View and edit the settings you can use to define custom data formats for particles.
Use the Custom Data module to define two additional channels (Custom1
and Custom2
) of data in the Unity Editor for each particle. You can use custom data to specify additional particle properties to control gameplay effects (for example, the health of a player) or particle appearance in a custom shaderA program that runs on the GPU. More info
See in Glossary (for example, the temperature of a surface). For more information, refer to Define custom data formats for particles.
Note: If you want to set your custom data from a script, disable the Custom Data module.
Each channel in the Custom Data module contains the following settings.
Property | Description |
---|---|

X | Defines how the x component of the custom data changes over the particle’s lifetime. This corresponds with the x channel in a Vector4 . For the X component dropdown options, refer to X, Y, Z, and W component dropdown.This property is available only when Mode is Vector and Number of Components is 1 or higher. |
Y | Defines how the y component of the custom data changes over the particle’s lifetime. This corresponds with the y channel in a Vector4 . For the Y component dropdown options, refer to X, Y, Z, and W component dropdown.This property is available only when Mode is Vector and Number of Components is 2 or higher. |
Z | Defines how the z component of the custom data changes over the particle’s lifetime. This corresponds with the z channel in a Vector4 . For the Z component dropdown options, refer to X, Y, Z, and W component dropdown. This property is available only when Mode is Vector and Number of Components is 3 or higher. |
W | Defines how the w component of the custom data changes over the particle’s lifetime. This corresponds with the w channel in a Vector4 .

Color | Defines an HDR color or gradient for the particle. The following options are available:
