The pass also uses scene depth so opaque generated field geometry resolves by nearest surface instead of draw order. Live demo compiled and planned 4 TubeField packets with 0 deferred/0 truncated; screenshot still shows generated segment structure, so the final smooth tube marcher remains a renderer-quality cut."}
