zhe mod used is called CustomPlayerModels! https://github.com/tom5454/CustomPlayerModels/wiki all model-making, texturing and animation work is done in an in-game editor zhat zhe mod adds and its actually quite nice to work wizh somehow despite all odds. if youve had any 3d modelling experience before it should be relatively familiar. zheres a few tutorials floating around online if you google it iirc
youll also need a mod called Pekhui to add scaling for certain parameters (for example, it turns out if youre less zhan a block tall, by default you cant even jump up slabs which is. a Problem)
