Under Alpha, you can set the alpha of a particle color.
This page describes Alpha settings and features.
A | Animation | Sets whether there is an alpha animation. Settings shown under Alpha change when creating an animation. |
---|---|---|
B | Default | Sets the standard value of alpha using a value from 0 to 1. Enable (checkbox) can be used to enable/disable settings. |
C | Runtime Setting | To read about the Enable checkbox and resource copying, see here. |
Note: The default setting is Do not animate.
The settings shown change when creating an animation.
You can select whether to animate the particle alpha from a pull-down menu.
The following three items can be selected when setting an alpha animation.
Item | Description |
---|---|
Do not animate | Alpha animation is not performed. |
Overwrite previous value | Select this when you want to animate using a curve. |
Overwrite previous value using four-key method | Use this to create low-load animation comprised of key information for only four locations. |
Alpha animation is not performed.
Select this option when setting the default value for the alpha or when creating an animation using a curve.
Curves can be created using the CurveEditor panel.
This setting specifies the particle alpha default value from 0 to 1.
Playback Options are options to configure playback of an animation created in the CurveEditor panel along the specified timeline.
Options | Description |
---|---|
None. | Do not use playback options. |
Fit to Lifetime | Fit to lifespan is a playback option that automatically links animations created on the CurveEditor panel with particle lifetimes. |
Specify Frame Count | Specify frame count is a playback option that loops animations created in the CurveEditor panel based on the specified frames. |
Frames per Cycle | This specifies the number of frames in a single loop cycle when looping animations. |
Random Offset | You can use a random offset to change the starting playback keyframe for the animation on a per-particle basis. |
Random Table | The random table randomly obtains a value at particle emission time from the animation frame. |
Provides a simple way to create particle alpha animation without using the Curve Editor.

Specifies a value of 0.0 to 1.0 for the duration the particle changes between the alpha animation start-time value and alpha animation mid-time value.
Specifies a value of 0.0 to 1.0 for the time the particle starts to change between the alpha animation mid-time value and alpha animation end-time value.
Specifies the alpha value of the particle when the animation starts.
Specifies the alpha value of the particle at the mid-point time between the start and the end of the animation.
Specifies the alpha value of the particle when the animation ends.
