Hello there,
as most of you might know, Techne is a tool made for making Minecraft models. Right now, you can only choose the pre-made models, but if Techne-support is added, you can create your own models and use them in your animations! I hope you guyslike this idea.
If this is impossible, i'd like to see the enderdragon and the wither getting implemented in Mine-Imator. Right now, they are the only mobs not in the game and i'm planning to make a video featuring them.
