(ponytail) gravity on softbody with goal

[sturmkim]

if your goal is (or near) 1. field is not effect to your particle.

low down your goal,(around 0.5 for highest). you have to do a lot of tweaking to get good simulation.

if you are using unlimited ver., i will use hair dynamic curve as ik spline tool curve.
you can find howto in this forum.

thanks for the reply sturmkim but a large part of the ponytail's goal is set below 0.5. I even tried turning up the gravity field's magnitude but still nothing.

i agree with sturmkin, maya hair is the way to go for making hair. funny huh.. its designed for hair, so it works great on pony tails. all the features you want can be accomplished much more easily and with less fine turning than with soft bodies. for most thing i used to use soft body for, maya hair has made it obsolete with its instant reliable spline dynamics. all those steps you outlined can be accomplished far more quickly, create a spline, convert to dynamic curve from the hair menu, go in the options and set it to only have the base pinned. viola, you are bascially done. you can fine tune it, but its actually fine tuning something that basically works correctly, not trying desparately to make things not blow apart as with softbodies.

just wanted to mention an alternate workflow. i bet you will get it working faster if you start over with maya hair, than from however much progress you made on soft bodies. if i lose the bet, i'll apologize to the people who coded soft body dynamics :)


as to debugging your exact situation, have you tried attatching the gravity field in your scene to another soft body and see if it works at all? you have to isolate every factor in your scene, you have many things going on at once. once you get the gravity working at all, add in all the other dynamics stuff, one by one, and test it every time to make sure all the old stuff didnt' break. throwing on a ton of stuff at once and trying to tune it all, usually causes big headaches, especially if you are still learning what each feature does by itself :)
