# TP Surface Emitter

Back to reference Back to index
The Surface Emitter preset will emitt particles along the normal of the surface at the point of emission.
It works with all polygon objects.
On: Activates the Emitter. This parameter can be easily animated to switch the emitter on and off as needed
Particle Group: Thinking Particles group to which the generated particles will belong
Shape: Object that is used as a shape for the particle
Polygon Surface: Polygon object from which surface particles will be emitted
Source:

Polygon: Particles will be emitted from polygon surface
Point: Particles will be emitted from vertices
Edge: Particles will be emitted along edges

Selection: Particle emission will be restricted to the assigned selection when used.
Type:

Count will emitt as many particles as neccesary to keep the over all count at the set number of particles
Rate will emitt the set number of particles per second
Shot will emitt the set number of particles per frame

Particle Number: Number of particles emitted
Speed: Speed of emitted particles in units per second
Speed Variation: Variation of the speed of emitted particles, the resulting speed will not go above the set speed
Life: Lifetime of particles in frames
Life Variation: Variation of particle lifetime, the resulting lifetime will not exceed the set lifetime
Align: If true particles will be aligned in direction of movement during emission
