Mesh Tools

Process, optimize, and repair 3D meshes. Generate LOD chains, decimate polygon counts, fix non-manifold geometry, recalculate normals, and bake high-poly detail to low-poly meshes. Essential for game optimization and 3D printing prep.

All Mesh Tools

5 tools

Everything you need for mesh processing and optimization. From LOD generation and polygon reduction to geometry repair, normal recalculation, and high-poly texture baking. Cloud processing handles heavy meshes regardless of your device.

LOD Generator

Generate multi-level level-of-detail meshes with configurable reduction percentages for game engine optimization.

Mesh Decimator

Reduce polygon count while preserving silhouette, UV boundaries, normal seams, and vertex attributes.

Mesh Repair

Fix non-manifold edges, holes, flipped normals, zero-area faces, duplicate vertices, and degenerate geometry automatically.

Normal Recalculate

Recalculate per-vertex and per-face normals. Flip, smooth, or harden normals for correct lighting in any engine.

Texture Baking

Bake high-poly detail onto low-poly meshes. Generate normal, AO, curvature, and displacement maps from source geometry.

FORMATS

Supported Mesh Formats

Import and export across all major 3D mesh formats for game engines, 3D printing, and DCC tools.

Import Formats

OBJ (.obj): Universal mesh with UVs and materials. FBX (.fbx): Industry standard with animation data. GLTF/GLB (.gltf/.glb): Web-optimized PBR meshes. STL (.stl): 3D printing format, ASCII and binary. PLY (.ply): 3D scanner and photogrammetry data. DAE (.dae): COLLADA interchange format.

Export Formats

OBJ: Recommended for general editing and interchange. FBX: Best for game engines with animation. GLTF/GLB: Optimized for web and real-time rendering. STL: For 3D printing and rapid prototyping. All exports preserve UVs, normals, and vertex attributes.

FAQ

Frequently Asked Questions

Yes, basic mesh tools are free with a daily usage limit of 3 operations per day without an account. Mesh Decimator and Normal Recalculate are free tools. Advanced tools like LOD Generator, Mesh Repair, and Texture Baking require a Basic, Pro, or Team subscription. Visit our Pricing page for full details.
Our Mesh Decimator uses quadric edge collapse decimation, which intelligently reduces polygon count while preserving the model's visual silhouette. It respects UV boundaries, normal seams, and vertex attributes so your textures and shading remain intact after reduction. Set a target percentage or absolute vertex count for precise control.
LOD (Level of Detail) chains are multiple versions of the same mesh at different polygon counts. Game engines switch between them based on camera distance. High detail up close, lower detail far away. This dramatically improves rendering performance without visual quality loss. Our LOD Generator creates chains with 3-5 levels at configurable reduction percentages for Unity, Unreal, and Godot.
Recalculate normals whenever you see incorrect lighting, dark patches, or visible seams on your mesh. Common scenarios: after merging meshes from different sources, after 3D scanning, after CAD-to-mesh conversion, or when importing models that render with flipped shading. Our Normal Recalculate tool can compute smooth, flat, or custom-angle normals.
Mesh Repair automatically detects and fixes non-manifold edges, holes in the mesh surface, flipped face normals, zero-area (degenerate) triangles, and duplicate or isolated vertices. It produces watertight meshes suitable for 3D printing, boolean operations, and game engine import. Results include a repair report showing what was fixed and what remains.
Texture Baking transfers surface detail from a high-poly source mesh to a low-poly target mesh as texture maps. It generates normal maps (tangent-space surface detail), ambient occlusion maps (self-shadowing), curvature maps (edge and cavity detection), and displacement maps. These maps let your low-poly mesh render with the visual detail of the high-poly original in any PBR engine.
Import: OBJ, FBX, GLTF, GLB, STL, PLY, DAE. Export: OBJ, FBX, GLTF, GLB, STL. All conversions preserve UV coordinates, vertex normals, and material associations. For best results, use OBJ or FBX for general mesh processing, and STL for 3D printing workflows.
