Creating a dForce chain?

SnowSultan

Could someone give some recommendations on how to create a simple dForce chain or cord that will drape properly over a hand or other object? I don't remember seeing any in the store, which leads me to believe it can be done with a primitive (maybe a long, very thin cylinder?). Thanks in advance for any advice.

Dforce would need to be able to do rigid body physics I think? It might be possible with the dynamic surface add on, tho I'm not sure how well the chains would retain their shape.

Oh it could be more simple than that, when I said 'chain', I really meant anything that could pass for a necklace, bracelet, or whatever. Even something like a clothesline, I'm basically just trying to find out how to make a dynamic cord without it exploding or otherwise freaking out.

SY dForce Ropes, Vines and Tubes might not be what you're looking for but it works well from the limited testing I've done. Maybe it could help you figure out how the dForce add-ons work to hold the shame while draping.

Oh there is this here.

cords are relatively simple theres a few things in the store. For instance:

I think it was free at one point? so you might have it

Its probably something that one could do with a cylinder provided one gives it a reasonable amount of geometry and fiddle with settings so it doesn't just collapse on itself.

 

I also  just tried a proper chain with the settings borrowed from afformentioned string light set expecting it to explode in a fiery ball and...

 

It worked surprisingly well? for a chain you will want each link as low poly as possible the image I uploaded has subd applied

Thanks for all the suggestions, I will wishlist the DAZ products mentioned (I don't buy at Rendo unless absolutely necessary, too much variance in quality and no refunds).

Jcade: Yeah I might have those string lights, I will take a look at them and see. Thanks.

Wow, I wonder how SWT did it?  I've been trying to make solid-geometry dForce chains since day 1, and the links always fall apart on sim for me.  The closest I ever got was this:

In this case, each "chain" is two very long 2d planes at right angles to one another to create a primitive "3d" look.  This allowed them to both be rigged and be a physically continuous geometry, the only way I personally ever got that to work.  In the case of the vines, tubes, ropes set, all of those are some variation on a long cylinder, rigged with bones and stiffened with dForce Dynamic Surface Add-Ons.  A Dynamic Surface Add-on is like, you have to start from the actual geometry you want to stiffen, then delete enough of it to create "ribs" inside the cylinder and extrude them inwards.  There has to be a 100% overlap between some part of the Surface Add-On and the original item or it fails in my testing, but it does work for making things look a bit more solid.

Just a hunch, but since the chains come in pre-determined lengths, and we can't just add or remove links, maybe there is some invisible geometry keeping the links together. Then it would be that invisible geometry which gets weightmapped for dForce, while the visible links get mapped as (nearly) rigid. dForce wouldn't be the thing keeping the links together, the invisible geometry does that. This could also explain why the chains don't swing back and forth after falling, each dForce connection piece stops swinging because the pieces above and below it (the visible chain links) are rigid.

This is a dForce chain I've made. I've been meaning to write it up for my dForce thread for some time, will have to add that to my to do list.
