How to Inspect 3D Clues
Inspect 3D clues in The Mermaid Mask: rotate evidence objects, find hidden markings, combine notebook items, and collect all fifty clues efficiently.
Roughly half of The Mermaid Mask's fifty clues include 3D inspect mode—rotate zoomable objects in inventory or inline scene viewers to find backside markings, serial numbers, or chamfer details invisible from default angle. This mechanic powers puzzles like shape matching lock (chamfer identification) and piggy bank joint guides. Mastery dramatically reduces hint reliance and supports Master Archivist achievement.
Rotation Controls
How to Inspect 3D Clues in The Mermaid Mask
PC: right-click drag on object. PS5: hold right stick while inspecting. Switch 2: ZL + stick or mouse drag in mouse mode. Switch original: ZL precision + stick. UI displays axis gizmo when rotation available; static 2D clues lack gizmo. Double-click reset orientation (PC) or Y reset (console). Spears comments when critical angle found—audio cue plus notebook auto-update.
Hidden Mark Strategies
Check opposite faces of cauldron rubbing, payroll slip stamps, lens card backs, compass needle engravings, and pig porcelain joints. Child's Room lamp hotspot enables enhanced shading preview before shape safe attempt. Use Evidence Checklist to mark 3D-complete items.
