After following the tutorial by bedrockminer, I have come to a part that my item just wont render at all.

 

I have followed all the steps precariously, but I keep getting errors depending on the changes I try.

I'm wrestling with github and eclipse to make my code visible, so tips on that would be welcome too

 

The error I have right now, with the same code as the tutorial, is as follows:

[11:27:51] [Client thread/ERROR] [FML]: Exception loading model for variant messycore:copper_ingot#inventory for item "messycore:copper_ingot", normal location exception:

Well for one the tutorial you were using was for 1.8, and you are using 1.10.2. If you would post your JSON model here.

This is all I have in the copper_ingot.json located in assets.messycore.models.item

 

{
"parent": "builtin/generated",
"textures": 
{
	"layer0":"messycore:items/copper_ingot"
    }
    
    "display": {
        "thirdperson_righthand": {
            "rotation": [ -90, 0, 0 ],
            "translation": [ 0, 1, -3 ],
            "scale": [ 0.55, 0.55, 0.55 ]
        },
        "firstperson_righthand": {
            "rotation": [ 0, -135, 25 ],
            "translation": [ 0, 4, 2 ],
            "scale": [ 1.7, 1.7, 1.7 ]
        }
    }
}

Why not try using this

{
    "parent": "item/generated",
    "textures": {
        "layer0": "messycore:items/copper_ingot"
    }
}

That did the trick

 

Any recommendations on 1.10.2 tutorials?

I don't think there are any right now, but if you are basing items/blocks off of vanilla ones you can look at there JSONS from either the forge source reference library or go to your .minecraft directory and look in the jar file under assets/minecraft/models.
