Set up and render ControlNet conditioning passes from a Blender scene for AI image/video generation - grey clay override, compositor-normalized depth, cryptomatte EXR, optional wireframe overlay for temporal consistency. Wraps scripts/setup_controlnet_passes.py (Blender 5.x APIs, test-slice discipline, trailing-dot File Output naming). Use when preparing depth/edge conditioning inputs, clay renders for video models, or crypto mattes for comp. Triggers: "controlnet passes", "render depth pass", "clay render", "grey shade render", "render passes for AI", "control net setup blender".
