I Removed the mirrored slate floor which should improve performance. I also added an actual environment but it can be toggled off from the E (environment button) in the scenes.
I added a second version of the scenes that uses thin version of Hanna which should work better if you are wanting to swap in looks that aren't as thicc as Lily.
Some animation adjustments to both versions which hopefully make things a bit more consistent.
Just load your appearance preset from the appearance preset tab and click the checkbox for locking the preset and go through the scenes with the look of your choice.
