View Full Version : Clothide Problem!

 Suwat4D03-13-2006, 12:23 PMHi every one!... :scream: I need help (emergency!); I am having a problem working with Clothide, I 'm trying in many ways, but still having this problem which is as following; http://img75.imageshack.us/img75/7111/clothideproblemseq807jr.jpg http://img75.imageshack.us/img75/7374/cuclothideproblem5ez.jpg http://img88.imageshack.us/img88/6631/chsetting6kw.jpg and a QuickTime movie file > http://www.thai4d.net/problem/clothide_problem.mov If you see my work, you will see the scene that the cloth suppose flows with the actor’s body, but it slowly move apart for the actor. ( and some time it looks like moving too slow) I am wondering if anyone can help me with this problem thank you :)

hi

the first problem is caused by the hand which is intersecting your cloth. you can either define only the legs as collision objects or finetune the animation and don't let the hand intersect the cloth.

the second problem looks like it's way too extreme leg movement for such a piece of cloth. you could add a big seam on the side.. currently it looks like he's doing martial arts with a towel around his legs.. not a good idea imho ;)

You might want to add some 'Gobal Drag' - this might help with the balooning out - a setting of about 4 - 5 might do it.

Alsomight be worth lowering the Flexion value down to 1 to make the cloth a little more flexible.

Stiffness is a bit low. Are those actual frame numbers on the pictures? If yes the movement is way to fast for reliable cloth simulation. It's like moving a curtain with supersonic speed.
To avoid the intersection problems you can exclude the hand polygons from collision (see options in collider tag).

Much depends on the speed of the movement. You might like to try increase the sub sampling a good deal.
Also keep in mind that the action of your character would be hindered by the cloth in real life too. Currently it looks like it is trying to stretch well beyond it's original size. If this is intended then you should allow for correct stretching by increasing the rubber value. Be aware that it will look like rubber though.
I have adjusted my clothrules (http://www.bonkers.de/mocca/clothrules.html) to this.

:) Thanks for your suggestion I have tried to follow your suggestion, it's getting better. I increased the sub sampling more, it is workig but have to spent time more in calculation.

keep in mind how you've actually modeled his wardrobe too. I'll tell you right now that cloth sim wouldn't be physically possible in the real world, such an outfit would be a wrap and therfore have an area slit open, greatly reducing the amount of stretching involved.

What about elastic skirts? Seems impossible with Clothilde.
