I am trying to get into modding and followed this tutorial:

https://www.youtube.com/watch?v=rQLhheYcnrY
so i've pretty much copied everything one for one except changing some names, but my texture won't load.

The java console displays me this error:

I've tried changing some paths and changing the mod id but nothing worked and i only see black and purple squares ingame.

 

My Json looks like this:

{  
   "parent":"item/generated",
   "textures":{  
      "layer0":"ym:items/Janson"
   }

and my ModItems file like this:

package com.Gallaglan.YoloMod.init;

import java.util.ArrayList;
import java.util.List;

import com.Gallaglan.YoloMod.items.ItemBase;

import net.minecraft.item.Item;

public class ModItems 
{
    public static final List<Item> ITEMS = new ArrayList<Item>();
    
    public static final Item JANSON = new ItemBase("Janson");

}

So what can i do to fix my mod?

 

Read your error:

Caused by: java.io.FileNotFoundException: ym:models/item/janson.json

ah right found the problem.
I had to rename my json file to only lower case letters ^^

thanks
