Create over 90 types of primitive 2D and 3D meshes in both Editor and Runtime. Easily customize, preview, and generate optimized procedural meshes directly in Unity with UVs, normals, and more.For Built-in demo scene:`DemoScene-BuiltIn/*.unity`For URP or HDRP demo scene:Befor open the Scenes, Go to `Project Settings > Graphics` and assign the correct Pipeline Asset.`DemoScene-HDRP/*.unity``DemoScene-URP/*.unity`URP/HDRP scenes may show "Missing Script" warnings if opened in Built-in pipeline.These can be safely ignored or hidden if not using those pipelines.Primitive Mesh Creator is a powerful and versatile mesh generation tool for Unity that lets you create over 90 different types of primitive shapes — from flat 2D polygons to complex 3D solids — both in the Editor and at Runtime. Whether you're prototyping quickly or building custom runtime geometry, this tool delivers precision, flexibility, and speed.Using a dedicated Editor Window, you can interactively preview and configure a wide range of mesh properties such as size, height, segment count, roundness, and more using intuitive sliders. Many mesh types include advanced options like shear (skew), face culling, thickness, submeshes, and double-sided rendering — all without using shaders.Developers can also generate these meshes during gameplay using provided static C# functions, with runtime support mirroring all Editor capabilities. Additionally, the tool auto-generates ready-to-use C# code based on your current mesh setup, making it easy to copy and reuse in your projects.Whether you're a game designer, technical artist, or tools developer, Primitive Mesh Creator is an essential utility for procedural geometry in Unity.Supports Unity 2022 and Unity 6000+ (Unity 6.x).Generated meshes are fully compatible across all Unity versions.C# class dll library for Editor GUI and RuntimeEditor Support: Custom Editor Window with real-time mesh previewRuntime Support: Full static API with all Editor capabilitiesMesh Types:2D Primitives: Triangle, Rectangle, N-gon, Rounded Rectangle, Frame, Star, Parallelogram, Circle, Ellipse, Sector, etc.3D Primitives: Cube, Pyramids (Triangular, Square, N-sided), Prisms (Triangular, Square, N-sided), Cylinder, Sphere, Icosphere, Hemisphere, Egg shape, 3-Axis Cross, Torus, Helix, Rounded Cubes, and many hollow/thickened variantsand TeapotOptions per Mesh:Adjustable width, height, depth via slidersSegment control for smoothnessRadius control for circular shapesEnable/disable smoothingEnable/disable double-sided rendering (no shader required)Remove or include caps on cylindrical and conical shapesApply shear/skew transformationUV Mapping: Fully UV-mapped with live material and texture previewSubmeshes: Multi-face shapes use submeshes for individual materialsVisualization Tools:Toggle wireframeToggle normals and tangents displayShow vertex index numbers on hoverTransform Tools:Modify pivot positionRotate around X, Y, Z axesInvert mesh normalsCode Generation:Auto-generate C# code matching current settingsCopy to clipboard for use in runtime scriptsKey Features🔷 Generate 90+ customizable 2D and 3D mesh types⚙️ Real-time Editor Window with intuitive sliders and live preview🧩 Full runtime API for procedural mesh generation during gameplay🧱 Support for hollow, capped, rounded, and smoothed variants🎯 Precision control over size, segment count, shape roundness, and shear🧵 Built-in UV mapping and submesh support for multi-material setups🧭 Toggle wireframe, normals, tangents, and vertex indices🔄 Transform tools: pivot adjustment, rotation, normal inversion🧪 Export C# mesh generation code for direct runtime use💡 Works in URP, HDRP, and Built-in render pipelines✅ No third-party dependencies or shaders requiredAdditional Features - Mesh Tool APIInvert NormalChange PivotTranslate verticies (not by GameObject Transform)Get Geometry Center PositionMerge two meshesRotate X, Y, Z (not by GameObject Transform)Make Both Side (not by Shader)
