Remove hidden mesh geometry below terrain or inside other meshes — directly in the Unity Editor. Non-destructive, with live preview, weld & optimize. No Blender round-trip.Render-pipeline independent. Mesh Cut & Optimize works with the Built-in Render Pipeline, URP, and HDRP. The tool operates only on mesh geometry in the Editor and reuses each object's existing materials — it ships no shaders and no render-pipeline-specific code, so there is nothing to set up or convert when switching pipelines.Mesh Cut & Optimize trims away the parts of your meshes that players never see — the geometry hidden below the terrain or buried inside other meshes — straight inside the Unity Editor. No exporting to Blender, no manual re-modeling. Fewer vertices and triangles mean less GPU load and a lighter scene.Perfect for level design: drop rocks, debris, props and buildings onto your terrain, then cut off everything beneath the surface in a couple of clicks.KEY FEATURES• Cut by Terrain — remove geometry hidden under the active terrain.• Cut by Meshes — remove geometry that intersects other selected meshes (BVH-accelerated).• Per-mode Offset, Invert Cut and Cap Holes options.• Batch processing: Cut All / Re-cut All across the scene.• Non-destructive: Restore Original Mesh at any time (single or all).• Weld modes (Safe / Strict / PositionOnly) and Optimize & Cleanup for generated meshes.• Results are saved as reusable mesh assets; the editor-only marker component is stripped from builds automatically.• Console logging toggle.COMPATIBILITY• Render-pipeline independent — works with Built-in, URP and HDRP. It operates on mesh geometry and reuses each object's existing materials: no shaders, no pipeline-specific setup.• Editor-only tool (not included in builds).• Source meshes must have Read/Write Enabled in their import settings (standard Unity requirement for mesh editing).GOOD TO KNOWCuts are evaluated at the source mesh's triangle resolution, so the tool shines on reasonably detailed meshes (rocks, sculpts, scanned props). It removes hidden geometry — it is not a boolean/CSG operation (a boolean subtract mode is on the roadmap).INCLUDED• Full documentation: Quick Start, User Guide, Reference, plus a combined PDF guide.• In-Editor Help menu.Support & feedback: kidgamesoftware@gmail.com• Cut by Terrain — remove mesh geometry hidden below the active terrain.• Cut by Meshes — remove geometry intersecting other selected meshes (BVH-accelerated).• Per-mode Offset, Invert Cut, Cap Holes.• Batch: Cut All / Re-cut All across the scene.• Non-destructive Restore Original Mesh (single or all).• Weld modes: Safe / Strict / PositionOnly, plus Optimize & Cleanup.• Output saved as reusable mesh assets; editor-only marker auto-stripped from builds.• Render-pipeline independent (Built-in, URP, HDRP) — reuses existing materials, no shaders.• Editor-only. Console logging toggle. Full docs + PDF + in-Editor Help.An AI coding assistant was used during development. It helped:- write, translate into English, format the documentation and build the combined PDF;- generate a small text-based toolbar icon programmatically.All output was reviewed, tested and approved by the author. The tool's design, functionality and final code are owned by the author.
