Hi All again. ok for complex sceens what i do is the folowing. Its a bit of work but nessasary. the cloth and hair rooms use a lot of computing power and memory to do there computations. so what i do is set up the sceen then if animated such as a horse and rider moveing through gates in a compatition. I would load the horse and minamul secondary props such as jumps and landscape. then set up and creat the animation for the sceen. now save your horse animation then remove him and the rest of the props. run you cloth or hair sims. reload the horse and the rest of your sceen. and render away :) all will be in proper place and motion. this should speed up the simulations for you. hope this helps laters Vel oh PS the above settings are starting points for you. tweek them to get the final result you want. dont go slamming the settings all over the place as a .0010 move up or down can make a very big diference. Laters and have Fun Vel
