I was playing with Entropics wind tutorial and got decent results I scaled the cloth drape so it was only about the size to fit between her breasts and belly. Now my question how do I keep it from dropping around her feet? Does it all depend on the placement of the cloth when you start the simulation? I placed it approximately the same place he did when I started. Going through the frames didnt give me the same nice bend in the cloth I got at the end. Parenting to the chest didnt seem to work either.

Try setting drape frames to 0 if you haven't already. See if that helps.


Tammy ( ) posted Wed, 18 September 2002 at 12:54 PM

Thanks Kiera Ill give that a try. When I lowered the drape frames I didnt seem to get that nice interaction with the wind deformer but I was probably doing something wrong. Thanks for your help.

Another option is to try increasing the cloth's friction. So far cloth seems like a black art. A lot of experimentation to get the desired results. ;)

You might want to try setting the static friction coefficient higher. More static friction will mean less falling off of the figure... I recommend playing with both friction dials to see if you can get a good result. :) Auralia

Cool thanks Ill give that a try too and experiment with the settings and see what I can come up with. If I come up with anything decent Ill post the results and settings.

Excellent. :) There's also some possibility that you could constrain a part of the cloth to the figure in order to keep it from falling too much, but I don't know how well that will work, since it may look like it's pinned to her body. Of course, in a strong enough wind, that may be the look you're going for. Ahh... experimentation. I definitely look forward to seeing your results! Auralia

Heya! Glad to see you're working with the tutorial! Here are my suggestions after playing. 1. Increase the force of the wind by moving the intensity dial up. While a hurricane gale of 20 might not be required it's good to find the extremes and tweak as necessary. 2. Static friction and dynamic friction settings will help sliding. I'm going to go out on a limb and say that setting these at maximum under low wind conditions will create a clingy effect that means touching parts should stay touching. 3. In conjunction with 2, or as a stand alone, try decreasing the cloth's density. Poser should use this to determine the amount of force pulling the cloth down. Less dense materials should be less affected by gravity, while more dense will be affected to a greater degree. My comprehensive tutorial is on the way in the next four or five hours, and if you think it's getting interesting now, I'm already thinking of how to take these "black arts" to the next level... Wind is a fluid dynamic meaning it works exactly the same as water and fire, and from what I can see, the wind object can be rendered with textures... This one tool may be the key to a fully functional special effects lab within Poser! Combined with the crazy ways we can think of for making clothification effects simulate more deep interactions on non-cloth objects, and the possibilities for strand-based hair ( who says it has to be hair, after all? Why not just call it dynamic strands? ) things are about to get intense in Poser land, that's for darn sure. =D Paul

Thanks for your help I played with this today and came up with close to the results I was going for it was allot of fun. I went with 15 frames, which took around 10-15 minutes to simulate. I found out the best thing I can do is leave and let it go, gave me time to fold laundry anyway :)because my computer doesnt like cancel simulation too well. I placed the cloth plane just slightly above her head at the same angle Paul had his. And Ill post images of my settings below. On the second one I just made it 50% transparent and set the color to blue in the material room just to play and see what it looked like partially transparent.

Here is the first image with the settings I used.

And the second

It's too bad that P5 didn't put a scale control with the dial controls. It would make this process much more intuitive.

A scale control could indicate the low and high limitations and also come with preset buttons for memorizing previous settings.

Heh... not to worry sittingblue, my comprehensive overview is being formatted and uploaded even as we speak, with value explanations coming in a day or two for reproducing real life items. :) Paul

material on wind? DOH! Hadn't even thought of that. That opens amazing possibilities! Tammy, looking good. Thanks for the screenshots

Paul, Why do you say "Less dense materials should be less affected by gravity"? Either I don't understand what you are saying, or you are saying something counter to how the real world works. The classic college discussion of dropping various objects from the Leaning Tower of Pisa: a cannon ball would fall at the same speed as a light object if gravity were the only factor - but there is also friction with the air, so sufficiently light objects get slowed down and take longer; e.g. a feather. But that isn't because gravity affects the two differently - it doesn't. Sorry if I am taking you too literally, maybe you are just saying you want SOME parameter that changes how fast an object falls, whether we blame that on gravity or on air resistance ;-) -- Toolmaker Steve -- ToolmakerSteve
