View Full Version : Shirt explode help

06-09-2010, 11:23 AM
Hey guys, so Im trying to make a shirt explode, basically like the transformation scene at the beggining of this clip.


Thats what Im trying to achieve. Heres where Im at.


Basically, I have the shirt, I made some tearable constraints on it. Then I animate the glue strength, while animating the pressure of the cloth to make the shirt tear. Thats what I figure was the best way to approach it, its not quite working though. Not sure where Im going wrong. Its not exploding though. It like sort of puffs out and rips a bit. Heres the scene file.


Any help with this is appreciated. If theres a better way to do it, Im completely open. Thanks in advance.

do a search for one of my posts in past month or so on how to trigger tearing... the scene in there should help you out...

Hi Howard, thanks for the reply! I took a look at the post you mentioned. I dont think I quite get it. Im pretty new with nDynamics. I dont get attract mesh or component constraint. Is that what is supposed to help me get the explode effect? I dont think I quite get your example and how it relates to mine. Sorry, Im still new to this, so I dont see the relation. What am I supposed to be getting out of the example you provided.

Dont use pressure to blow the shirt apart. Use a newton field instead.

ok well maybe my technique will be overkill for you. it just gives you more control of what parts will break off and when, using a ramp (or texture) to control it.

the attract mesh is simply used to hold the shirt in place (or to the animated input mesh), otherwise the field would be ON always...

then the ramped texture is used to release the cloth...

so for your scene, you simply need more power in the fields you use, instead of pressure...
