[Blender] Importing Blender shape key drivers?

I’ve watched a lot of Blender facial animation tutorials and most of them use the Drivers to control the shape keys.
The facial rig is connected to the body rig, and in the animation editor in Unreal I can see the facial rig moving but it just doesn’t affect the shape keys. I was just wondering if there was a way of getting the shape key drivers to work, because I don’t want to have to have to control the shape keys separately to the body in Unreal?

Any other options would be appreciated too. Thanks in advance :slight_smile:

I don’t believe you can you would just normally make the animation outside of ue4 them just import it when done
