Playback Options

Playback Options

Playback Options are options to configure playback of an animation created in the CurveEditor panel along the specified timeline.

Fit to Lifetime

Fit to Lifetime is a playback option that automatically links animations created on the Curve editor panel with particle lifetimes.

The figure below shows how the Fit to Lifetime option links an animation created with 20 frames to the particle lifetime.

Fit to Lifetime

Using the Fit to Lifetime option, an animation created with 20 frames is linked to the 40-frame particle lifetime.

When using Fit to lifespan, it is necessary to create an animation curve for the period representing the average lifespan to account the fact that curves are baked when outputting data.

Specify Frame Count

Specify Frame Count is a playback option that loops animations created in the Curve editor panel based on the specified frames. You can configure the number of frames per loop cycle and the random offset.

A loop animation is an animation in which the ending frame transitions smoothly into the starting frame. To create one, create an animation curve that will transition smoothly when looped.

The figure below shows an example using an animation originally created with 20 frames, with 15 frames per cycle and a random offset.

Specify Frame Count

Frames per Cycle

This specifies the number of frames in a single loop cycle when looping animations created in the Curve Editor panel.

Random Offset

You can use a random offset to change the starting playback keyframe for the animation on a per-particle basis.

Random Table

Random table is a playback option for getting a value at the time of particle emission from a random animation frame.

The figure below shows how a value used when a particle is emitted is obtained from a 20-frame animation.

Random Table

To use playback options with animations created using the Add to Previous Value method, you must create your animation in the Curve Editor panel.
