I have a model of a kind of new age cowboy with a black trench coat that hangs done past his knees. The torso part of the coat is a skin but the part that hangs down is a model. How would I be able to let it blow in the wind and move realistically like the scarf that the ninja wears in the PS2's Shinobe.

I think that the hanging down part of the coat would have to be another model that is attached through coding though.

Please help.

I have the Commercial Edition.

That could be done with A6 Pro, but A6 Commercial only has 1 physics entity and you will need lots to move the coat around in a realistic manner. Basically create invisible physics entities and update your coat MDL vertices with the position taken from these invisible entitites.

Let me save you a ton of time:
Can't be done; at least not with the Commercial PE and I don't even know that the Pro PE could do it.

Sorry Bro.

Marco's idea is very interesting, but sounds very difficult to impliment. I'd like to see it done though.

I animated a dress using Lightwave's motion dynamics then exported as point animation. Even then, it is very hard getting it so that the material stays out of the rest of the model.

MED doesn't have motion dynamics, so you'll have to look around for an application that will do the job for you.

It would be very nice if Game Studio had motion dynamics built into it. Maybe something to suggest for Engine Future?

Do you think that Newton physics would do it?

My guess is no. It's a pretty challenging problem you are addressing.

How about just animating the Model of the tail of the trench coat, blowing in the "wind" (giving it a long sequence so it doesn't look looped in the game), then attach it to the body of your player (I'm no good at scripting but) somehow make it so that when you move foward to top of the tail peice is hinged to the player thus making the bottom of the coat slightly flare back in movement. You could even use a hinge from newton.

Absolutly. Then the cape is just an animated model and you can do whatever you want.
It's tieiing in real time physics that presents massive problems

This probably won't help you out much, but here is a link of a cloth simulation demo from some website I found quite a while back. Way too hard for me to learn/do. But the demos are fun to look at. http://apocalyx.sourceforge.net/modules.php?name=News&file=article&sid=2&mode=&order=0&thold=0

Why not assume there is no wind? Then the cape will only move when the player moves. This could be a lot easier to set up then the alternative. You're player will run forwards, turn, and stop. Those aren't that hard to set up animations for as long you're going to use the same animation over and over for these states.

Although, I am assuming you've got access to a cloth simulator, which is a pretty good sized assumption.
