Hey all! Kiera's been kind enough to help me finish and post a tutorial for Poser 5's wind object. The tutorial simply covers what you need to do to set up wind with dynamic cloth, and explains some of the features. I'm still playing with it myself, so the renders aren't the greatest, but it should be more than enough to get people rolling! Paul

Thanks you very much. I don't have Poser 5 yet, but I'm storing all these tips... looking forward to play with the upgrade!

just had a look too, I even understodd some of it, good stuff to know for my P5 day ;) Thanks loads. Rob

understandable tut! :) those gradient lines on the cloth in the last image, are they pic artifacts or color depth thingy or geometry?

Paul Thanks bunches. Ron

Paul, If the Draping function works the same in a Wind simulation as it does in a normal cloth simulation, there's an error in your tutorial. The Draping frames occur before Frame 1 of your animation, not on-going through your animation. If you calculate 30 draping frames and 30 animation frames, all of the draping takes place first. This "softens" the cloth so it's not stiff as a board in frame 1. Still artists may not even need to calculate an animation to get nice cloth in their image because the draping alone may be enough. In the case of your Wind example, I think (not sure at all) that you're giving 30 draping frames for gravity to take it's effect before the Wind force even begins in frame 1. I know the above is correct for a non-Wind cloth sim, so I'm just guessing it's the same with wind on. Phoenix

Still reading, BTW. Very well done. Thanks! Phoenix

Thanks, I have it book marked so i can actually read through it later.

Uh, I may be dumb, but in your tutorial in the beginning you say I created a wind object, exactly how do you go about doing that? Sharen


phoenixamon posted Tue, 17 September 2002 at 7:55 AM

Object menu, Create Wind Force... right under Create Magnet and so on. You're not dumb, just a little blind. ;) Phoenix

LOL, you are right, cause I was just at that window....LOL, thank you....Sharen...LOL

Good tutorial, I am curious about the number of frames needed or not needed to create the effects. If we don't need a long dynamics calculation I'd really like to go that way. Odd you would say blind ... I noticed the graphics to the left of the tutorial were braille, (Didn't try to read it though it's been twenty years since I studied braille) I was just courious as to why? It's effective, but I'm not sure what the connection is. :) Boni

Well done, Entropic! This is a nicely constructed tutorial! -Brian aka - stillgar

Eep! Lots to respond to... that's what I get for sleeping. ;) "those gradient lines on the cloth in the last image, are they pic artifacts or color depth thingy or geometry? " geometry. I'm using a powerful wind force in that scene, because I wanted things to be noticeable. As a result the mesh is deformed and pulled pretty tight. ;) "If the Draping function works the same in a Wind simulation as it does in a normal cloth simulation, there's an error in your tutorial.

" This makes sense, phoenix... I'm gonna jump back in and play tonite! :) ( I'd only been playing for two hours when I wrote this, so there's a lot that's sketchy... I just wanted people to have some way to get wind to work. ) "Good tutorial, I am curious about the number of frames needed or not needed to create the effects. If we don't need a long dynamics calculation I'd really like to go that way. " Like I said, it will need tweaking. I used 30 frames and 30 drape frames, and that only required an hour of calculation on my machine. We'll have to keep the communication channels open to keep refining things. "I noticed the graphics to the left of the tutorial were braille, (Didn't try to read it though it's been twenty years since I studied braille) I was just courious as to why?

I'll see if I can drag her in here to tell you the whole funny story. ;) Paul P.S.: Thanks for the kudos, all. I'll refine things today and see about adding hair! :)

I just wanted to add my "well done." I thought it was very easy to read. Now, I will have to try it. But I am waiting to find out something about the hair. If you do a dress and hair, do you do it all on the first simulation. In other words, do you clothify the dress, then the hair, and then do simulation? I guess I will try and see. Thanks again, Bill


Entropic posted Tue, 17 September 2002 at 3:26 PM

Right now, as I understand things, the Dynamics are all simulated at once. This means that the hair and cloth will both be affected by gravity and wind in a single simulation. Paul

The Braille thing is totally a silly inside joke (and, amazingly, several people have actually noticed it.) =p A web site about digital art with Braille on it (graphical Braille, no less!) is sort of like a drive-up ATM machine.. =D

Didn't attrition.org used to hold an archive of defaced/hacked web sites? Or am I thinking of another "attrition"? later jb

Yep. The owner of attrition.org is my ex-boyfriend and best friend. ;)


Boni posted Wed, 18 September 2002 at 11:20 AM

Cool. I'll keep a close eye on this thread, I'm very interested in how this draping thing works. It's not just clothifying and gravity ... it's fascinating. Love the braille thing. I'm working with the Jobs program for the Society for the Blind in Sacramento and we need to have a sense of humer about ourselves. This new Poser 5 has a wonderful potential! Boni
