I have 2 questions about dynamic hair. The first is why do I keep getting a part where the hair groups change like the upper group is flatter that the lower? I started with all the hair settings being the same and I tried increasing the root stiffness but that didn't help.

The other question is why is the hair intersecting the cheek? I have on the do collision for the scene, for the hair group and for the face. Am I missing any? I also checked and the hair was not intersecting the cheek before the simulation was run.

Hi RedPhantom.

Regarding the collision problem,don't know if you already tried this.

In the pose room select the hip of your character. In the properties enable Collision detection and then press the "Apply Collision Setting to Children"

Go back to the hair room and recalculate the dynamics. 

Regards

i had hoped for improvments in SR2 but havent found any, my suggestion would be to turn down dynamics in animations ,with shorter hair such as yours it seems to work pretty well, i would suspect root stiffness falloff is dif on one section than the other making the humps shown, this collision prob i havent seen before ...are you using a hair cap with this? hair looks good cept for those things you mentioned, cute figure...

:O)

I did enable collision on the character.

The root stiffness was the same for this render. I tried changing it but that doesn't help. Yes there is a hair cap.

I don't understand what you mean by turning down the dynamics. I need to figure out what is wrong with this and not just fudge it because this is either going to be for sale or a freebie and I can't very well expect others to use something that doesn't do what it should.

on the parameters tab in the main posing room theres a dynamics dial that can be used to dampen or exagerate  hair animation ... it helps with the overactivity we discussed in a previous post ,the main drawback is  that longer hair has shoulder penetration considerations when turning the head , something that wouldnt be a problem with your shorter hair... after simulation you should find this dial reading 1 turning it down or up even slightly can greatly change how the hair behaves during animation...

i agree that if this is a sale item or even freestuff fudging isnt advisable , but you or others may find this dial usefull when animating short hair, its easily overlooked and i have never seen mention of it in the forums...

:O)

 

If you've applied collision detection to the whole body I can't see how it could be down to missing a part.

It is not clear from the image if this is a problem to do with the collision function not working at all or that collisions are being incorrectly calculated. Are you happy that poser is attempting to apply collisions (i.e. the PC runs slower than a three legged dog in treacle when you run the simulation)? 

 

 

JAFO thanks for the info. Will keep it in mind for my own renders.

 

Ironsoul, I don't see why it is intersecting either. In the clothroom, I'd say there weren't enough vertisies but I have the strands maxed out. As far as the time is concerned, I don't mind, I want the hair to lay correctly. Quality takes time. The hair sticks out something awful if I don't sim it. That is what dynamic hair is all about. Besides like I said this is going to be offered to others. Even if I don't sim it, others will so I need to make sure it is working.
