From 04d53d7d6f4f1059bc15fd296d374e0e8addb88b Mon Sep 17 00:00:00 2001 From: jichuanh Date: Wed, 8 Jul 2026 11:55:19 +0000 Subject: [PATCH 1/8] Add the Shadow camera manager counterpart Manager-based counterpart for the Shadow Hand camera reorientation task with Play and Benchmark variants, registered with the rendering correctness suite and reference golden images for both the Direct and manager camera tasks. Validated by full camera manager training and rendering-correctness runs on RTX. --- .../task-cleanup-dex-part10.minor.rst | 5 + .../reorient/config/shadow_hand/__init__.py | 70 ++++++++
