Old network
As of Houdini 20.5, use Copernicus nodes instead of Compositing nodes. Though both networks still exist, the Compositing network is now designated as COP Network - Old. The Compositing network and its nodes will be deprecated and then removed in a future Houdini release.
This operation merges the planes of several inputs together. Most of the parameters determine how to handle differences in the sequences, such as image size, frame range and plane conflicts.
Parameters ¶
Plane Conflict
Planes from different inputs with the same name are in conflict. A conflicting plane is the second plane or later which matches an existing plane name. This parameter determines how to resolve the conflict.
Rename Conflicting Plane
The plane is renamed by adding a unique suffix number.
Add to Plane Array if Identical else Rename
A plane array is created if the planes' data format and structure match, otherwise the conflicting plane is renamed.
Add to Plane Array if Identical else Ignore
A plane array is created if the planes' data format and structure match, otherwise the conflicting plane is not merged in.
Ignore Conflicting Planes
Any conflicting planes are not merged in.
Error if Conflicts Occur
A conflict flags a cooking error.
Resolution Match
If the resolutions of the inputs are not all the same, this parameter determines how to choose the output resolution.
Size
If Resolution Match is set to 'Specify a Resolution', this is the parameter which specifies the size.
Scale to New Size
If on, all inputs not matching the output resolution are scaled to the output resolution, otherwise they are cropped or extended with black.
Scale Filter
The filter to use when scaling images.
Frame Range
If the frame ranges of the inputs differ, this determines what the output range should be.
Frame Rate
If the frame rates of the inputs differ, this determines what the output frame rate should be.
Frame Match
If the frame rates of the inputs differ, this determines which input frame to pick when the cook time doesn’t reside on a frame boundary.
Input ‹n› Scope
One of these parameters is available for each connected input. Only planes listed in the scope will be merged from the given input; the others will be ignored ('*' indicates all planes). You can use the menu button to select planes from the available input planes.
