– Amount let you decide the angular velocity.
– The bigger this value the greater the particle’s angular velocity.
– In these examples some particles (represented as Suzanne) rotate around the Global X and Global Z axis. See how two different values of Amount affect the simulation.
– These settings control how the POINTS OF EMISSION of the particles are distributed throughout the emission locations.
– Three different types of distribution for your particle system: Jittered, Random and Grig.
– Jittered: Particles are placed at jittered intervals on the emitter elements (you can notice some regularity in the distribution of emission points):
– Random: Particles are emitted from random locations in the emitter’s elements.
– When applied to Faces particles born randomly on all faces.
– When applied to volume particles born randomly in the entire volume (so some particles may born on its faces).
– Grid: Particles are set in a 3D grid and particles near/in the elements are kept:
– In this video you can see a Grid Distribution for a single face and for a two faces mesh.
– In the next video you can see a Grid Distribution for Volume. Note how some particles lie out of the mesh. I think this should will be fixed…
Random Even Ditribution
– Additional option for Random and Jittered Distribution.
– When enabling this check box, the number of emitted particles is based the volumes size (i.e. the bigger the volume the more the number of particles).
– When disabling this check box each volume will contain the same number of particles.
Distribution Random
Distribution Jittered
– This parameter is common to Newtonian, Keyed and Boids sections.
– Enabling this option a larger (inertial) mass is given to larger particles.
– In this example, a wind force field is influencing the path of the particles. The particles with a smaller (inertial) mass are deflected more
– This parameter is common to Newtonian, Keyed and Boids sections.
– Mass: simply the particle mass.
– In this example a wind force field (the grey sphere) is influencing the path of the falling particles. The bigger the (inertial) mass the less the deflection. If someone is asking himself why I did not use two bodies of different mass falling remember: bodies of different masses fall at the same rate in absence of other forces!
– The menu let you to decide the rotation axis (Global X, Global Y, Global Z, Velocity, Horizontal, Vertical, Random and None)
– In this example some particles (Suzanne) are rotating around the Global X and Global Z axis:
– Randomize Phase gives an amount of random to initial phase as set in Phase.
– The larger the value of Randomize Phase the larger the variation.
– Remember: this value affects ONLY the INITIAL phases!
– In this example you can see variations in initial phase for values from 0.0 to 2.0
