Yep, that looks about all of them!
I don't exactly know yet how to add item models for these, mostly because i haven't been able to properly look at the new rendering system yet.
There are block models, and they work just fine.. Now i need to get the TESRS rendered as an item..

I am in the process of learning how to mod for minecraft, I have a very basic understanding of Java, but I have some coding experience in other languages and I found an interesting set of tutorials I am working through that deal with this exact issue. Hope it helps. I would be interested in helping out if your looking. Figuring out the .json seems fairly simple and the item and block registering code is not that bad from what I can see, though I have never coded for mincraft before so unlearning the old to learn the new isnt an issue for me.
