Animation Curve Editor

Overview

The curve editor is the place to edit and finesse your key frame animation. The curve between each key will define the motion between the two keys. These frames are referred to as “inbetweens” Edit the curve via the tangent controls to define it’s shape.

Frame All

Frames the graph so all keys are drawn within view.

Frame Selected

Frames the graph so the selected keys will be focused to use the full graph space available.

Value fields

Key “frame” field

Indicates the frame the selected key is on. The user can move the key to another frame by entering a new key value in this field.

Key “Value” field

Indicates the value of the currently selected key. You can enter a new value in this field to change the key to a specific value.

Add Key

Adds transform (Translate,rotate,scale) and visibility keyframes.

Delete Key

Removes the selected key from the curve.

Copy Key

Allows you to copy a selected key - or group of selected keys from a curve.

Paste Key

Pastes the previously copied keys onto the selected curve at the location of the timeslider (current frame). You can select a different curve from to paste too from the curve list in the editor. This can be done on the same prim or to apply the copied key to the curve of a different prim.

Go to key

With a key selected - click previous or next key to select the previous or next key on the curve you are currently working on.

  • Go to Previous Key.

  • Go to Next Key.

Key movement on graph

  • Select Free to move a key in any direction on the graph.

  • Select Horizontal to only move horizontally.

  • Select Vertical to only move vertically.

Tangent Controls

../_images/anim_curve_tangents.jpg

Auto

Automatically solves a smooth tangent.

Smooth

Sets selected key to a smooth tangent. A smooth tangent aligns itself for the smoothest transition between the two adjacent keys.

Fixed

A tangent will become a fixed tangent if the user adjusts the tangent or sets it to tangent by clicking this button. A fixed tangent is a user defined tangent that does not autosolve.

Linear

The tangent points directly at the adjacent key to create a linear motion.

Stepped

A stepped key will maintain the value of the key up until the next key. There is no transition or “inbetween” between the two key values.

Weighted Tangent

A weighted tangent has a consistent length and is equidistant on both sides of the tangent.

Non-Weighted Tangent

Each tangent has a free length that the user can define.

Broken Tangent

Each of the two tangents for the key are independently controlled.

Unbroken tangent

Both tangents are locked to each other.
