dforce hair?

Can dforce be used with hair and if so will we start seeing PA dforce hair products? One area the has always given me problems is getting hair posed properly if the character is in other than the vertical position. Some PA hair products include pose presets and lots of adjustments which althought helpful can still pose problems. I have always hoped for some magical gravity hair where the hair would flow naturaly. Just wondering if dforce will help in this respect.

Technically yes, practically no. So far, but it will presumably get worked on in the future.
Was wondering that myself. It would seem logical to add this ability to dForce. That would definitely be something.
A lot probably depends on the hair. Most transmapped hair is basically a bunch of strips of mesh and a skull cap. If they aren't welded to the skull cap they will all probably fall to the floor. If they are welded it's going to be a whole lot of calculations and a whole lot of collisions to consider.
That whole posing issue is why I tend to only buy short hair. In fact I often use the shorter male hairs on the females because I don't have to worry too much about gravity. I hate trying to get hair to drape convincingly in one area only to find that it is embedded in her body elsewhere.
Me too on th short hair. I like the fibre hair - especially from Redz Studio - but it does slow down the movement of the figure in the viewport considerably.
I thought the problem with hair and dForce was intersecting meshes which cause explosions but then I haven't tried it.
definately don't forget to turn off self collision lol
@divamakeup was able to get some older hairs working with good results (Jaguar Hair was one of them if I recall.) Just like VWD, it's possible, but many of the hairs will crash either simulator. Some of the other older, lower poly hairs may work. I know Sickleyield has a tutorial on using hair with VWD and she had good luck with the "Pure Hair" sets, which were made for Genesis. So far, my hair experiments in both VWD and dForce for hair have been a bust (or rather, explosion!) I even have a hair from Rendo that's made to work with VWD, but the instructions are pretty involved. Haven't had success with that yet either.
The problem is that you really need self collision for it to look right (imo) but intersection and lack of welding will make things go poorly.
Please could anyone who has tried and tested hair that works, please post what does. I really only want to use this for hair..
There are hairs that were made specifically to support VWD, those are probably good prospects for dforce.
Most of the hair I tried ended with strands falling off. I guess you'll have more success with cartoon-stylized hair over realistic ones.
For dForce to work you need to have a single object that is created as a single piece of topology. Now hair is usually created as a scalp that conforms (more or less) to the head and several pieces of cloth like stuff that is the actual hair. These are not "topologically" linked to the scalp.....as a result these will drop of. VWD counteracts this by pinning vertexes of the scalp and the hair. It makes a clever selection (I whish the Blender cloth branch could do that) projecting form the scalp into the hair, thus linking hair and scalp.

How will fibremesh hair react?
I would imagine that for Fibremesh hair, or hair in multiple separate parts generally, you'd need to select the polygon or so at the scalp end and - via weight map or a separate surface - set their dynamic strength to 0.
