I'm pretty new to both Blender and Unity. I've been following tutorials on how to do facial animations, this one in particular: https://www.youtube.com/watch?v=b8-4IQr6PEg&t=9575s
This all seems to be working perfectly in Blender. However as I bring them into Unity, the armatures exist, with the correct amount of frames, however no animation appears to be playing in the preview. I've also tried bringing it into my game thinking there may have been a bug in my preview windows but no luck.
I've tested my character with a basic animation moving the head as a whole and this works in Unity. I think my problem is to do with assigning the bones to the shape keys (as per the above tutorial). Should this method work with Unity, and if so any suggestion on where I could be going wrong?
I appreciate any help, and any more information please ask! Thanks
