Help using Dynamic cloth! (scale and cling)

Testing6790

Hi all,

I have all of opitex's freebies that I can get my hand on as well as the essentials (I think?). I'm trying to use the bikini one. Pretty simple, right? Wrong! The bottoms just... slide down the figure. I've tried increasing the friction, reducing the gravity and even doing negative gravity! This isn't just with the bikini, it's just that this one is the straw that broke my back to create the post.

I also have a problem having dynamic cloth keep scale. Like if I have a very thin character I apply some Z/X scale reductions. Maybe I want a longer / shorter skirt. Apply Y scaling. When I drape they all stretch back out to maximum scale, even with very few pressure surfaces intersecting the geometry. Sheer resistance seems to do nothing.

Thanks for reading!

This sounds like you're applying scale settings in the Parameters tab. That works for pre-drape setup of the cloth, but as soon as you start the drape the cloth snaps back to its original scale. What you need are the Shrink X% and Shrink Y% settings in the Dynamic Clothing tab Panel sub-tab. It's fiddly to begin with, but once you get used to it setting a shrink factor is fairly straightforward.

Note that there isn't a Shrink Z%, this is because what you're doing is shrinking the layout of that material as laid out on the UVMap — all you can do is make it narrower and/or shorter.

Also note that because the shrink is relative to the UVMap, which way round the shrink goes depends on which way round that material is set on the UVMap. Some materials are upright, some rotated or upside down. The Optitex cloth is designed by a program that makes cloth patterns for real clothes, and sometimes it shows in weird UV layouts.

With Optitex Dynamic Clothing it is probably easier just to resize everything else. The bikini will probably fit any figure which is the same size as Victoria 4, for which it was designed, but a slimmer figure will suffer the indignity you have described. So scale everything else in the scene up by 10% or so. The quickest way to do this is to select everything bar the dynamic clothing and create a new group which you can then rescale in one fell swoop, and this should retain all the relative positions.

The hoops one needs to jump through! If only dynamic cloth didn't look so much better when used well. Alas, poor me!
