Check Mode: Fix Models While Watching the Results
Check Mode is the core feature of YL MeshCheckHUD.
It displays common topology issues directly on the model and shows the count of each issue type in the sidebar list.
You can fix the model while watching the results update, without manually refreshing the check.
Supported checks:
- Ngons
- Overlapping vertices
- Loose vertices
- Needle triangles
- Tiny faces
- Poles
- Non-manifold edges
- Missing sharp edges
Realtime HUD: View Key Mesh Information While Modeling
Realtime HUD displays commonly used mesh information directly in the 3D viewport, such as the triangle count and dimensions of the selected mesh. Whether you select the whole object or part of the mesh in Edit Mode, the HUD shows the result directly in the viewport.
It can display:
- Triangle count of the current model
- Dimensions of the selected object
- Statistics for multiple selected objects
- Dimensions of selected vertices, edges, or faces in Edit Mode
- Unapplied scale warning
Heatmap Preview: Quickly Find Objects With Unusual Complexity
Heatmap Preview uses color to visualize the triangle count of objects in the scene. It also shows each object's triangle percentage, material / material slot count, and UV count in the list and HUD.
Suitable for checking:
- Object triangle count
- Triangle percentage in the scene
- Material count / material slot count
- UV count

What's New
1.1.0 June 27th, 2026
YL MeshCheckHUD 1.1.0
Added a new Edit Mode check detail view
- The check results panel now provides a more focused single-object detail view in Edit Mode. This makes better use of the sidebar's vertical layout, making it more intuitive and convenient when checking objects one by one.
Fixed important compatibility and stability issues
- Fixed an issue where enabling the add-on could interfere with Blender's native "Mark Bevel Weight" and "Mark Crease" commands in the right-click menu. This was fixed by removing BMesh reads from the viewport draw callback; the draw callback now only reads the plugin's existing overlay cache.
- Fixed several known bugs and polished UI details, including result visibility display, heatmap refresh behavior, HUD information display, and material / UV result updates.
Thanks
- Thanks to brunoosti and xieqsei for their valuable feedback and suggestions.
