Thanks a lot @The_M0ss_Man !
The trick is to have the chance to work with an amazing actress. 
In good light conditions, Metahuman animator is astonishing !
As for the narrative, I’ve been writing the script for a year. And I’m adapting the story to the capabilities of Metahuman. It’s exactly the same process I use for theater … I work with actors on stage and adapt the story to what they deliver.
As director of photography, I take a lot of time to light the scene to enhance the emotion of the metahuman actor’s face. Storytelling is about mixing all these parameters : acting performance, framing, light and screenplay. And Unreal 5 is just another way of bringing this cocktail to the public. 
I’ll be sharing a few exclusive clips along the way.
