Child particles that do not track their emitter

This section describes how to make child particles generated from particles that track their emitter so they do not track their own emitter.

Loading sample data

Use CreativeStudio to load the sample data prepared in the following folder. " %NW4C_ROOT%/SampleData/Effect/Intermediate/ManualResource/Star_Particle/Star.cptl "

Confirming the Hierarchical Structure

The hierarchical structure of star.cpt is configured so that particles track their emitter. On the Contents panel, check that star_ParticleEmitter emitter is displayed under the start_ParticleModel hierarchy. For settings to make particles track their emitter, see Particle Tracking Settings.

Making Tracking and Non-tracking Settings Using Positions in the World Coordinate System

This section gives the procedure for making and confirming tracking settings for child particles.

(1) Select Star_Child_Particle on the Contents panel and unselect Place in world coordinate system on the Properties panel.

(2)Select Star_Model and check particle motion while moving the slider for the Translate Y value on the Properties panel.

(3) Child particles track the motion of the model.

This section gives the procedure for making and confirming non-tracking settings for child particles.

(4) Select Star_Child_Particle on the Contents panel and re-select Place in world coordinate system on the Properties panel.

(5) Select Star_Model and check particle motion while moving the slider for the Translate Y value on the Properties panel.

(6) Child particles are let go from the model.

For details on the hierarchical structure of particle effects, see Structure-Dependent Differences and Characteristics in the User's Guide.
