@VirtualWorldDynamics; "I want just to send my next version in May. " - thought that might be the case - no problem; I'm not in a hurry to do lots of work.... "Remember that the free edges of the collision shirt must be removed from the simulation." The shirt I am using hasn't been through a simulation as it fits my character perfectly. Do I still need to remove the free edges and if so, how - as it hasn't been through a simulation? Thanks
