Transform Your 3D Workflow with a Professional In-Editor Normal Editing Framework. Stop wasting time exporting and re-importing models between Unity and external DCC tools (Blender, Maya, 3ds Max). BT-Mesh Smoother Pro delivers a production-ready, brush-based editing system that allows you to fix shading artifacts, blend hard edges, and perfectly smooth both static and animated meshes directly in the Unity Scene View.
Engineered for high-end 3D artists, technical artists, and indie developers who need rapid, non-destructive topology iterations.
Core Editing Modules
Dynamic Brush Engine - Spatial Hashing Performance
- Scalable Radius Painting: Paint selections intuitively with a customizable brush radius, or shrink it down to select single triangles with pinpoint precision.
- Lag-Free Execution: Powered by a custom local-space Spatial Hash grid, ensuring that brush selections remain ultra-fast and responsive even on high-poly meshes.
- Smart Eraser & Modifiers: Instantly subtract from selections using the dedicated Eraser mode or the Ctrl + Drag hotkey workflow.
Advanced Topology Selection - Smart Algorithms
- Select Hard Edges: Automatically calculates the dot product of adjacent face normals to detect and select edges sharper than your customized angle threshold.
- Symmetry Mirroring: Perfect for characters and weapons. Select one side of a mesh and instantly mirror the selection across local X, Y, or Z axes.
- Topological Actions: Rapidly expand your selection using 'Grow', 'Shrink', 'Select Linked' (Mesh Islands), or isolate specific parts using 'Select by Material'.
Precision Smoothing & Normal Control
- Angle-Based Smoothing: Intelligently merges vertex normals only if their face angles fall below a defined threshold, protecting intended hard edges while smoothing organic curves.
- Instant Visual Feedback: Enable 'Show Normals' to render real-time vertex normal lines in the Scene View, allowing you to visually verify your shading data before applying changes.
- Dual-Mode Application: Choose between localized brush-based smoothing or 1-click 'Full Mesh' processing.
Production-Ready Features
- Skinned Mesh Support: Fully compatible with both MeshFilter (Static Props) and SkinnedMeshRenderer (Animated Characters) components.
- Non-Destructive Export: Modifications don't have to overwrite your original FBX/OBJ. Save your smoothed geometry directly into your project as a new .asset file with a single click.
- Overdraw Protection: Automatically scales down debug line rendering when selecting massive areas (>30,000 triangles) to maintain high Editor framerates.
Proven Workflow Gains
- Eliminates DCC Context Switching: Keep your focus in Unity. Fix broken imported normals in seconds.
- Safe Iteration: Full integration with Unity's native Undo/Redo system prevents accidental data loss.
- Clean UI: Built entirely on Unity's modern UI Toolkit for a sleek, responsive, and professional dashboard experience.
