Hair issues

[LucentDreams]

is it always going through the hand or is this at certain points of the animation

If its always goign through the hand it seems like you may need to make your model a little larger. Despite ciema's hair system being a really powerful system it has one notable flaw with small objects in that the interpolation between guides maybe interpolate hair through instead of around. the easy way to work aroudn this is have more guides on the outside of the mesh. I've not encountered it on a hand before but on animal ears its been problematic for sure since the ears are so skinny



I have a guess though that your animating without dynamics is the real issue here, so that would depend on if it only happens at certain parts of the animation. Something not covered in the manual, is that when you are animating without dynamics, the first frame of your animation is the one used to dictate how the hairs will interpolate for the rest of the animation. So always make sure the very first frame is a neutral pose without limbs too close together. When dynamics is on its not as much of an issue as the hairs move around, but without dynamics, the hairs stick to their relation to the surface normal, so guides often will spread wide apart leaving balding or sparse patches or even intersecting hair.

Kai your awesome, I done everything I could to fix this I never thought for a second that the guides would effect this. I upped them and then re grew them and it fixed it. Do the number of segments also effect this? Or are they mainly for styling?

Can you also tell me at what scale this problem can occur, I don't really understand how scale works in cinema?

Thanks again

oh just that guides interpolotate with a certain proximity, if guides are closr to the guies on the opposite side of the mesh then with other guides on the same side then it interpolates inside the mesh, this happens more often when models are tiny within cinemas space. So small things like fingers ears are areas where this will often happen.
