But since the sitting pose needs to be indented into the stool cushion is there a way of using some dynamic indentation tool like bullet physics? and dynamic simulation simultaneously or for that matter sequentially?
No (or not yet, Daz has said this cloth simulation is only the first step). You could use a dForm or other tool to pre-indent the stool, however.
You may be able to do this in two steps: add a dynamic modifier to the chair's cushions, set gravity to -0.10, run the simulation, then freeze the simulation on the chair (whether this would work depends upon how the chair was constructed - best if the cushion is a separate mesh. I used negative gravity to lay a figure's head into a pillow). After this, raise the figure slightly and now try draping the clothing.
Could you briefly explain the steps to perform the Dform indentation please?
LOL, my bad. Ok, sorry.....
That rather depends on the model, and on how precisely you wish to mimic reality. At the simplest select the stool and Create>New dForm, which will parent the dForm to the stool. Select the Field and scale/potion it so you get the vertices on the stool seat showing green-red with the erst of the stool not showing any effect, then expand the base, select the dForm node itself, and translate it down a bit to generate the dent.
hahah I was WONDERING why that dress was trending over at the Rendo freebie page even though the dress had been out for over 2 years. Now I know why. lol :)
Funny, right? Wish I'd have waited a couple years and not bought it. I can have it for free now. Oh well...
... But the freebie dress is licensed for non-commercial use only.
Greetings,
Oh my gosh, I just realized that dForce means I can actually buy those pose sets (like 90% of them!) where the characters are always touching their sides, their legs, their arms, etc... I used to not be able to buy them because they'd ALWAYS mess up with clothes, but now (in theory) if I apply dForce to the clothes they'll drape around the self-touching.

Actually you need to be careful when hands contact other parts of the body with dForce. It can result in the hand pushing the fabric into the body, or worse, a complete explosion of the fabric. It is best to adjust the pose so that the hand does not actually make contact so that the fabric has a small space to sit between the hand and the body. It's a similar situation to the sitting issue that is being discussed above.
Another experiment with dForce and the pillow.
Will need to further refine that scene.
I had DS completely shut down to the desktop without warning the other day when I forgot to move the hand off the hip slightly to clear the cloth. Started the sim, then bam. Shut down.
Looks really good and the pillowcase edges are nice the way they are falling.
Thanks, Sapat. I am trying to create a weight map for the pillow,
that allows the character volume to interact with the pillow during simulation.
Does it not work on Genesis 2 or older?
I just tried to Dforce on Platinum Cocktail with Victoria 6, https://www.daz3d.com/platinum-cocktail-for-genesis-2-females it simply did not work at all. It just ran 1% then DAZ froze.
That will depend on the clothing, not the figure it was made for.
So what does that really mean? That Plat Coctail does not work? How do I see that before starting? Can I even do that or is it a trial and error thing?
At this point, yes it may be trial and error for most. In some cases I think some more experienced users may be able to take a look at a mesh and know what might indicate a problem, but that is also the reason for this thread: https://www.daz3d.com/forums/discussion/207066/dforce-verified-functional-clothing-out-of-the-box/p1 to discuss items that others have already tried. I do not have that specific dress to also try to see if I get different results. I occaisionally would get crashes on one try, then after restarting and checking that there isn't anything in the background using a lot of memory, have the same item drape sucessfully.
Coven gown simulated with dForce on Olympia 6. Changed to iray shaders, because the original material was too dark.

With more extreme pose, the gown begins to look no so good (on the lower part of it).
Agreed it starts to lose integrity, but with the other poses it seems to hold up.
Real fabric wouldn't stretch that far either.
LOL, yep, there would be that embarrassing moment when you've lost coverage in an area where you need it!
If I recall correctly, Platinum Cocktail consists of two parts, a lace dress and an opaque slip. It could be that during the simulation, they intersect. If you simply applied the dForce modifier, both parts would have the same "Collision Layer" designation. Setting the dress to a higher layer might make them work together. I've got some other ideas, too. I have that dress. I'll give it a try and get back to you here.
@Hera, I found the problem with the Platinum Cocktail dress. The slip drapes without any issues. It's the dress that is exploding on you.
The dress has three material zones: DressFabric, Sleeves, and ZipperPuller. The ZipperPuller is the culprit. Remove it from the simulation, and the dress drapes without issue. I simply set Visible in Simulation to off and was able to drape the dress.
I left Collision Layer at "1" for the slip and set Collision Layer to "5" for the dress. Not sure if that was necessary. I tested the drape with Self-Collide both "Off" and "On" and it still worked. Self-Collide "Off" produced a nicer result.
I did all my testing with G2F in the T-Pose as the skirt of the dress and slip are not conforming. I have not tested an actual pose, but I am assuming it will be necessary to set Frames To Simulate to "Animated (Use Timeline Play Range)" (In the Simulation Settings,) to get this outfit to drape with a posed figure. I'll try that next, but I wanted to get back to you right away about the ZipperPuller.
If the memorised pose (which is often the A or T zero pose if you haven't changed it) fits the dress then drape from memorised pose should also work.
I may have missed if this was commented on elsewhere, but it seems (and I haven't done any sort of imperical testing with say the MFD or anything) that the drape proccesses faster with older figures. At least it seems that G2 proccesses faster than G3 which is faster than G8...
Anyone else notice this? Or is it just a weird conicidence based on what I'm testing with each figure?
I haven't noticed, but I wasn't looking for it, either. To be sure it's the figure, you would need to use the same clothing. But then there is the potetial issue of time differences caused by fitting the clothing of one generation to another. Regardless, I'll pay more attention to the simulation time now. lol
I hadn't thought of that. lol... However, I'm sure it would also depend on the pose. The pose I wanted to use would have had the hands passing through the dress. Won't that cause an explosion, too?
Anyway, I did some renders of the Platinum Cocktail after posed.
This is G2F Base Female:
This is with the default dForce material settings, except with Self Collide Off, (and the ZipperPuller hidden.) I used the Animated setting for Frames to Simulate, 61 frames. Frame 0 is T-Pose. Frame 30 is target pose with modifications to the arms with them up and out a short way from the body and each other. Frame 60 is the target pose, with the shoe pose applied and foot rotations set back to match the target pose.
If I were using this in a scene, I would use weight maps to secure the sholder straps a bit more firmly in place for both the slip and dress. I would also lower the weight a bit around the neckline of both. And I would lower the Dynamic Strength of the dress to .9 or .8.
On the back, there is an issue with the "zipper". Unless you need the back of the dress showing, I'd just ignore it. Here's a closeup:
The "zipper" doesn't seem to distort much, if at all, from the Upper Abdomen down. But distortion gets worse the further up the zipper goes, doubling it's width at the neckline. The ZipperPuller, made invisible to the simulation, has moved to the left and down. If the dress is going to be seen from the back, weight mapping can be used to lower or remove the influence of dForce from those polys.
Finally, here is a side-by-side comparison of the same dress and pose on Lilith 6, G2 Base Female and Teen Josie 6. The arms would need some adjustments for Lilith 6 or Teen Josie 6 for this pose, but this gives you a nice comparison of how well the dress drapes on both a more ample figure and a less mature figure.
