View Full Version : help rigging with dynamic curves for interactive collisions

I remember seeing somewhere how a simple skirt was rigged in Maya using curves that were converted to a dynamic hair system, which in turn deformed the geometry. I have gotten that far, but I also remember the guy who showed it to me was able to drag a ball around the screen and the skirt collided with it realistically in real time, without having to hit play in the timeline. I can't figure out how to reproduce this.

My intentions are to use this method to rig a similar skirt for a female character, where it will collide with the character's legs in realtime, while the character is being animated.

Is this even possible, or should I just hide the skirt geometry until I finish animating the character, and then worry about the skirt moving later?

Does anyone know how to do this? Any help would be appreciated.

Hi..
To make the the curve collide with the sphere turn the sphere a colliding object to the curve.

I appreciate the response Shinyprem. I don't think I explained my problem quite right. I was able to get the curves to collide ( I am using collision sphere constraints). What I can't figure out is how to get them to solve (I think thats the right term) without actually hitting play in the time line. What I remember seeing was the sphere being dragged around on screen, with the time line staying on frame 1, and the curves interacting with the sphere when the ball was dragged across them. I said "realtime" but I guess what I really meant was independent of the time line. Right now, the curves I created only solve when I hit play. Otherwise they stay in the original position I created them at, even if I move the sphere back and forth across them.

I hope that makes more sense.

i believe there is a plugin from kickstand call stretch mesh that are able to achieve this. Also i think it would be better to approach this a a deformer approach then dynamic. I would also love to learn how to do this manually as well.

Did you ever find the solution for this? I am in a similar pickle with rigging a skirt.

I know that there's a mel command that will make a ball roll automatically (makeRoll; i think). but I don't know about the skirt interacting in real time though.

I still haven't found a solution that I really like. I figured out how to drive the skirt's animation with the dynamic curves, but not in "real time" yet (meaning having the dynamics solve without having to hit play in the timeline). I haven't found a "set it and forget it" solution either, which is what I am trying to figure out. For the time being I have gone on to other things that are more important (like actually animating my characters), but if I discover the solution I will post it here. Maybe I just don't remember what I saw and what I am searching for isn't possible yet.
