I can confirm I'm seeing the same behavior as well. Basic properties like boundingBox on SCNNodes fail in pretty spectacular ways. This basically kills the app =\ Would love to hear some news about what's up. Is this just the way we figure out to switch to RealityKit?

Hey there, any chance you have a solution for this lying around? I'm trying to use a set of views instead of rendered view images for the sake of performance, and this would be a great tool to try.
