Note: This class is not available in Autodesk VIZ.
The width of the emitter icon.
The width of the emitter icon.
When on, hides the emitter in viewports. When off, the emitter is displayed in viewports. The emitter is never rendered.
Set the display icon for particles in the viewport:
0- Dots (Displays the particles as dots.)
1- Ticks (Displays the particles as crosses.)
2- Mesh (Displays the particles as mesh objects. This results in slower viewport redraws.)
3- Bbox (For instanced geometry only, this displays each instanced particle, whether a single object, a hierarchy, or a group, as a bounding box.)
Sets the percentage of particles displayed in the viewport.
Set the method by which the number of particles is determined over time:
0- Use Rate (Specifies a fixed number of particles emitted per frame.)
1- Use Total (Specifies a total number of particles formed over the life of the system.)
Tip: Generally, Use Rate is best for a continuous flow of particles, like a trail of pixie dust, while Use Total is better for bursts of particles over a short period of time.
The number of particles emitted per frame.
The total number of particles to be emitted.
The velocity of the particle at birth, along the normal, in units traveled per frame.
Percentage of variation to the speed of emission for each particle.
Amount of random rotation of the particles.
Speed at which the particles rotate.
The frame at which particles begin to exist in the scene.
The last frame at which particles are emitted.
Time at which all particles will disappear, regardless of other settings.
The lifespan of each particle from the time of creation.
The number of frames by which the life of each particle can vary from the norm.
When on, enables the addition of a time offset to the equations of motion that prevents puffing in time.
If the object-based emitter is moving in space, particles are created at integral times at positions along the geometry's path between renderable positions. This prevents puffing in space.
If the emitter is rotating, turn this on to avoid puffing and produce smooth spiral effects.
The target size for all particles in the system.
The percentage by which the size of each particle may vary from the norm.
The number of intervals over which the particle grows from being very small (0.1a system constant) to the Size value.
The number of intervals over which the particle will shrink to 1/10th its Size setting prior to its death.
By changing the Seed value, you achieve different results using otherwise identical particle settings.
The type of particle emitted:
0- Standard Particle (Uses one of several standard particle types, such as triangle, cube, tetra, and so on.)
1- MetaParticles (Uses Metaball particles. These are particle systems in which the individual particles blend together in blobs or streams.)
2- Instanced Geometry (Generates particles that are instances of either an object, a linked hierarchy of objects, or a group.)
standardParticle = 0 - Triangle; 1 - Cube; 2 - Special; 3 - Facing; 4 - Constant; 5 - Tetra; 6 - SixPoint; 7 - Sphere
Determines the tightness of the particles, with regard to their tendency to blend with other particles. The higher the Tension, the harder the blobs, and the harder it is for them to merge.
The percent of variation of the Tension effect.
The coarseness for metaparticles in the rendered scene.
The coarseness for the viewport display.
When this is on, the rendering coarseness is automatically set, based on the size of the particles, and the viewport coarseness is set to about twice that of the rendering coarseness.
Turns on/off One Connected Blob.
The object which is instanced.
Turn this on when you want to include the linked children of the picked object in the particle. If the picked object is a group, all children of the group are included.
Set the animation offset keying:
0- None (Each particle duplicates the timing of the original object. As a result, the animation of all particles will be identically timed.)
1- Birth (The firstborn particle is an instance of the current animation of the source object at the moment of that particle's birth. Each subsequent particle then use the same start time for the animation.)
2- Random (This option is the same as None when Frame Offset is set to 0. Otherwise, each particle is born using the same animation as the source object at the time of birth, but with a random offset of frames, based on the .instanceFrameOffset value.)
The property value is the UI value times the number of ticks per frame. The number of ticks per frame is accessible via the ticksPerFrame system global variable.
Specifies how a mapped material affects the particles:
0- Time (Maps particles over time.)
1- Distance (Maps particles over a distance.)
2- Emitter Fit Planar (Maps particles at birth, based on their point of emission from the rectangular Blizzard emitter icon. The UV range of the mapped material runs from 0 to 1 over the width and length of the emitter.)
The number of frames from the birth of the particle that it takes to complete one mapping of the particle.
The distance, in units, from the birth of the particle that it takes to complete one mapping of the particle.
Updates the material carried by the particle system, using the source specified:
0- Icon (The particles use the material currently assigned to the particle system icon.)
1- Instanced Geometry (The particles use the material assigned to the instanced geometry.)
The number of frames for one rotation of a particle. If set to 0, no rotation takes place.
The percent of variation of the Spin Time.
The initial particle rotation, in degrees.
The percent of variation of the Phase.
The spin axis for the particles:
0- Random (The spin axis for each of the particles is random.)
1- User Defined (Uses a vector defined in the three X, Y, and Z spin vector values.)
Spin vector of the X-axis.
Spin vector of the Y-axis.
Spin vector of the Z-axis.
The amount, in degrees, by which the spin axis of each particle may vary from the specified X Axis, Y Axis, and Z Axis settings.
Turn on/off interparticle collisions:
The number of intervals per rendering interval, during which an inter-particle collision test is conducted. The higher the value, the more accurate the simulation, but the slower the simulation will run.
The degree to which speed is recovered after a collision.
The percentage of random variation of the Bounce value, applied to the particles.
The percent of particles that inherit the motion of the object-based emitter at the moment of particle formation.
Modifies the amount by which the emitter motion affects the particle motion. This can be a positive or negative number.
Percentage of variation of the Multiplier value.
Determines what happens to particles at either collision or death:
0- None (Particles act as they normally would. That is, upon collision, they either bounce or stick, depending on Particle Bounce settings in the deflector, and on death they disappear.)
1- Die After Collision (Particles disappear when they strike a deflector to which they're bound, such as the SDeflector.)
2- Spawn on Collision (Spawn effects take place upon collision with a bound deflector.)
3- Spawn on Death (Spawn effects take place at the end of each particle's life.)
4- Spawn Trails (Particles are spawned from existing particles at each frame of that particle's life.)
The life, in frames, that the particle will persist after the collision. Setting this to 0 (the default) causes particles to vanish immediately after the collision.
Varies the Persist value of each particle, when Persist is greater than 0. This lets you "feather" the dying off of the particle density.
The percentage of particles that will spawn. Reducing this reduces the number of particles that produce spawned particles.
Percentage range by which the Multiplier value will vary, frame by frame.
The amount by which the direction of the spawned particle can vary from the direction of the parent particle. A setting of 0 means no variance. A setting of 100 causes the spawned particle to travel in any random direction. A setting of 50 causes the spawned particle to deviate from its parent's path by up to 90 degrees.
The range of a percentage of change in the speed of the spawned particle relative to its parent. A value of 0 means no change.
Sets the type of speed applied to spawn particles:
0- Slow (Applies the .spawn_Speed_Chaos value randomly to slow the speed of the spawned particles.)
1- Fast (Randomly speeds up particles based on the .spawn_Speed_Chaos value.)
2- Both (Some particles speed up, while others slow down, based on the .spawn_Speed_Chaos value.)
When on, spawned particles inherit the speed of their parents, in addition to the effect of the .spawn_Speed_Chaos value.
When on, uses the .spawn_Speed_Chaos value as a set value, rather than as a range applied randomly to each particle.
lifespanValueQueue is an array of integers which correspond to lifespan values for each spawned generation of particles.
objectMutationQueue is an array of nodes which correspond to instanced-object particle types. Each generation of spawning will use the next node as its object type.
