I think this post is long overdue, but it's important that I say this.
This project is dead. After my initial enthusiasm for this mod, my ability to continue working on this mod waned, and as you all know, it has slowly frozen in development. Furthermore, with the pace of Minecraft development, huge changes have been made to the structure of Minecraft, to the point that the mod has been over 60% re-written, and there are still many changes that need to be made to make a feature-parity update that works with Minecraft 1.11.
This all said, I think it's time that I announce that I will officially no longer be working on this mod. I know, this should have been said a long time ago, and I apologise for my awful communication.
I will build and upload the latest version in a couple of hours, and remove the ads from the existing links. If anyone wants, all of the source code is available in a GitHub repository (linked in the main download post), which can easily be downloaded and continued. I'll also upload a zip containing every model I have that was never implemented, so that if anyone continues this, they have a slightly easier time getting started.
Once more, I'm so sorry that I've left this so long, but I hope that with this, people can either take up further work on this, or accept it's stagnation.
Thanks for all of the support for the last few years,
