might seem like a nitpick but the texture of the model haydee has right now is not the same that she had while the project was in ren'py. I don't know if this is a limitation of unity, but could you look into it?
It takes time to figure out Unity shaders. Most textures in Blender are literally made with nodes, which are either absent or work differently in Unity. I'll take care of this after releasing Build_4.
