For the first time in a while I have decided to make proper changes to Kat. While she certainly wasn't lacking weight in the chest area, I felt that she lacked an appropriate "counterweight" on the opposite side. Thus, I have given her a much needed buff to the rear region as well as other changes. Here's some comparisons!
As you can see, not only is there a sizable increase in "mass", but her body in general is more defined and detailed thanks to careful use of some built in morphs.
In addition I have lowered the complexity of her hair for the sake of optimisation. There is a small (and in my opinion, negligable) reduction in fidelity in exchange for a
HUGE boost to FPS compared to her prior versions! If you want to see and be the judge yourself, here's another comparison.
