hey, this is the 1.12 lucarion model. You are free to modify it and repost it. (if you repost it with 0 changes, say my pseudo but if you change something, than it is yours)
It have custom walking and running animation. if you want to know how i made the animation, you can ask me on discord (▄█▀zerustu▀█▄#0075 or on the CPM discord https://discord.gg/uVT39n5) the short explanation is that i have a tool that convert blockbench animation to a sum of sin and cossin function. the walking timer is use to know where whe are in the animation, when walking it gos up and when you stop walking, a strange function get it to the nearest round value (or half value) to get a smooth transition.
the tool used to make the animation can be found here : https://github.com/val9k/CPM_1.12_animation_tool.
