Model Inspector¶
Model Inspector is a Blender add-on that validates meshes, UVs, and materials for a set of common modeling mistakes, right inside the 3D Viewport.
Run a set of checks against any object and get feedback for each test and category as a pass/warning/error breakdown. You can jump straight to the problem geometry with a single click! No more hunting for mystery errors in your models.

Why use Model Inspector?¶
Modeling mistakes are easy to make and easy to miss. N-gons buried in a dense mesh, UV islands that drifted out of bounds, material slots that get left empty after a merge. Model Inspector catches these before they turn into a rendering bug, a broken bake, or a rejected asset.
- Three check categories — (Mesh, UV, and Material) — each with its own set of targeted inspections.
- Per-object results — inspect a single object or a whole batch, and see results broken down individually.
- Visual overlays — click a flagged result to highlight the exact faces, vertices, or edges in the viewport, color-coded by severity, then use the magnifying glass to zoom straight to it.
- Non-destructive — Model Inspector only reads your scene. It never modifies geometry, UVs, or materials.
Requirements¶
- Blender 4.2 or newer (Model Inspector is a Blender extension).
What gets checked¶
| Category | Checks |
|---|---|
| Mesh | Ngons, tris, loose vertices, non-manifold edges, doubles, interior faces, inverted normals, unapplied transforms, high-valence vertices |
| UV | Missing UV maps, too many UV maps, overlapping UVs, zero-area UVs, UVs outside 0–1 bounds, stretched UVs, inconsistent texel density |
| Material | Missing materials, empty material slots, faces with no material, missing image textures, duplicate materials |
