Initial Vel (Seed)
The Initial Vel (Seed) module is identical to the Initial Velocity module in that it sets the velocity of a particle when it is emitted; however, this module allows you to specify seed information to be used when choosing distribution values in order to provide a more consistent effect from the module each time the emitter is used. It contains the following member(s):
Random Seed Info
The random seed(s) to use for selecting "random" values for this module's properties.
Get Seed From Instance
If true, the module will attempt to get the seed from the owner instance. If that fails, it will fall back to getting it from the Random Seeds array.
Instance Seed Is Index
If true, the seed value retrieved from the instance will be an index into the Random Seeds array.
The name to expose to the placed instance for setting this seed.
The random seed values to utilize for this module. If multiple values are specified, a value will be chosen at random by the instance.
Reset Seed On Emitter Looping
If true, the seed will be reset each time the emitter loops.
A vector distribution providing the velocity to apply to a particle at its spawn time. The value is retrieved using the EmitterTime of the owner emitter.
Start Velocity Radial
A float distribution providing the velocity to apply to a particle along its radial direction. This direction is determined by the subtracting the location of the emitter from the particle location at spawn time. The value is retrieved using the EmitterTime of the owner emitter.
In World Space
If true, the velocity is assumed to be in world-space.
Apply Owner Scale
If true, the velocity value will be scaled by the ParticleSystemComponent's scale.
