Rebuilt for Blender 4.2–5.2 as an extension. Three tools: Slice (exact, seam-safe tiles), LOD (seam-safe LODs for tiles or any mesh), Export (FBX/glTF per tile for Unity, Unreal, Godot). UPBGE LOD setup is experimental. 1.0.3: UPBGE 0.50 LODs applied at game start; large LOD builds get a warning, progress and Esc cancel; no Decimate warnings on tiny tiles.
