HOW DO YOU DO THIS IN LW: Flag on a Pole (Model Included)

How do a cloth simulation of a flag using standard Lightwave?
I want to do a cloth simulation using standard Lightwave.(8x or 9x)

I am working on animation that includes a flag attached to a pole.
The idea of the simulation is that the movement of the flag is determined
by the movements of the wodden pole and wind "events".

To aid the discussion I have included a simple proxy object.

Looking forward to your comments and ideas.

I've just been doing some flags and banners in a Maya project and had to use Maya 7's cloth (which bites). So I reverted to what I knew and did it in LW, then converted it. Will try to give this object a look and a go.

OK here is the scene with no collision detection.


Ok I updated a bit the object and also added the animation scene.
Here is a link to the flag animation with no colision detection
>>LINK<<
and here are the settings for the controls
>image1
>image2
>image3


Ok so now do I set up the collision detection to the pole?

Hi Roberto,
I was playing around with a similar scene not long ago, and I had a look at your scene and this is what I reckon you could do.
First I tried upping the bounce/bind power on the pole, but I was getting some nasty jerky results. The other option is to take off collision, and put cloth FX onto the pole, with fix all on, and collision set to alll. up the bounce bind power...
the other option which i found worked better, was create a collision null, set to bounce, square shape. then stretch the null till it resembles your pole, but a little larger. then up the bounce bind power to 250% ish... then match the nulls position to the pole and parent it top the pole. calculate, and bang you should have a decent collision.
If you want i will post some screen shots.
