Using Value Clip Animation with USD

[bogusindustries]

Is it possible to use Value Clip Animation with USD?

We’re creating assets in Houdini and saving out the animation via Value Clips. So far all I can find for animation is a single file approach, but our animation is animated prim variables saved out as a sequence. Has anyone been successful with that approach or is it just not a supported feature yet?

Yes, it is possible to use Value Clips with USD (Universal Scene Description) to manage animated prim variables saved out as a sequence. Value Clips are designed to enable efficient management and playback of time-sampled data by organizing them into separate files rather than embedding all animation data into a single USD file. This approach can be beneficial for managing large datasets and improving performance

Thanks for the reply! I know USD supports them and they work without any additional work in Maya for example. However, I haven’t seen an example or documentation of how to set them up in Unreal. The USD comes into the stage editor with a Level Sequence and a Time track that is the correct length, however, nothing happens when scrubbing the track or playing the game. How do I get the time track to read the value clip files?
