TP Follow Hair 
TP Follow Hair will guide particles along the dynamic guides of a HAIR Object.
Hair Dynamics need to be active to make the preset work.
On: Activates the preset. This parameter can be easily animated and can be switched on and off as needed.
Particle Group: Thinking Particles group that will be used.
HAIR Object: HAIR Object that will be used.
Factor: Defines how strongly the particles will follow the hair.
Friction: Force to slow the particles while following the hair.
Radius: Distance between Hair and Particle that determines whether or not the preset will be made active.
TP Hair Collider
TP Hair Collider allows collisions between Hair Guides and particles. The influence they have on each other can be defined separately.
Hair Dynamics need to be enabled for the preset to work.
On: Activates the preset. This parameter can be easily animated and can be switched on and off as needed.
HAIR Object: HAIR Object that is taken into account for the collisons.
Particle Group: Thinking Particles group that will be used.
Particle Factor: This parameter defines how strongly the particles will be influenced by the hair. 0% = no effect, 100% will result in the movement of the hair being transferred completely to the particles.
Hair Factor: This parameter defines how strongly the guides will be influenced by the particles. 0% = no effect, 100% will result in the movement of the particles being transferred completely to the guides.
EPS: Epsilon environment. The radius around particles that will be used to detect collisions with hair strands.
TP Hair Tip Emitter
The Hair Tip Emitter preset emits particles along the tangent of the hair at the tips of guides.
Using hairs instead of guides isn't possible with this setup.
Hair Dynamics needs to be enabledfor this preset to work.
On: Activates the emitter. This parameter can be easily animated and can be switched on and off as needed.
Particle Group: Thinking Particles group to which the generated particles will belong.
HAIR Object: HAIR Object where the tips should be used to emit particles.
Shape: Object that is used as a reference for the particles' shape.
Type:
- Count will emit as many particles as neccesary to maintain the overall number of defined particles.
- Rate will emit the defined number of particles per second.
- Shot will emit the defined number of particles per frame.
Particle Number: Number of particles emitted.
Inherit Velocity: When enabled, the particles will start with the velocity of the moving tip; the speed parameter will then be ignored.
Guide Selection: The emission will be restricted to this selection of guides if the parameter is used.
Speed: Speed of emitted particles in units per second.
Speed Variation: Variation of the speed of emitted particles. The resulting speed will not exceed the speed defined.
Life: Lifetime of particles.
Life Variation: Variation of particle lifetime. The resulting lifetime will not exceed the lifetime defined.
Spread Angle: Opening angle of the emitter conus.
Align: If true, particles will be aligned in direction of movement during emission.
TP Stick to Hair
TP Stick to Hair will make particles stick to dynamic HAIR Guides when they come within a defined distance of the guide. They will become unstuck once the point on the guide to which they are stuck moves faster then a velocity defined.
Hair Dynamics needs to be enabled for this preset towork.
On: Activates the preset. This parameter can be easily animated and can be switched on and off as needed.
Particle Group: Particle group of freely-moving particles.
Sticky Group: Particle group to which particles that should become stuck will be assigned.
HAIR Object: HAIR Object to whose dynamic guides the particles should stick.
Detection Radius: Radius around every particle that defines if it is close enough to a guide in order to become stuck to it.
Unstick Velocity: If a particle that is stuck to a point on a guide exceeds this velocity it will become unstuck.
