А вообще!Встречаются курьёзы в этой жизни что без нормальных нормалей и нет собсно жизни!Прошу прощение за каламбур.Это любовь к майке и снова блэндер.Курьёз вот в чём.Если к этим привязать кэш то тут нашлось решение http://tea3d.blogspot.gr/ а,то что на creative crash пишут там какие то ошибки типа в винде не грузит,так у меня всё работает берём этот код и вставляем в script editote где Python и жмяк на exekute(такой треугольничег похож на значёк плэй в скрипт эдиторе)

Author: Alex Manita
Description: This tool designed primarily for export meshes and particles out of maya,
so they could be imported later into Houdini and other packages
Usage:
import fx_mdd_obj_exporter
fx_mdd_obj_exporter.runUI()
License: You can use it everywhere and modify but you cant sell it.
Use and Modify it at your own risk with absolutelly no warranties.
