The spawn stage of the particle simulation. Modify Attribute nodes added to this container are processed for a single frame the moment the particle is created.
This node contains several options for defining the VFX system such as the spawn rate, spawn mode, and attribute bounds.
A note about precision: Under Advanced Options, it is possible to set the minimum and maximum values for several attributes. The difference between the minimum and maximum values has an effect on the attribute’s precision: larger bounds become less accurate, and smaller bounds become more accurate. An attribute is always clamped to its minimum and maximum values set here. Safe values are chosen by default, but you are free to edit them as necessary. For example, if you have a very small, slow moving particle system, you might want to lower the position and velocity bounds to gain more precision.
|Spawn Space||dropdown||Selects whether or not particle attributes are affected by the VFX Component’s SceneObject transform. When set to Local, particle position, rotation, and scale are transformed by its Scene Object. When set to World, the Scene Object’s transforms are ignored.|
|Spawn Mode||dropdown||How particles are spawned over time. Continuous spawns particles at a rate defined by Spawn Rate (per second). Burst will instantaneously spawn particles at a rate defined by Burst Rate (per second).|
|Burst Rate ( per sec )||float||When Spawn Mode is set to Burst, this controls the frequency that particles are spawned. A value of 1 means particles are spawned every 1 second, a value of 0.5 means they are spawned every 2 seconds, etc.|
|Spawn Rate ( per sec )||float||When Spawn Mode is set to Continuous, this controls how many particles are spawned every second. When Spawn Mode is set to Burst, controls how many particles are spawned at every burst tick.|
|Max Particle Life ( secs )||float||The maximum amount of time particles are allowed to live.|
|Max Particles||int||The total number of particles in the system. When Spawn Mode is set to Continuous, this value is a product of SpawnRate * MaxParticleLife. When set to Burst, this value is a product of SpawnRate * MaxParticleLife * BurstRate.|
|Advanced Options||bool||Shows Advanced Options|
