Pre-Flight | Game-Ready Asset Validator

• ✓Checks transforms (unapplied location/rotation/scale, non-uniform and negative scale flagged, never silently baked), pivots/origins, topology (ngons, non-manifold edges, loose verts, zero-area faces, doubled vertices), UVs (missing maps, missing UV2 lightmap channel, degenerate/stacked/overlapping UVs), naming, real-world scale, textures (missing files, overkill resolutions), and scene hygiene (empty objects, true duplicate materials detected by node-tree fingerprint)
• ✓Engine rule profiles, UE5, Unity, or Godot 4: every threshold, budget, and naming rule adapts (SM_ prefixes and bottom-center pivots for UE5, meter-scale validation for Unity, snake_case for Godot)
• ✓Per-issue fix buttons plus Fix All Safe, one click applies every non-destructive fix, then re-runs until the scene converges to zero safe issues
• ✓Exact geometry selection, topology issues carry their vert/edge/face indices; the Select button jumps into Edit Mode with precisely that geometry highlighted
• ✓Exportable report, write the full issue list to a text file for compliance records or team handoff
• ✓Safe by design, linked library data is never touched, multi-user mesh data is skipped with an explanation, modifiers block transform baking, every operator is fully undoable, destructive fixes are never part of Fix All Safe

Compatibility: Blender 4.2 or newer; fully tested on Blender 4.5 LTS and 5.2 (118 automated checks passing on both, plus fresh-install verification).
