simple gen

 

 

This is a simple particle generator that will generate particles at 0,0,0 coordinates. To place particles on the object surface, use location object node along with the set part attribute node.

 

Note: Particle generator output pins and data are available only when the particle is created. To access particles continuously, use the get particle group node.

 

 

[Inputs]

 

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 the same unique cluster group.
• Object - Particles are assigned to the same unique cluster group based on the object they are created on.
• Particle - Each particle is assigned to its own unique cluster group.

 

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

 

Time Start - Emission start time. There will be no emission before this frame.

 

Time End - Emission end time. There will be no emission after this frame.

 

 

Properties

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 - 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.

 

AutoSeed - Using this option will make each Spline Gen node generate different patterns even if the seed number is the same.

 

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.
