Im having trouble getting my softbodies flag to wave like it should be.I would like to know what effects goes into making a flag wave randonly side to side and even up and down a bit.Iv'e been using a fan effect with a gravity effect with not so good results.My fan effect just blows the flag forward but i would like the flag to blow back and forth.Also the gravity part just pulls it down.Iv'e been looking for some setting in the attribte editor that will give it a random effect but i dont see that.Any help would be apreciated.

If you are using goals for your softy, you would need to animate the general motion of your NON-soft goal object, and your "soft" flag would follow along, taking on the general movement of that animation, and also benefit with your fan field as well.

Hope that made sense?

No problem!

Also, make sure to check the docs regarding "Painting Goal Weights" so as to help you paint the areas that you want to be more wavy user added image

(i.e lighter grey means less weight, black means 0, or stiff.)

What version of Maya are you running?

(Note: this is important, as there is a step-by-step flag tut in the 4.5 docs that I found user added image

Either way, if you check out this page in the docs, your problems should be solved:

Go to: Dynamics - Soft Bodies - Paint Soft Body Weights Tool

The example on this page shows you how to pretty much paint weights on a hanging drape, but the same idea applies to a flag user added image

Good luck!

PS, that way, you don't need to worry about springs unless you want to user added image
