Subject: cloth and wind

I'm trying to make a piece of cloth look like it's blowing in the wind.  It's just a plane that's been subdivided a bunch of times and pinned at two corners, and when I run the cloth simulation it falls and hangs by those corners.  I want it to also look like there's some wind from right to left.  I can sort of get this effect by having gravity along x or y as well as z, but those are constant, so they get into a stable state and just stop and it doesn't seem to be possible to animate them.  I've also added a wind physics object, but it doesn't seem to do anything to the cloth or even to particles.  Is there a way to get the cloth to react to the wind?

Only thing I can think of is.. they need to be on the same layer.

I just tried it and it works for me.  Not sure why it's not for you.  I emailed the file to you.

It also looks like it's 'baking' the cloth animation and there's no bake button.  I removed the wind plane and the cloth still flaps in the wind.  If you go into edit mode and back out on the cloth, it seems to reset the 'bake'.

You might have 'baked' yours before you added the wind.

by a wind physics object, (this may be something I haven't come across - still a newb in many ways) do you mean an empty with a wind added?

this is how I did things and it's worked first time....

Will try and stick a link to the blend file in a few minutes (ftp proggy is playing up:( )

Man, I totally forgot about this project, I found it again while filing old emails.  Thanks for the help, guys, I'll have to play with it again :)
