Channel channel node

Creates channels from the value of its parameters.

This chop allows you to create channels that replicate the values of its parameters through time. Each channel can be named and assigned a different value. The parameter is then evaluated for each frame in the scene file.

This operator can be created from existing channel groups by right-clicking on the name in the Channel Groups list and choosing Create Channel CHOP…

Parameters

Data

Copy to Export

Copies the animation from its Value parameters to where the channels are currently being exported to.

One Key Per Sample

Instead of evaluating the Value parameter every frame, create the channel such that each sample corresponds to a key on the Value parameter. This is only meaningful if the Value parameter is animated.

Number of Channels

Number of channels to create.

Name

Name of the channel to create. If the size is greater than 1, then the letter x,y,z, or w is appended to the channel name depending on if it is the first, second, third, or fourth component of the Value parameter respectively.

Type

Type of channel to create.

Float	Regular float parameter
Euler Rotation	A quaternion attribute is added to the three generated channels.

Rotate Order

If the type is Euler Rotation, this parameter specifies the order of rotation.

Size

Number of components. If the type is Euler Rotation, this parameter has no effect since 3 components must be generated.

Value

The values of the channels.

Channel

Channel Range

Specifies the range of data to generate.

Use Full Animation Range	All of the animated range.
Use Current Frame	Only the sample at the current frame.
Use Start/End	The range is specified from the Start and End parameters.

Start

The start time of the channel range.

End

The end time of the channel range.

Sample Rate

The sample rate of the CHOP.

Extend Left

The left extend condition (before the CHOP’s start).

Extend Right

The right extend condition (after the CHOP’s end).

Default Value

The value to use for the “Default Value” extend condition type.
