(for Daz) pleae check out the short video I am trying to do a simple animation of a girl dropping to the floor just with her hair (to test how to get hair on and working) but as you can see, providing i'm doing it right which I am not sure about, she just collapses on the floor and the hair stays in one place and yes I fitted it to her head before the animation. Please tell me if I am missing out anything before trying the animation with her hair on and also at the end the 2 messages come up... please tell me what those are. Thankyou.

I don't have VWD, but I watched your video and saw a message at the 49 second mark letting you know that there were too many springs generated. Seems like that may be why no simulation was done.

Try checking the Use springs reduction box or the one called Distance min under Use vertices neighborhood. If not enough, increase the min distance value to 1.0 or 2.0.
Also, there are some things you need to do after assigning your hair as such. I would recommend you to watch the basic walkthrough .pdf.
Here are some tips:
1. Build your animation (which you did). Then do your VWD stuff entirely (which you didn't do). VWD stuff is as follows.
2. To get a successful import with no errors for hair (which I recommend importing as cloth), always uncheck the Use Verticies Neighborhood in Dynamic Parameters pane as you import the hair (and check the Use Verticies Extensions). Neighborhood is much more memory intensive and usually only needed with stuff that has parts that fall off during the VWD sim.
3. In forces and springs, lasso (L) select the scalp-ish top of the hair and hit Nail to collision. This will keep the hair in contact with the figure during the animation.
4. In VWD Simulate, hit start dynamic simulation. Sometimes I play with gravity, inertia, etc to get a look I want. When finished, send the animation to host.
5. Now you can run your animation in Daz and the hair object should follow along as it was simmed in VWD.
Final note - a fast animation such as this is MUCH more difficult than a slow or static pose. Will probably take a lot of patience. You can also give it a shot in dForce which has had some success with hair too.
Sorry to reply after so long on this I just gave up out of frustration but am here trying again. I did exactly what Toonces said in the post above but still having problems. I made a quick video showing the process I did from Toonces and some of which is sped up whilst during the waiting parts. I get a bit confused on the 3rd point from what Toonces says above: "In forces and springs, lasso (L) select the scalp-ish top of the hair and hit Nail to collision." This will keep the hair in contact with the figure during the animation." when you say select the slcalpish top of the hair do you mean select it in the Daz tab or VWD tab?!??! and what is meant with the "lasso (L)" part mentioned? please check out the clip and tell me where I went wrong especially I expect on that part. All that seems to happen is the hair just falls to the floor for some reason and doesn't stick to G3F as she moves. All I am trying to do is just have the hair move on her as she does and it seems to be such a chore for me *cries*.
That would be select in the VWD portion and the lasso tool is just the tool you use for selecting. I can't do a screenshot right now as I am rendering. Don't get too frustrated, VWD has a bit of a learning curve to it but once you get the basics down its a great tool.
think you could do that screenshot at some point? :D
I've circled the L, for lasso button, but press L when in that section, and it does the same.
I've also circled Delete all Exchange Files, and Restore Default Parameters; both are useful when you can't get something to work. Just remember to check the box to reduce springs again (not shown in image).
I'm still lost :( so I press L but then what?!??! I just don't get how you supposed to fix the scalp to the top of the head as it still apparently just falls apart when I simulate. Just tell me exactly what to do after pressing the 'L' please. Would show another vid again to show exactly what I am doing upto now on youtube but it doesn't let me for some reason but here's a screenshot...
Have a look at the you tube vids I did; I don't do animations, but they will get you started, although I use a different method in those for fixing hair, which I still use some of the time.
Hmm, step 2.5 should be - click Scene Viewer button. This toggles screen to make the workspaces large enough for you to work with.
The click L.
Then select the verticies. Literally use your mouse to circle (lasso) the hair parts you want to remain in place as seen in screen shot. Every hair is different. Since this particular hair has pigtails and I wasn't sure if they were welded, I went ahead and selected part of each pigtail as well.
Then I clicked on M+ to memorize my selection in case I need to return to it later. Then I clicked on fixed verticies to make them static. I could've done 'nail to collision' but since your latest example was for static posing, I went the easier route. Nail to collision is more processor intensive but needed if doing animation.
You can see the final result in render attached. Looks like wet hair. You can see where the top is a bit poofier because those verts were fixed (not affected by the sim).
If I didn't want the hair to look so wet or if pieces were still falling off, I might import hair as cloth with 'use vert neighborhood' as it does a much better job of welding everything together. However it's much more memory/processor intensive making for a very slow sim and often exceeds memory limits of the program, so I avoid it when possible.
