Subject: "Grab" dynamic cloth - help


coinsrus ( ) posted Mon, 22 May 2006 at 1:58 PM · edited Fri, 29 November 2024 at 8:19 AM

I am trying to set a pose where a dancer grabs onto the hem of a dynamic skirt. So far I have not been successful.

Does anyone know how to have a character hold, grab or move dynamic clothing, or be able to point me in the direction of a tutorial on the subject?

Do you have the cloth set to "Collide" against that figure's hand?


coinsrus ( ) posted Mon, 22 May 2006 at 2:06 PM

Yes I do. However, trying to pose it tends to lose the cloth - if the hand is not right up against the cloth there is no way the cloth knows it is being held.

So what you're saying is that the cloth slides right off the hand. Increase the settings in the friction area and maybe decrease the length of the simulation so that it stops once the cloth is within the grip of the hand.

I'll try that. Thanks.

you can try coreographed group in the simulation.

when seting up the simulation allocate a few vertices to the coreographed group. This group can then be keyframed for movement. When the cloth simulation is run the movement of the coreographed group will be included.

There is a tutorial on Daz website that may help demonstarte the process.

Sounds interesting! I've never even used choreographed yet. Do you have a link to that tutorial handy that you can post?

Do you have a link for the tutorial? I tried to find it and failed.

Ummmm - I've done this before (for a still pic), but forgotten exactly how... (and I didn't keep any notes on how I did it, I was just playing around at the time..)

IIRC, it involved something like:
Got the skirt draped on zeroed figure, so it fell naturally (using real sim, not draping frames, draping frames are added BEFORE frame 1, so if they go wrong they can't be corrected).
Saved skirt at sensible-looking frame as .obj, exit & restart Poser. (This was to clear up memory, I didn't have much at the time.)
Reload (and zero) figure. Load the save (draped) skirt.
Go to approx frame 15, set up final pose for figure.
Return to frame 1, and contort the figure so that it can reach down and get the hands under the skirt. As close as possible. Don't allow anything to intersect - stretch arms, make any wierd pose, it doesn't matter - just get the hands under the hem without anything intersecting the cloth.
(I then ran the anim to make sure that the figure returned properly to the final pose.  Sometimes you get limbs going in silly directions - it's best to check first. If that happens, add a few key-frames to correct the situation).

Anyway, once all was set up (and I'd saved scene again, in case anything went wrong) I returned to frame 1, entered the cloth room, clothified the (new, draped) skirt, and constrained a couple of verts of the skirt near the centre of each of the palms.

Ran simulation. Worked OK.

IIRC, that is. To be more specific, I'd have to try it again...

Hope that helps,
Cheers,
Diolma

Try this one (worked for me).

Hi, E-Bob:-))

Just looked at the tutorial you linked to. Nice Tut.
However, if I decided to try to do that, I wouldn't quite do it that way...
What I'd do is more-or-less the same, except I'd do it on a horizontal figure (with a horizontal cloth/towel, and all movements changed accordingly). Then change figure (and towel) back to vertical... (probably with lots of saves of both scene and towel en-route..).
And then possibly try a second simulation with constrained groups changed (to the "top" of the towel)...

 Neat idea...

Cheers,
Diolma
