Composite channel node
Layers (blends) the channels of one CHOP on the channels of another CHOP.
This CHOP layers (blends) the channels of one CHOP on the channels of another CHOP. The first input is the base input and the second is the layer input.
Over the interval of the layer, the layer channels are blended with the base channels. The contribution of the layer is eased-in and eased-out according to the Start, Peak, Release and End parameters. The base is unaffected outside the interval of the layer.
The Effect parameter determines the amount of contribution of the layer.
If Base Hold is 0, the layer input will completely replace the base input when the effect is 1. If Base Hold is 1, the layer will be added to the base.
The interval of the output starts at the minimum of the base and layer. The interval of the output ends at the maximum of the base and layer. The base’s extend conditions are used if the layer lies outside the base.
If the third input is supplied, the Effect page will be overridden by the third input’s first channel, which should contain the effect values over the range of the layer.
Parameters
Composite
Base Hold | Determines how much of the base to blend into the output at points where the layer has an effect. |
Match By | Matches channels in the base input with ones in the layer input by either index or name. Channel Union causes layer channels that are not in the base to be added to the output. |
Quaternion Blend | Aids in producing smooth rotation blending. The “quaternion” attribute should be in the input CHOP. See the Attribute CHOP. |
Shortest Path Rotation Blending | If on, compensate for cyclic channels (such as angles) by always choosing the shortest route between samples when blending. |
Rotation Scope | Defines which channels are rotations for Shortest Path Rotation Blending. |
Cycle Length | The length of the cycle for Shortest Path Rotation Blending. |
Effect
Effect | Sets how much the layer affects the output. If 0, the output is the base. |
Unit Values | Sets the meaning of the next four parameters - either absolute values, relative to the start/end of the channel, or relative to the current frame. The layer and base are never shifted. |
Start | The beginning of the composite interval. Effect is zero at this point. |
Peak | Where the composite operation reaches maximum effect. This value is held until the release point. |
Release | The point at which the effect begins to fall back towards zero. |
End | The end of the composite operation’s effect. The effect reduces to zero again. |
Rise/Fall Shape | The shape of the segment between the Start and Peak indices, or between Release and End. |
Locals
| C | The current channel index (0 to NC-1). |
| NC | The total number of channels. |
