Maya Tutorials:basics of particle

| Comments (12)

If you control particle, you should set up many attributes.
And there are many methed to control particle.
I will explain how to set up particle in a simple way.

maya tutorial particle Three important nodes of particle control
Maya controles particle with tree nodes.
Emitter - the source where particle is generated
Partile - particle itself
Fields - the forces to influence particle

maya tutorial particle Emit prticle from object
maya tutorial particle
Make NURBS or Polygon object and select it,
In Dynamics Menu Set, Particles > Emit From Object

Move the Time Slider, then you will see partciles are generated as above.

maya tutorial particle
Emitter and particle are made, and emitter is the child of the object.

maya tutorial particle
Open the Attribute Editor, selsect emitter tab, change Emitter Type Omni to Surface
Then you will see the particles are uniformly generated from surface.

Rate number where particles are generated in one second
Speed speed of particle
Speed Random  randomness of speed
Tangent Speed the magnitude of the tangent component of emission speed for surface.
The default value is 0. If you enter a value greater than 0, particles are emitted randomly for surface.
Normal Speed the magnitude of the normal component of emission speed for surface.

maya tutorial particle
click the particleShape tab

Max Count number where particles are generated in maximum. -1 is no limit.
Lifespan Mode Live Forever particles don't disappear
  Constant particles disappear
  Random range particles disappear randomly

setting particle attribute(continued)

Particle Render Type 
If you render with Maya Software,you should select the one of tree render type,
Blobby Surface,Cloud or Tube.

render type suitable expression material  
Blobby Surface Drop of water, mud Rambert,Blinn etc  Threshold sets blending of the particles
Cloud smoke, cloud, fog  Particle Cloud  
Tube  fire works, spark, splash Particle Cloud Radius0 - radius of tail、Radius1 - radius of head、Tail - length

maya tutorial particle
If you select the partilce render type, you should click Current Render Type button,
then suitable attributes are displayed.

Setting the Particle Cloud material
If you select the Cloud or Tube render type, you should creat Particle Cloud material with Hypershade
Create > Volumetric Materials > Particle Cloud
and assign it to the particle.

maya tutorial particle
You should connect the Texture Mappings to Life Color, Life Transparency, Life Incandescence.
You should not connect them to Color, Transparency, Incandescence.

maya tutorial particle
In the above, Ramp Texture is connected to Life Color,
and also connected automatically to Color.

maya tutorial particle
In the above, the particles are rendered with Ramp Texture connected.

The Texture is mapped to the time axis
(from the time a particle generated - to the time a particle disappears)
so you should select Constant or Random range
in the Lifespan mode attribute.

maya tutorial particlefields
maya tutorial particle
Select particle
Fields > Field Name
then the particle is cennected to the field,
and is influenced by the field.

If you want to connect another field to the particle,
select the particle again and
Fields > (another)Field Name

The types of fields are below

Air  air,wind 
Drag  friction,brake 
Gravity  gravity 
Newton  gravitation 
Radial  pushes or pulls like a magnet
Turbulance  turbulance 
Uniform  pushes objects in a uniform direction
Vortex  vortex 

maya tutorial particle
The attributes are different according to the fields,
but Magnitude and Attenuation are common.

Magnitude strength of field
Attenuation sets how much the strength of the field diminishes as distance
to the affected object increases.If it is 0, the force remains constant over distance.

maya tutorial particle
Window > Relationship Editors > Dynamic Relationships
The Dynamic Relationships window appears.
If you select particle in the left column, then the connected fields are highlighted.
If you turn off highlighting, it is not connected to the particle.

Your explanation is very nice. I want some more lessons.

Thank you for your visiting my site and your commenting.
I am writing the tutorial of making hair now.
I will add in 2 or 3 day.
Visit again, please.

I will write more.

Your tutorials are great! All of them are wonderful and well thought out.

Please keep it up.

Thank you for your visiting my site and commenting.

nice work

Thank you.

Nice ..........


Thank you.

your explanation is very helpful.I want some more tutorials

Thanks so much for a such a great explanation of particle attributes and fields!

Very nice , but I couldn't figure out how to map the ramp to the time axis. I found no such attribute. Where is it supposed to be?

There is not time axis attribute.
If you connect Ramp Texture to Life Color,
particle color will change with time.
