Does it dForce?

    Looking into grabbing this outfit in a bundle, today, and was wondering if it's dynamic/dforce-friendly ... anyone have it?

     

    I have it and tried with the top and the skirt.

    I had my doubts regarding the skirt and the frills.

    It didn't just explode, but it is not properly welded, so it doesn't behave properly. And neither did the top - it started to rip apart.

    It might be possible it can be tweeked so it can be simulated, but I think it requires an effort.

    It wouldn't be my choise.

    Thanks ... good to know. Will spend money elsewhere.

    Does anyone have this swimsuit? If so, I'd love to see renders of dforce used on it and the step-by-step settings used for newbies.

    I haven't come across a clothing set yet that I haven't been able to dForce at least a little. The super sekret trick with making non-dForce items work is to use weight map nodes to "weld" together spots that would normally fly apart during a simulation.

    A mini-tutorial here may help any newbies that come across this thread. For example, I know nothing about weight map nodes.

    Some non dforce items respond well to setting collisions off in the surfaces tab. Not at always, but it can prevent some explosions.

    Oh, that's a good tip.  I'll need to try that with the zipper of https://www.daz3d.com/fg-mega-hoodie-for-genesis-8-female-s.  I wanted to dForce the hood, but the thing kept flying open along the zipper.

    If you give it a go, Sevrin, I'd love to see you add your process and wip renders here in the thread. :)

    So, I decided to take on Mec4D's Wrestling Singlet.

    I find that DAZ tends to have problems with "strappy things" around the torso, as they often follow the breasts/pecs in a manner that real straps wouldn't. Like so:

    It probably didn't help that the above example uses auto-fit to put this G2M item on a G8M. But even in the promos you can see some awkwardness around the pectorals.

    So, dForce. Here's the scene before the animation starts:

    Freaky! surprise

    And here's the result:

    Gotta say, I'm very pleased!

    (I did get some minor cases of awkward geometry in some spots which I corrected in post.)

    dForce surface Settings
    Friction: 0.2
    Stretch Stiffness: 0.01
    Self Collide: OFF -> this avoided some mini-explosions that I would otherwise get around the garments edges.

    We need a soundtrack for this forum... when I look at those pictures I hear Tim Curry singing "In just seven days minutes I can make you a man..." in his role as Frank'n'furter ^^

  • You can easily see if any item in your collection will play nice with dForce simply by turning on wireframe shading and looking at it. If it has mostly quads and they are spread out nice and even then chances are you can thow dForce on it. If you see a lot of triagles or other non quad stuctures in there though it will probably not work so well. Of course it's ust a general rule of thumb and exception can and will happen. Oh, also make sure it's a single mesh and not different meshes combined to look as one mesh.

    You can definitely use tri-mesh with dForce, just turn Bend Stiffness down in surfaces. Usually .30 or lower will keep it from exploding. Is also a good thing to try if you have quad mesh items exploding.

    I could swear that was in English ... but all of that quads and mesh talk is not something I ever had need to know or learn. I don't suppose a few screenshots would be doable?

    Does MMA Shorts for G2M dForce? Well, yes... kinda sorta.

    It's clear that the item is not meant to be dForced. The simulation takes quite a long time for what should be a simple garment. The result has some awkward geometry. Some of that you can lessen with a smoothing modifier. But turn up the values too much and the whole thing explodes.

    The slits on the side of the legs don't help, either. In my below example there's this weird little flap on the left leg that won't go down no matter how long I let it stabilise.

    Despite all that I still think the garment looks better dForced than without.

    Only autofit:

     

    Autofit + dForce

     

    Autofit + dForce + Smoothing Modifier

     

    End result with some minor post work:

    Thanks for sharing that with us ... Being the lazy sort, I don't see me acquiring it for the difficulty to drape reason ... But you did an amazing job with it, regardless.

  • WillowRavenWillowRaven Posts: 3,787

    I like to see if anyone already has a product and has tried to drape it before I buy it when I see it on sale ... Does anyone have this outfit? And if so, have you tried to Force it? I'm not concerned with the shorts as much as the top an the belt. Is it all one piece? Kinda looks like the shirt's 'tail' is 'under' the belt. Am I seeing that right? Or can the shirt be worn and draped separately?

    According to the file list it's all one item. You could drape just the shirt part with some material settings/weight mapping though.

    Oh, I wouldn't aquire it for the purpose of dForcing it. But it was a freebie a few weeks ago so I imagine many folks have it.

    Honestly with that many straps, ropes, pouches, belts, and fasteners - I doubt it would dForce well without a TON of work put into weight mapping all the bits and pieces.

    If it's trias that are the dForce problem you might consider exporting os obj to Blender (in t-pose) and using Blender's function to combine triangles into quads and then reimporting that to DS and transferring the rigging, surfaces, and whatnot to the 'Blender quadrified version' and dForcing again. I've not tried that myself though.

    As Aave_Nainen mentioned, turn bend stiffness down to 0.2 for any non-dForce clothing item. Also set the surfaces of any collars, belts, cuffs, or pockets to a dynamics strength of 0 for the first try. This almost always makes it feasible to use dForce.

    If you haven't already discovered it, my discussion thread has 86 tutorials on using dForce. First post is a table of contents and the second is an index.

    Your thread is an invaluable tool with countless hours of work and research that has gone into it. Thank you SO MUCH for all the work you've done to help the community learn about what dForce can do. It's awesome of you to share your work and discoveries with the community! heart

    thanks 3Diva, glad it helps folks learn dForce

    Apropos of nothing, Adam Thwaites' free Warrior Outfit dForces well as long as you set the layers correctly. The bodysuit is layer 1, the skirt is layer 2, the belt buckle is layer 3.

    Good to know - and the render came out great!

    I did dforce this outfit somewhat in this image,  mainly the skirt area but some of the other areas as well, I did have to weight map it with different levels and it does ok but it did take some work.

    You guys... Weight Maps!

    This was probably obvious to most, but I only just now discovered it. Now I feel a little stupid because 1) it's really quite essential, and 2) it's really easy to use.

    (Also, it makes me wonder what I bought the dForce Magnets for.)

    This video explanes it really well.

     

    So, does the Mistress Arachne Outfit dForce?

    Yes, but only if you weightmap it.

    In my example only the front flap is affected by dForce. The back flap poses well enough without dForce and the rest of the outfit is form fitting anyway.

    To keep the front flap from falling to the floor, use weight mapping to disable dForce on the upper part.
