Keyframe Editing
It will be active by default, but you can toggle it with the key-shaped button in the toolbar.
This is the simplest way to describe how stuff in your scene should animate. Create keyframes in property tracks that are snapshots for what values that track should have at specific times, then control how the track should blend between those values.

Creating Keyframes
There's three ways to create a keyframe for a property track:
-
Change the property that the track is bound to, a keyframe is created at the current playhead time
-
Right-click on the track in the timeline, and select Create Keyframe in the context menu
-
Toggle Create Keyframe on Click either by holding Shift or pressing the button in the toolbar, then clicking in the timeline
\
Copy the scene view's perspective into a selected camera with Ctrl+Shift+F
Interpolation Mode
Each keyframe can choose between three different interpolation modes:
- Linear - change at a constant velocity
- Quadratic - ease in / out, with 0 velocity at the keyframe
- Cubic - move along a smooth spline connecting keyframes
You can combine different modes for neighbouring keyframes to make animations ease in or out.
Automatic Track Creation
For convenience, you can enable this mode to create tracks whenever you touch something in the scene. This helps the most when you're changing lots of properties on many objects, so you don't have to manually created dozens of tracks.

Collection of curves in 3D space. Shape and behavior of the curves are controled through points `Sandbox.Spline.Point`, each with customizable handles, roll, scale, and up vectors. Two consecutive points define a segment/curve of the spline. By adjusting the handles both smooth and sharp corners can be created. The spline can also be turned into a loop, combined with linear tangents this can be used to create polygons. Splines can also be used used for animations, camera movements, marking areas, or procedural geometry generation.
Represents a CSS `@keyframes` rule.
