Spring Dynamics is fantastic! I think this is a game-changer for people who like to do animations! I've been wanting a product like this in Daz Studio for a long time! This is great! Thank you, 3D Universe, for the amazing product!
Here's a quick animation test with Spring Dynamics (I added it to the hair fringe and the left and right pectoral). Rendered at lighting fast speed with Filament.

Thanks for showing us the results, 3Diva. Just a question: did you have to add the bones consecutively or does the script work if you select all of them at once? I tried yesterday but was unable to see results, as I was having trouble with my computer. Also (I lied: two questions), did you see whether it handles collisions at all? I am guessing it doesn't, but one can still hope.
You can select multiple bones by holding down Control while selecting them. :) Holding control, I selected both pecs and then each bone from the hair fringe then ran the script.
Here are the settings I used:
It only does movement, so collision isn't part of it. However, you can probably add a smoothing modifier to the body to create collision effects. I haven't tried it but this product shows that collision effects are possible with smoothing: https://www.daz3d.com/ghost-dynamics
Oh, good idea with the smoothing modifier! It won't solve naturally curving around something, but still much better than clipping, thanks for the tip.
That is a remarkably clever bit of software. The results can be quite amazing.
I once did testing on a box with spring shock mounts in it, we had to drop it 3ft (90cm). I did a spring analysis and made a prediction about the rebound. It would bounce into the air, stop, jump higher, stop, fall back halfway to the ground, stop, then fall the rest of the way to the ground, all in about 0.3 seconds. By chance a high speed camera was available during the test, and that's just what we saw. I was chuffed to bits. But I also know how difficult the calcs were behind that analysis... so to generalise the effects and be able to apply it...
I'm in awe of the person who programmed it.

Richard.
That looks great! I snagged this last night, can't wait to play around with it. It's really neat you were able to add it to her hair to make it move like that. So many possibilities!
seems much more controlled than iClone spring
something to wishlist
skirts with bones would work well too
I am used to using spring in iClone and use it on all sorts of things
sadly DAZ studio still lacks physics because it works brilliantly with that
I think you need to add a bone and connect it to the skin, if that is possible in Daz Studio.
Anyone knows if it works on the Mac and DS 4.9?
This looks really fun. I've never done animations, but I'm going to start playing around with it.
Can you explain what the spring dynamics are actually doing in this animation? Are they moving the hair with no direction from you?
It doesn't seem to be working for me. I load a character, give it a geograft tail, load a walking animation, select the first bone of the tail, run the script, and, when I click on "apply effect," it doesn't seem to do anything. I tried rendering the animation, in case the process was so quick I didn't notice it, but the tail is just the usual cylinder parented to a pelvis.
Edit: Never mind, I read here that animate presets should be converted to keyframes so that the script can do anything. I will do further testing.
It operates on studio keyframes, not Aniblocs, so bake to keyframes first (I'm assuming your walk animation is an Anibloc).
Thanks, just realized that :)
From what I can tell it calculates movement/motion (where in the animation the bone is headed along the X, Y, and Z axis) and then applies an opposite movement/motion in the other direction. The strength, speed, and longevity of that opposite motion are parameters that the user can set. At least that's what I THINK it's doing based on the product description and tutorial. :)
I can only say what the iClone and Unreal spring bone modifiers do
I cannot assume this is the same
they act like an inertia swing or translate pivot on the bone in question with movement ignoring any mesh, are bone only
I don't have it, but the video said you could do it with a deformer like they did on the belly of the one example.

That looks awesome! :D
Between this and the face controls I'm actually animating things and it kind of rules? I really want to experiment more with using this on hair and trying node weight maps and dFormers. Last night I made a simple pose transition animation and applied the script to the rigged version of this hair, on the bones of the braid and the bangs. The effects were pretty cool and being able to get bounce effects on hair consistently would be amazing.
thanks for sharing your video and your take on the script, 3Diva.
i'm wondering if it's possible to run a dforce simulation on an animation timeline that's already been spring dynamics'd? or is this one of those either-or situations...you can add spring dynamics to an animation, or you can simulate dforce hair and clothing--but you can't have both.
:)

Good question ... you beat me to it. :)
Yeah, thanks a lot. Now I'll probably have to buy the thing.
I'd think this would be less trouble than dForce for animations.
I used it once on Linday's Long Wet Hair during a pose transition (rising from a kneel to a crouch). I set it up at super low strength and it alternated between draping normally and bouncing back slightly. The final results were a bit fuller than the regular simulation drape. I also tried it with the Classic Long Curly Hair but my computer was absolutely not having it and DS crashed at something like 4% (edit because I just remembered: it ran fine at the same very low strength I used on the wet hair and the results seemed to be slightly more random movement, but it crashed when I tried dialing up the strength a lot). I do want to experiment more with how it interacts with dForce, because I can see this being a bit easier to wrangle for me than wind nodes.
Just in case your question was more general than specifically whether or not you can run a dForce Sim on an item you have already "Sprung", figured I'd throw out that when you run the Spring Dynamic Script with a Node(s) selected, it creates Keyframes at your desired interval to that/those Nodes (and their Children), becoming part of the Animation. Absolutely nothing else about the Scene or Timeline changes, you can select other Nodes and run more Spring Dynamic Scripts, or Simulate dForce along the Timeline exactly the same as you could with whatever Animation you had set up before adding the Spring Dynamic Keyframes.
The part that would be more trial and error as to whether or how well it works, of course, is regarding dForce Sim on something you've already run the Spring Dynamic Script on... I believe it would just have the same general rules as far as the Timeline movements not creating intersections that create explosions/crashes, etc. One nice feature is that the Undo button/Ctrl-Z will undo the Keyframes that the Script added, making it super easy to try it, Undo if you want to try different Settings and the Script as well as Undoing it are super fast.
Totally awesome product! The most fun and exciting thing I've seen or purchased from the store in quite a while. Makes creating one's own completely custom Animations that look somewhat natural much more feesible...
I tried experimenting with deformers on the belly but I get the message "This action requires an item within the scene, with geometry, to be selected" , So could anybody explain how to use a Dformer on a Character so I can try the spring experiment??? Thanks!
I see what I did wrong, will try testing again.
Has anyone gotten it to work with geografts? Still trying with that tail, and now the script writes keyframes when prompted to, but I am not seeing any difference.
Nice! I haven't installed it yet but looking forward to playing around with it. I love to boob action you had going there. :)
If you are applying animation with an AniBlock you need to bake it to the timeline.
Not trolling, but seriously, guys, if you like this, you'd love Blender. And it's gotten to the point where getting your content imported is slightly more challenging that trivial.
Three times now I've watched Daz Studio users lose their fricking minds over functionality that is old news everywhere else, and I am actually as frightened to imagine what would happen if some of you encountered Particle Systems or Drivers, as I am curious to see what those same people would come up with.
Again, not trolling, but it seems like some of you would really enjoy the power that Blender offers and it is worth 10 times the learning curve. Blender and DS complement each other extremely well; one excels at what the other sucks at :)
TheMysteryIsThePoint I think we all know the capablities of Blender but the issue is the learning curve. There are very few tutorials that focus on the actual transition from DAZ to Blender. Primarily how to simply animate the character with out having to spend days or weeks just finding the buttons to push or knowing which mode to be in. If there is a tutorial that breaks down barney style the transferring of assets, getting texture to look right and how to start animating, people trully would be able to lose their minds, I agree.
