GeoLOD — Smart, UV-safe LOD Generator for Blender 4.x

Production-ready LODs in seconds – GeoLOD creates a neatly named collection of LODs from your active mesh, cleans topology with UV awareness before reduction, and applies a Decimate (Collapse) modifier, finishing with a non-applied Weighted Normals modifier (Keep Sharp off) for consistent shading.

Why GeoLOD

• UV-safe by design – optional UV seam protection during cleanup reduces stretching and keeps UV islands intact.

• Clean before you reduce – limited dissolve (small angles) + merge-by-distance removes micro-edges and garbage geometry so Decimate works more predictably.

• Consistent shading – every LOD gets a Weighted Normals modifier (left unapplied), so you can tweak later.

• Organized output – all LODs are placed in a BaseName_LODs collection, named BaseName_LOD1…N (+ optional LOD0 copy), each with a LOD_Level custom property.

• Simple, predictable controls – set LOD Count and either paste exact Percentages (90,80,65…) or use Start % + Step %.

• Non-destructive when needed – choose whether to apply generated modifiers (Weighted Normals is always left unapplied).

Key Features

• Generate 1–10 LODs in one click.

• Exact percentage list or Start/Step pattern.

• UV-aware cleanup (Limited Dissolve with angle limit, Merge by Distance, optional UV seam protection).

• Decimate (Collapse) – creates triangulated reduction for optimal real-time performance.

• Auto-add Weighted Normals (Keep Sharp = OFF), left unapplied.

• Optional LOD0 (copy of original).

• Preserves materials, vertex colors, and UVs where possible.

• Works with Blender 4.0+.

Workflow

1. Select a mesh object in Object Mode.

2. In N-panel → LOD Maker, set Base Name, LOD Count, and either Percentages or Start/Step.

3. (Optional) Enable UV-safe Smart Cleanup and tweak angle/merge distance.

4. Click Generate LODs. Your LODs appear in BaseName_LODs.

Output Naming

• Collection: BaseName_LODs

• Objects: BaseName_LOD1…LOD{N} (+ optional BaseName_LOD0)

• Custom property: LOD_Level = 0..N

Compatibility & Notes

• Blender 4.0 or newer.

• Mesh objects only. GeoLOD duplicates the object with a unique mesh data-block; materials remain linked.

• Extreme reductions will affect shape and UVs — keep reasonable percentages for hero assets.

• Decimation uses triangulated geometry for performance; quads are not preserved.

• For predictable results with heavy upstream modifiers (Mirror/Array/Subdiv), either apply them first or let GeoLOD apply all except Weighted Normals.
