
  }
}

I would like to include a screenshot of the resource folder structure in case I might have somehow misplaced something but I couldn't find how to paste the image. Also, I have read other threads on this but it did not help, couldn't find anything wrong with my code.

Your textures path should be for example resources/assets/firstmod/textures/item/plutonium.png

and your mod id must be firstmod

Expand  

the mod id is firstmod and the folder structure is the same as the one you have mentioned

Are you sure "layer0" points to a valid item texture? If a json item model doesn't use an existing image file for it's texture(s), then it will have the purple and black checkerboard texture.
