This Horse model works in VRChat + Fullbody support has gestures for facial expressions and taking out the sword.
Please be aware that this model was for unity 2017 during roughness being there in the standard, IF possible I'd recommend Using a shader that uses Standard, This model comes with all respectful maps to make it look the best it possibly can.
Requires VRCSDK And Dynamic Bones
Later down the line there will be a substance file for editing the textures more efficiently.
