dForce clothing to make clothing fit better?

Hi,
I was trying to make clothing fit better in the female chest area, in particular that silly indentation in between the breasts.
For that I used a dForce shirt and enlarged the breasts from 0 to bigger over 30 frames in the timeline, expecting the dForce simulation to push the shirt more or less uniformly outwards.

Well, that didn't work as expected.
Even with collision detection set to very high, the breasts would eventually just poke through the shirt.
Am I doing something wrong, or is that just a dForce limitation?

Thanks!

    Sweet - thank you so much! yes

    You can also use Fit Control to offset the breasts then do a simulation if you have it. It actually comes in handy for Dforce cloth as well.

    Thanks, I'll give that a shot as well.

    I looked at that tutorial and - for the life of me - I can't find where you adjust dforce friction, stiffness and such.

    I obviously haven't played much with dForce, other than Simulation Settings. And I did find a threat that explains how to run the script to get the dForce menu, but all I can find
    is the "dforce Surface Adjuster" besides adding deformers.
    What am I missing now..?

    Wow, I finaly found it in the Node Surface parameters..
    Not sure if its that obvious a place to look for it, but it sure would have been nice if that was mentioned anywhere in that tutorial.

    You may need to make the shirt stretchier by adjusting its settings in the Surface pane, or using the Surface Adjuster script from the Surfaces pane option menu.

    Thanks Richard. I'll try those parameters.

    Part of what adding the dForce Modifier does is add a bunch of parameters to the materials of the object being simmed. Just like normal materials, these properties can be found in the surfaces tab. That is what is meant in the tutorial when it says "Set the Friction for the shirt mats to .001".

    If you haven't checked it out already, Rob took the time to post some very detailed documentation on dForce, which can be found here:

    Hope this helps.

    Thanks Greg.

    Yeah - I can tell that this will require a lot more research than what I had hoped for.

    A Quick & Dirty(tm) clothing fix - not so much..

    Hmm.. not sure if I'm missing a step or doing something wrong, but my results following the tutorial have been rather underwhelming so far.
    Certainly nothing even close to the top left image in the tutorial, with its total absence of an indentation between the breasts.
    There is a difference after I'm running the simulation, but I'm not sure it is any better that just using the smoothing modifier. Maybe even worse.

    Does someone have an example of using this technique other than the images in the tutorial?

    Hi Richard,
    The surface adjuster script - those values are reset to zero every time it is opened? Where can I tell what the current stretch value actually is? In the Surface tab?

    First of all, the top left image in the tutorial is a base G3F wearing the shirt, the top right image is my custom morph dialed in (and the shirt clinging), and the 3rd image underneath is after simulation on the shirt.

    I took the time to follow the tutorial myself using Shiloh as the morph being dialed in on G3F and the Delta Dress as the clothing item. The 3 images below are a base G3F, Shiloh dialed in, and finally the simulation on the dress included:

    Seems to be functioning as expected if you asked me. As you can see, the clinging up top has been fixed, but there are some other areas where the same procedure needs to be applied (which I didn't do in this quick test).

    I'm confused.. There is next to no indentation between the breasts in the top left image in the tutorial.
    As far as I'm concerned, this image looks the best to me in that regard.

    I will play around it some more though. Do you have another example without a cutout?

    The top left image in the tutorial is a base G3F with no morph applied, so of course it’s going to look the best because that is what the person who modeled the clothing was using as a reference.

    Sorry, but I’m not going to stop what I’m working on again to do another example. I’m not sure what good it will do, as I obviously am unable to explain things to you - maybe somebody else can.

    Those are not absolute values, they are adjustments to the initial values which will be applied when you click Accept. You can see the absolute values in the Surfaces pane

    Got it. Thanks Richard.

    Do you have an example of this using Fit Control?
    I am mostly concerned about the center indentation.

    Thanks!
