Scale can be used to change the scale of particles and configure animations.
The settings available for Scale (expanded) are the same as for Scale.
This page describes scale settings and features.
A | Animation | Select whether or not to animate the particle Scale. |
---|---|---|
B | Default | Sets the default value for particle scaling. Additional corresponding items are displayed when setting an animation. |
C | Runtime Setting | To read about the Enable checkbox and resource copying, see here. |
The following four items can be selected when setting a scale animation.
Item | Description |
---|---|
Do not animate | Scale animation is not performed. |
Add to Previous Value | Select this when you want to animate at a set speed. |
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. |
Note: Settings items including default values change for the selected animation.
Select this option when you do not want to animate particle scale.
Set standard values only.
Selecting this option allows separate settings for X, Y and Z axes using values standard to scale animations.
Setting an Amplitude (%) applies a random value to the scale at time of particle generation.
Select this option when you want to animate at a set speed.
Set the standard value and the default value to be added to the previous value.
This setting is the same as Do not animate.
Default values to be added can be set for each of the X, Y and Z axes.
Default values are added to standard values each frame to animate at a set speed.
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. |
Select this when you want to create an animation using a curve.
Sets the default value used to overwrite the previous value.
Selecting Overwrite previous value causes settings set to standard values to be lost.
Use Scale (extended) when setting standard values or amplitude (%).
The value from the previous frame is overwritten with the default value.
If an animation has been created on the CurveEditor panel, the value from the previous frame is overwritten with the created animation rather than the default value.
Provides a simple way to create particle scale animation without using the Curve Editor.
For details about overwrite previous value using four-key method, see here.
Specifies a value of 0.0 to 1.0 for the duration the particle changes between the scale animation start-time value and scale animation mid-time value.
Specifies a value of 0.0 to 1.0 for the time the particle starts to change between the scale animation mid-time value and scale animation end-time value.
Specifies the scale value of the particle when the animation starts.
Specifies the scale value of the particle at the mid-point time between the start and the end of the animation.
Specifies the scale value of the particle when the animation ends.
This is the same setting as Add to previous value.
The settings available for Scale (extended) are the same as for Scale.
Note: The Scale (extended) item displays when the Use checkbox is marked.
Use Scale (extended) when an Amplitude value is set in the scale's standard values and Overwrite Previous Value is set for Animation.
