Hair vertex maps

Hey all, I’m working to fine tune my hair dynamics.
I have a Chester Cheetah character and I want the dynamics to only effect certain areas.
When dynamics are applied to the shorter, snout fur, it’s looking busy and odd.

What I’ve done… I created a hair vertex map using the comb on the guides and applied that map to drag, rest hold, etc.
But I can’t get the snout fur to stay completely still. Any suggestions?

Hi Lincoln,

Images can’t tell me a lot. I need a scene file.
I understand that you might not like to share this file in public. If that is correct, I can provide an upload link.

However, even if I really think that guessing is not professional, here we go:
In Hair> Dynamics> Have you set the Dynamics to Riged? Does it help?
Example:

Values are extreme to show the effect.

All the best

Dr. Sassi,
It looks like that tutorial you linked is going to do the trick. I just got onto Cineversity yesterday and this is the tutorial I’ve been looking for. I did have the rigidity on but the secret seems to have been in just putting the vertex map on the rest hold. As soon as I finish with this current job that is rendering, I will retry. Thank you very much for the help and direction!

Hi Lincoln,

Thanks for the reply. Sounds great. Please keep in mind that the dynamic state you like is best set as
Main Menu> Simulate> Hair Edit> Set Initial State.

This will be the point where the Rigid might come in handy.

The Rest Hold is this using this initial state.

The Vertex maps will work as a factor, and the settings done above (Properties) the Vertex fields will be defined (per guide) by those Vertex values.

The Spline interface below those fields gives even more options (Modifiers), but as the numbers above, they work globally on that hair Object.

I think Patrick pointed to all these areas, but I wanted to make sure that the connection among all elements is clear. (Since I write in a forum, I have to overshare a little bit. I hope you don’t mind.

ENJOY.
