## Split operator

The Split operator tests if particles satisfy conditions based on how they entered the event.

#### Test TRUE for

##### Percentage of new particles

A percentage of new particles in the event will satisfy the test condition.

• Percentage %: the percentage value to use.
##### Random Chance

Particles will satisfy the test condition based on a random probability.

• Probability %: the probability value to use.
##### Per frame

A random amount of particles will satisfy the test condition per frame

• Amount: the amount to send out per frame.
##### Every Nth particle

Every Nth particle that enters the event will satisfy the test condition.

• N value: the N value to use.
##### First N Particles

The first Nth particles that enter the event will satisfy the test condition.

• N value: the N value to use.
##### Particle after first N

Particles after the first Nth particles that enter the event will satisfy the test condition.

• N value: the N value to use.
##### Particle after random N

Particles after the random N particles in the event will satisfy the test condition.

• N value: the N value to use.
##### New particles before

Only new particles that enter the event before a certain frame will satisfy the test condition.

• Frame: the frame value to use.
##### New particles after

Only new particles that enter the event after a certain frame will satisfy the test condition.

• Frame: the frame value to use.

#### Split metric

• Event index: the event index of the particle will be used when considering various split conditions (ex: “Every Nth particle: 2” = (eventIndex % 2) == 0).

• Birth ID: the birth ID of the particle will be used when considering various split conditions (ex: “Every Nth particle: 2” = ((birthID % 2) == 0).

#### Uniqueness

• Seed: the seed value for all varied parameters.
