CINEMA 4D R11 Quickstart – HAIR
Set Length to 21 and Segments to 6. The Segments setting defines the number of individual segments each
guide is made up of (this only influences how guides are displayed in the editor, not the rendered hair). If
Segments were to be set to 1 each guide would consist of only a single segment and gravity could not bend
the guide. Our guides have 6 segments, which means they can be bent at 5 points along their length (see the
Tips & Tricks chapter for further details concerning guide segments).
Now switch to the Forces tab and activate the Surface to Hair setting. This will prevent the hair tips from
penetrating any surfaces when gravity is applied (collision detection). If we were to apply gravity at this point,
though, the hair tips would still penetrate the polygon mesh since we have not yet told the polygon mesh that
it should interact with the hair.
To do so, click on the Bear_mesh object in the Object Manager and assign to it a Collision tag (right click: Hair
Tags / Hair Collider.
If you play the animation now you will see how the hair is pulled down by the gravity.
Stop the animation before it reaches frame 100 to prevent the calculation from starting anew. Alternately
you can start the Dynamics calculation in the HAIR object by pressing the Relax button in the Dynamics tab’s
Animation menu. Click this button after the animation has been set to frame 100).
In order not to lose this state we have to tell HAIR that this should be our new initial state. Simply setting the
animation back to frame 0 will set the calculation back to its original state and Hairbert would again look like
a porcupine in shock.
