GeoValueClip

The GeoValueClip node converts clips and sequences, and creates a Value Clip in the form of a USD file from the converted files.

Given a set of files which animate the same prim, this node can produce a clip which ties the animations together. As an example, you might have three layers which animate a character. You can use this node to make a sequence, or to retime, reverse or loop existing animations.

A Value Clip is the only way to animate a sequence of unanimated 3D files in files. Animated sequences cannot be read using GeoImport or GeoReference.

This node can also make a clip from a sequence of non-animated layers, such as a sequence of Gaussian Splat .ply files, converting this to .usdc. In this case, the original files are not suitable for creating clips because each file in the sequence is static and often the prim from each frame has a different name. It's more efficient to use .usdc files for reading as animations. USD has mechanisms to ensure that only the data needed to render a frame is loaded rather than loading all the frames at once which can happen with other formats.

Note:  This is a LABS node, indicated in Nuke with the tag:
LABS nodes are experimental and not intended to be used for production.
