It does not have to be the same as the actual physical properties as long as it resembles the actual cloth behavior.
However, simulation settings are more intuitive and easier to operate if they resemble actual physical properties.
Linear spring constant (?) with no fixed upper limit of elongation cloth may bounce like a yo-yo when hung from a high place, a movement that is unfamiliar to us in everyday life.
When you try to set up a setting to suppress the unnaturalness, a new and different unnaturalness is created, and you may end up going in circles.
The current simulation settings for creating animated movies with dForcs cloth are so difficult just to keep it from exploding that I don't have the luxury of pursuing the texture of the cloth's behavior.
In some cases, I have to give up even the animation motion I want before the cloth texture.
In the case of long animated movies, even if explosions can be avoided, various energies can accumulate in the cloth, and the geometry can become tangled up in a mess.
It takes time to check the simulation results, and it is very difficult to find a compromise between the simulation settings.
I am willing to go through the hard work of creation, but the struggle to find a compromise in the tools is sterile.
If I were creating a still image, I would have fewer problems because I would not be able to see the motion behavior.
Hope in the future perhaps Daz 5.0 or in a future update there will be some similar simulation like there is in Marvelous Designer which is in "real time" so you can adjust the clothing easier!
The fact that the dForce fabric stretches without limit seems to magnify the unnaturalness of the fabric.
It cannot limit its ability to stretch abnormally when fast movement or high wind speeds are required.
It seems to me that there should be an upper limit to the stretch rate of the fabric.
I would like a parameter to set the maximum elongation rate.
Thanks for the reply.
I have been trying to change various Surface parameters and animations, but with not so good results.
Sometimes the elasticity is too strong and it bounces around and sometimes it moves in a way that doesn't seem like cloth.
Sometimes the garment jerks and vibrates unnaturally, even when the person is standing still.
Even if the wind is very strong, it is also not good for the hair to grow long in strong winds.
Also, it may depend on the product, but some parameters may freeze if the value is raised above a certain level, which may limit the adjustable range.
I use a relatively fast graphics board, packed with large VRAM, and simulate one item at a time, but I cannot avoid this problem.
If I'm making still images that don't animate, I only need one frame to complete the process, which reduces the problem.
I have adjusted the dForce hair stretching and the velocity-related parameters, but my hair still grows long in strong winds.
If the dForce simulation is repeated many times, some noise data may remain on the garment.
At that time, no matter how many times the Clear button was pressed, it did not return to the perfect initial state.
Sometimes when I run the simulation in that state, the polygons partially collapse.
In such cases, you need to delete the garment and dress it again.
Yes.
Strange.
It takes a lot of time and effort, but it can be cured by re-dressing it, so that's how I get around it now.
dForceの爆発はかなり大きな問題です。
爆発のせいで、思い通りのポーズが取れなかったり、dForceの使用を諦めざるを得なかったりすることが多々あります。
これは特にアニメーションにおいて当てはまります。
今回の場合は、静止画ではありますが、パラメータを何度も調整して試した結果、スカート部分にdForceを使うのは諦めざるを得ませんでした。

Because of the explosion, dForce was still not available for movies.
The reality is that we spent more time trying to see if dForce would explode than we spent working on the motion.
I wanted the skirt to hang downwards by gravity, and I also wanted the wind effect.
It's a shame.
Dforce is kinda working for stills, but for animations it is way to unpredictable.
Sometimes for unknown reasons, it even doesn't follow gravity, but is just floating around randomly.
since this thread was dug up
it's a lot less forgiving than Virtual World Dynamics for example
but since that only works for me on my Win7 PC which is now having issues I am stuck with Dforce
I do do animations with it, lots of them but it often requires a lot pf isolating of mesh, weight painting using the node for Dforce hiding of body parts and animations that don't intersect or even come near to other body parts
...Wendy, thank you for that information about the VWD software as I am still on Win7.
I just download the free version of VWDClothAndHair Demo V1...
With dForce I have been experiencing issues with it crashing my display driver from time to time. Not sure if it is the older OS or the fact I am using a 3 generation old GPU (Maxwell Titan-X and Nvidia driver 471.41 which is the last stable release that supports WIn7)
Normally an error during a simulation would simply result in the Daz programme crashing to the desktop. However when the display driver crashes it requires a full reboot of the system to restore. With just about all clothing being dForce these days, this issue makes a large segment of my content library rather useless.
As the VWD Cloth and Hair software specifically lists Win7 ( ane even Xp), It makes me wonder if that may help with the issues I am having with dForce.. Unfortunately Version 2 is expensive (60 USD) but at least with the demo I can give it a try before having to scrape up the funds for the full plugin
