# Wind force field not working

I am trying to get a waving effect for a flag in my animation I am working on. However when I click alt a the cloth fabric just hangs there not being affected at all by the wind. I have wind power at 163 and it is aimed right at the flag yet it still does not work. http://www.pasteall.org/blend/27552 is the link to the file.

• I too have this problem , Please help me out. I have attached blend file : pasteall.org/blend/31250 – user5821 Aug 29 '14 at 16:58
• Supplemental: Wind needs to be in the same layer with the cloth. – SVAFnemesis Feb 24 '16 at 18:27

I am not sure what exactly the problem is but this is my guess. You need to decrease the mass of the flag. By default it is quite heavy.

• Its set to the silk preset with a mass of .15 – user2389 Mar 14 '14 at 15:20
• Ive tested it in new windows and it works just fine but for some reason it does not work in this file I've created. – user2389 Mar 14 '14 at 15:21
• If you want to upload the blend file I can take a look at it, – Vader Mar 14 '14 at 15:22

I've found that the cloth seems to need to "drop" completely before it will be affected by the wind. I tried a plane hanging from the top edge and because it was already in the "dropped" position it animated straight away with a wind force of 2000 to 9000 it flapped nicely, 10000 made it go nuts. I tried with a cloak next, much more complex, and after pinning it, it took 100 frames before I got some ripples with a wind force of 9000

I had a similar problem, and my flag started to react to the wind force once I scaled it up 10 times.

The bigger the flag was (in Blender Units) the more it reacted to the wind force.

(my problem was: too low strength and too big falloff power).
