I'm not sure if this can be done, but I think I've seen videos of someone playing with the cloth sim to make curtains I think, they grabbed the cloth and slid it left and right across something a few times to make it ripple. I'm just wondering if I can do that and how. I want to see if I can do that but do other stuff like that to have more control over the physics.
- create a plane, subdivide it with 40
- add a vertex group like this:
give the plane a cloth modifier, shape -> pin group: your vertex group from 2
add 2 shape keys
on frame 1 insert keyframe for value 0
on frame 100 insert keyframe for value 1
Shade smooth on plane
i was lazy, all cloth settings were default. So if you want "more action", just change stiffness and the other parameters. And of course you could change your animation speed and/or the vertex locations to your needs. Although changing the subdivisions will change the cloth behaviour! Have fun!
