параллельно с с# 
и 3dmax 
уже 2 месяца. есть продвижения, но в некоторых моментах полный затык. дело вот в чём, так как с кубиками играться не особо интересно выдрал модельки и анимацию из популярной стрелялки killingfloor. анимаций ~750 штук юнька ворочала в метаданных долго поэтому пришлось засунуть всё в бандл, отрезал анимашки при помощи скрипта из антареса (немного допилил для батча). всё красиво грузится за пару секунд модельки двигаются как надо. теперь захотелось модельки сделать сборными рукиногиголовабоди и дополнительный кастом да чтобы ещё и отстреливать можно было. и вот здесь то выходит несостыковка. прочитал http://unity3d.ru/distribution/viewtopic.php?f=87&t=2051&start=15#p21425 что можно сделать отдельно скелет с шаблоном и подключать к нему отдельные меши беря информацию по костям из шаблона. нарезал модельку подключаю, а её корёжит так что маманегорюй. пересчёт весов не помогает.Синтаксис:
