I've struck into a, probably easy to fix issue.. but i can't find out what the hell to do.
What i've done to remove the need to have two seperate objects with seperate textures, i animated only the door vertexes to follow along a Empty Object as simply just animating the vertexes diden't seem possible.
The animation and all turned out great inside of blender, but importing this into Unity seems to have issues, could it be since the animation is actually based around another object?
(Yes, High resolution textures untill i get it into the game running, Planning to scale them down later. Also i did export into .fbx when importing to unity, uploading the .blend just for ease.)
