jmart714 Posted November 2, 2007 Share Posted November 2, 2007 Hey guys, So, I've been trying to figure out how to stop hair from passing through my characters face. I've read a post that said, turn on object collisions in dynamics. I did this, but it only keeps the hair from passing through the scalp. I changed the collision radius, but the higher number I go, the hair becomes a crazy mess. It looks like my character is under water. Thanks.

John Bigboote Posted November 2, 2007 Share Posted November 2, 2007 THIS is something I have been struggling with as well. Can't get it to work. The longer the hair the worse C-D gets. There are a couple of things to experiment with: 1- Maybe a denser geometry will catch the collision detection better? 2- Maybe make the face geometry UNattached to the geometry with the hair emitters? 3- Maybe give the hair more (or less?) control points...max is 25. 4- There HAS to something to the 'Bounce and Friction' levels...one high the other low...both high...both low... ???? 5- Maybe make invisible 'shields' that contain the hair? The only thing definate thing I would say would be to set the angle limit low so the hair can't get too close to the face... Unfortunately, I haven't had too much success with the above. I think my expectations are too high, because when I think of collision-detection I think of hair that simply WILL NOT pass thru geometry, kinda like in real life. I've made some tests where I make a simple ball with long hair and run various objects by it or run it over various objects and the C-D seems to work fine. But once I put long hair on a rigged animated character all bets are off. And I've probably done HUNDREDS of tests. I haven't pestered the hash programmmers with this because I'm sure they know it's a limited feature, and other than that Hash-Hair is FANTASTIC! Also, I'm sure that to get it working right is a monstrous programming challenge requiring many-many-many hours/weeks/months. I've also tinkered with the possibility of using thin strips of SimCloth as hair, because SimCloth's Collision-Detection seems to be a little more successful... Good luck and PLEASE share the knowledge you gleam...especially if you find success! Quote Link to comment Share on other sites More sharing options...
jmart714 Posted November 3, 2007 Author Share Posted November 3, 2007 Thanks, I'll keep messing with it. I'll definitely chime in if I figure anything out. I wasn't even going to do hair, but I liked how cool it looks. I really hope there's a way. Justin Quote Link to comment Share on other sites More sharing options...
