When you select a Particle Effect in the Particle Editor, the following properties display.

Click Respawn at any time to view the effect of your changes as you edit the properties of the particle effect system.

Name

Lets you change the default name of the system, which is useful for organization when you have multiple particle effects in your level.

Particle Life

Set Min/Max values to define the particle lifespan (time in seconds).

Total

Set the total number of particles to create for the particle system. This value limits the number of particles allowed to spawn in the system.

Offset

Enter X, Y, Z co-ordinates to control spawn position.

Tilt

Enter a value to control how much tilt when spawned.

Spin

Enter a value to control how much spin when spawned.

Mute

Within the System properties, you can also set the following:

These properties define how many particles to spawn over time.

Set the rate Min/Max values, and use the small graph denoting rate over (particle life) time.

Material

The material map for the billboard.

By default, the billboard uses <particle_effect_name>_default.material that gets created for the effect. (This is a child material of core/stingray_renderer/shaders/particle_default.)

Click the Goto Resource icon, then click Open Shader Graph to edit the shader graph.

Refer to the Stingray Shader Node Reference for details on the nodes added to support the physically based materials for particles, including Output > Particle Base, Particles > Billboard Position, Particles > Billboard Rotation, and Particles > Billboard Size.

Initial Size

Set Min/Max values for the size of the particle.

Scale over time

Adjust the graph to change the size of the particle over its lifetime.

Use system lifetime for scale

Enable to spawn and scale the particle separately from its general attributes

Control height separately

Enable to control the height of the particle.

Initial Height

Set Min/Max values for the height of the particle.

Scale over time

Adjust the graph to change the height of the particle over its lifetime.

Use system lifetime for scale

Enable to spawn and change the height separately from its general attributes.

Luminance

Set Min/Max values to add brightness to the particle.

Gradient

Double-click the white square to change the color of the particle. Click below the Gradient to add white squares and add different colors for the particle.

Opacity over time

Adjust the graph to control the opacity of the particle to achieve a fade in and out effect.

Infinite Life Time (on/off)

Enable for the particles to live infinitely.

Life Time

If Infinite lifetime is not selected, enter a value as the lifetime of the particles spawned.

Use Random Seed

Enable for the particles in the system to be generated randomly.
