    I was just wondering the answer to that question, thank Richard and Google cheeky (about sharing a dforce weight map for older hairs...)  Seems there would be a good freebie market for that!

    I think people would love to have the older hairs dForce compatible and weight mapped. I'm hoping to do a few weight maps to share, I just need to find the time. :)

    I don't see a reason to not share them if they're easy to share.   I mean, if I'm doing it anyway, why not make it available? 

  • What am I doing wrong? The example is Brinwyn hair, but the same happens with any hair I try. The simulation always takes off towards the camera and towards the right. I experimented with weight maps, stabilisation time, gravity, air density and excluded the skull cap from the simulation. Always the same result. What can I do??

    Check if self collision is enabled: if so, disable it.

    You also might need a morph to separate the mesh parts, if that doesn't work. Self collision helps it look more authentic as it doesn't pass through itself but can at times (or so it seems to me) get the mesh into a game of chase - or maybe follow the leader.

    Came across this video on how to do this as well..

    The biggest problem I've run into is that for whatever reason the hair likes to...bounce back up? If that's the correct description. Like it will start falling down, but then it will bounce back up half-way through the timeline and it will never completely fall. I'll paint the weight map so the crown looks great, and then I'll find a morph that spreads the hair out so I can let it fall naturally during the sim. But it just doesn't want to unless I turn dynamic strength all the way up...which results in the heavy, wet-looking hair. So far I haven't found a happy medium...I either have hair that bounces back up, or it ends up looking wet.

    Hi, I'm wondering if anyone might have any insight on what I can do to make this work. I have watched every video on weight mapping I could find on youtube and I just can't figure out what I'm doing wrong. As you can see, I made the whole head grey (I first just tried doing the hairline but that didn't work either). It just keeps falling forward on her. I even tried the dForce master thing from EchV0 after weight mapping with the exact same result. Knowing me, it's probably something super simple that I'm overlooking somehow. Any thoughts on what I could do to make this work would be greatly appreciated!

    Disable self-collision, to see if that is causing you issue.

    If it is, reduce the collision distance; I often reduce it to .1; i have gone lower, but avoid if possible, but try to only reduce as much as needed to get it to work.

    I ran to do some errands, I'm excited to give this a try when I get home and see if it works. Thank you for the suggestion!
