on my phone now. Appologies for terse response. 1: 3x remap nodes to make interoplate for each RgB 2: combine3 node To make r g b into rgb. i hope this helps.

@KevinTho any luck here? What did you learn or discover? Thanks in advance for sharing.

Any updates for how to transcode or encode these files? I have stereo frames/video and want to encode to view on apple spatial video players.

Will the steps in the first response cause my current version of Xcode to stop working? If so, how can I get the old version back?

How did this progress? Just seeing this many years later and it still seems like scenekit has key limitation. Is finding an offramp to metalkit a typical path?
