2015 - Animator Friendly Cloth Simulation in Motion Builder for Kingdome Come: Deliverance 

+Andreas Nick basic idea was precomputed physics that can be animated (on huge amount of game animations) since realtime physics is still cpu heavy if you have multiple characters on screen even today. So for this skirt test, there's 8 4-bone chains that are easily animatable (even from scratch) and you can solve problems with sitting and other hard poses and yet it will be ok for most of the situation. Currently it's R&D which get's complicated by the fact that we have clothing system in WH in Kingdom Come, which means layers of clothing in unknown order and type and with huge amount of combinations ;) Trick is that I'm not solving cloth and then retargetting it to bones but solving the simple cloth equations directly those bones with few simple tricks to prevent penetration etc.

+Jan Zamecnik Seems to work well in your test... I'll try to set up something similar in Mobu. Thanks for the inspiration.

+Andreas Nick You will soon run into obvious physics problems. There's more tricks to it than it seems. Collision treated differently based on movement, limits based on various dynamic parameters etc... Point it that "this is almost not physics anymore" ;)

+Jan Zamecnik Hey if it was simple I would have already done it... ;) But thanks for pointing out some traps.

+Рпагор Предович Thanks. It's an old work-in-progress

well, it's 7 year old now. It was udes in women's skirt for KCD DLC. I would say, that these days, You'll have better luck with realtime cloth simulation. What this was custom verlet simulaiton specially build for bones chains that prevent them to slip from knees and heels. It was build so it "stick" to the collision, so I needed only few bones and yet the leg did not penetrate. Animators then go thoguht the animations and correct glitches. It was all writeln in Python as MOtion Builder script
