View Full Version : Animating a streamer

Hello,

I am currently trying to animate a long streamer being blowen around in the wind. The streamer is a nurbs plane object and has many isoparms for deformation.

I have made it a softbody object and attached it to a turbulence field. It has a goal weight that I will paint in later to make one end stick in place.

My problem is that as the streamer is being blowen around the points are pulling apart everywhere. I think I'm supposed to use a spring to constrain their positions to each other but it isn't working. :(

Can anyone tell me what I am doing wrong?

Thanks.

You can adjust the stiffnes and the damping of the springs.
Hope that will help you out.

Thanks galactor, I am getting much better results after playing more with those. :) There is still a fair bit of distortion though, but I think I can cover it up for now.

Rather than making the whole plane a soft body, make a joint chain,
then make a spline ik with that chain,
and then make the spline ik curve soft (make original soft, goal weight 1;) )
Then, you can assign different weights in the component editor, with particle0 at 1, and reduce the value up to particle n at .1 (or whatever you want).
When you attach your mesh to the joints, it'll be schweet.

Thanks for your reply BigSky, sounds like a good idea. :)
