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.





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.




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.





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.
