>>2859410They should be perky by default though. Ironically, when I load the sample kappa in MMM, her tits go upward with physics rather than sagging in their default state. I feel like I explained it before, but I can't find it in the archives, so, first things first, there is an English translation of the PMXE ReadMe:

Surely, you remember Newton's second law from school? It works just like that. Less mass, less momentum = milder movement. Lower damping means longer duration of effects from model movement or collision. Repelling forces the body away from any colliding ones, while friction makes it stick. Body sizes below 0.01 radius spheres appear to stop working.
Joints are responsible for scaling the other multiplicator, the acceleration (the bounce figures), as well as for limiting the extent to which rigids in a physical pair can move relative to the joint and each other. Oh, here's a pic from before, a.k.a. that explanation:
