Well, the fur can not be transfered to a game engine, the rest should be good) If you mention me as creator of the base for your game model it will be completely fine to use it.
Unfortunatelly for me it is impossible to toggle stuff that is a part of the mesh. If you have some 3D skills yourself, you can just do it yourself. My models are quite simple. Just delete the sheath model things you need, connect them and unwrap just the area you added. Then is the shader stuff, its easy, dont forget about color attributes used in the model. Also tweak the fur in the area. Basically its around 2-4 hours of work)
