Cloth modifier question...

[Deetee]

Hi guys.. I need help in cloth modifier...

Below is the pic im working on...

as u can see my curtain (applied with cloth modifier) are only partially get direct expose to the wind, and the rest of the parts are behind the balcony glass.

 

 

My major problem is that when i run the simulation, the curtain are moving evenly...

I did all the necessary collision... such as ceiling, floor, walls, pillars, balcony glass, frames, sofa... etc...

but the curtain seems to be blew by the wind evenly...

 

What i want to archive is to make the curtain parts that are directly expose to the wind force to have stronger wave while the curtain parts that stays behind the balcony glass have weaker wave due to the balcony glass should be blocked from the wind directly affect it.

 

some may argue that my balcony glass is too short to really block most of the wind impact.

yes, you may be right, but i did some experiment before entering forum seek for help...

I created an empty room with 1 window. the window is unopen...

then i put a plane with cloth modifier inside the room. applied cloth modifier on the room obj and window obj for collision purpose. applied wind force. start simulate...

somehow, the cloth still affected by the wind...

 

 

I guess collision is purely for simulating collision between objects.

How do i tell the wind to not pass through collision object?

Thanks for the link, but the tutorial never cover how to stop the wind by passing the wall.

Try making a non-rendering object thats way thicker than the glass as the thin glass may be gettign missed by the sample size in the dynamics. I think the cloth modifier uses a vortex system, but I may be wrong/

It seems to me that the angle on the wind should affect allmost all of the cloth. Have you tried to set the wind from the other side, to see if it actually collides with the window? From the other side it should affect far less. Also, if you have a really "light" setting on your cloth, it may seem to be affected more than a heavy cloth, so much that it might appear to affect all of the cloth evenly. And lastly, this might be a stupid question; did you add your glass window object as a collision object in the cloth modifier? Because that is probably the wrong place to add it, you should add it as a collider or obstuction or whatever it is called in the wind object/particle thingy. If you add the window in the cloth modifer, it basically tells the cloth modifier to look out for the glass object, but that has no purpose as the curtain is either pretty much straight down or blowing the other way, so what you need to do is tell the wind that the glass object is an obstruction, so it does not affect the cloth sim behind the glass object. At least that is what seems logical to me. Good luck!
