Mesh Quality Heatmap

Mesh Quality Heatmap is a Blender addon designed to help you quickly identify and understand mesh problems directly in the viewport.

Instead of manually inspecting your model for bad topology, inconsistent normals, UV issues, or uneven texel density, the addon turns your mesh data into clear, color-coded heatmaps. Problem areas become immediately visible, making it easier to find issues and improve your assets before they reach your game or production pipeline.

With 11 dedicated analysis modes, Mesh Quality Heatmap provides visual feedback for a wide range of modeling, topology, UV, and shading problems. Each analysis uses an intuitive blue-to-red heatmap/green-to-red ..., allowing you to quickly distinguish areas that need attention.

Key Features :

• 11 mesh analysis modes
• Visualize topology and geometry quality
• Inspect UV quality and texel density
• Detect overlapping or problematic geometry
• Analyze curvature and normal deviation
• Identify potential problem areas at a glance
• Real-time viewport visualization
• Works directly in Blender's 3D View
• Supports both Object Mode and Edit Mode
• Designed for game-ready and production assets

Whether you're creating a game asset, preparing a model for baking, checking a retopology, or simply want to maintain cleaner geometry, Mesh Quality Heatmap gives you a fast visual way to find problems before they become problems.
