Hi Hair and cloth are both very mem and cpu intencive. so the best thing to do with a slower or comp with limited mem is the folowing. 1: load figure set animation keyfraims up. 2: load hair. and only hair. set and run the sim. save the hair as a pz3 with sim. if useing dynamic cloth remove hair. run sim. reload hair run sim. things to check if you cant run the hair sim with nothing else but the character. check the number of Vers per hair. and the number of hairs. if these are set high like 100 verts per hair and 1500 hairs well 100 X 1500 is a lot of pollys to deal with and these seting need to be checked for each hair group. Depending on the size of the group and how curly the hair, denotes how many verts needed and how many hairs. bangs for instance 1 to 200 hairs is useualy pleanty. Vert 20 to 25 will give good results. you get the idea :) have Fun Laters Vel
