To play and capture splat sequences in Unity, using one .ply file per frame, follow these steps:

1. Download and configure Unity Gaussian Splatting.
2. Replace GaussianSplatAssetCreator.cs in that project with the version in this directory. This replaces single splat file conversion with conversion of an entire directory of splat files.
3. Export a splat sequence from GSOPs in Houdini using Frame Range export mode in the Gaussian Splats Export node.
4. Convert your exported splat sequence and place the converted assets into an asset subdirectory (e.g., Assets/GaussianSplatAnimations/MySplatSequence).
5. Add LoadSplatSequence.cs to the Unity 3DGS Playground project.
6. Add LoadSplatSequence as a component to the GaussianSplats GameObject.
7. Set the SplatAssetsDirectory to the path from step 4.
8. Play the game and watch your gaussian splatting animation.
9. Leverage Unity API's ScreenCapture.CaptureScreenshot to "render" your animation.
