spawn gen

 

 

This generator will create particle as location of another particle or custom location.

 

 

[Inputs]

 

#Particle Stream - This pin requires a particle stream to be connected.

 

#Position - If this pin is connected then this position will be used as a point of new particle spawn.

 

#Pass1 - This pin allows you to pass through values directly to the Pass1 output pin.

 

#Pass2 - This pin allows you to pass through values directly to the Pass2 output pin.

 

Enabled - Enable or disable node evaluation.

 

Particle Group - Generated particles will belong to this this group.

 

Cluster By - Each particle is automatically assigned to a cluster. There are several options how you can group particles into clusters.

• Constant - All particles that this node creates are assigned to the same unique cluster group.
• Simulation Frame - Only particles that are created on the same frame are assigned to th same unique cluster group.
• Inherit From Particle - Cluster group will be inherited from the input particle.
• Particle - Each particle is assigned to its own unique cluster group.
• Trail/Segment ??? This mode can be used with Segment spawn type to assign the same cluster to the entire segment.

 

Delete Parent - As soon as particle has been spawned, a parent particle will be deleted.

 

Spawn Type - There are few options how particles will be spawned.

• Per Call -.Each time this node is called it will spawn particles.
• Per Frame - Particles will be generated on a frame basis as defined by the Birth Rate.
• Travel Distance - Particles will be generated when they reach user defined travel distance. Once generated, the distance will be reset and the cycle will repeat.
• Segment - Particles will be generated on a segment as defined by two points ??? input particle position and position defined through the Position pin.

 

Birth Rate - Number of particles that will be generated at each frame.

 

Quantity - Number of particles that will be created.

 

 

Location

Mode - Defines where particles are spawned.

• Position - Particles are generated at the parent particle???s position. If the Position input pin is connected, its value overrides the parent particle position.
• Parent Shape - Particles are generated across the faces of the parent particle???s shape.

 

Use Selected Faces - Limits particle generation to the parent shape???s selected faces only.

 

Use Material ID - Limits particle generation to faces of the parent shape that use a specified Material ID.

 

Material ID - Specifies the parent shape Material ID on which particles will be generated.

 

Position Jitter - Particle position will be jittered around the input position.

 

#Jitter Dir - This option is visible only as an input pin. When connected, it allows user to define a direction along which jittering is going to occur.

 

Jitter Var Min - Visible only when Jitter Dir input pin is connected. It allows user to define a minimum angle along the Jitter Dir where new particle will be created.

 

Jitter Var Max - Visible only when Jitter Dir input pin is connected. It allows user to define a maximum angle along the Jitter Dir where new particle will be created.

 

 

Properties

Birth Age - Spawned particle`s initial age.

 

Life Span - Particle life span in frames. Particles that are older than its lifespan will be automatically deleted.

 

Life Span Var % - Life Span variation.

 

Speed units/s - Particle speed in current 3ds max units per second.

 

Speed Var % - Particle speed variation.

 

Direction - Particle initial travel direction.

 

Direction Var Min - Minimum direction variation angle in degrees.

 

Direction Var Max - Maximum  direction variation angle in degrees.

 

Size - Particle size.

 

Size Var - Particle size variation.

 

Density - Particle density. Particle mass is computed from particle size and density so that bigger particles will have bigger mass.

 

Density Var % - Density variation.

 

Color - Set particle color.

 

Seed - Random number generator seed. Change this value to get different pattern.

 

 

[Outputs]

 

Particle Stream - Generated particle stream.

 

Particle # - Generated particle index. It goes from to Total#-1.

 

Total # - Total number of particles that will be generated at current frame.

 

#Pass1 - Value from the Pass1 input pin.

 

#Pass2 - Value from the Pass2 input pin.
