4DViewsTest3 is a Unity project where I'm trying several VFX ideas with 4DViews volumetric videos and the realtime ray tracing features (DXR) of Unity HDRP.
The volumetric video data files are missing from this repository. You can download them from the Resources page of the 4DViews site.
You have to convert the texture files into a HAP encoded .mov file. Use ffmpeg.sh for the conversion.
