Editor plugin for Unreal Engine 5 that colors meshes in the viewport by their LOD0 triangle count like Shader Complexity, but for geometry weight.
Helps you find the heaviest meshes in your scene at a glance.

Key features:

• Per-mesh triangle count visualization with customizable color ranges

• Post-process + Custom Stencil rendering mesh materials are never modified, fully save-safe

• Per-instance counting for Foliage, ISM, and HISM

• Supports Static Meshes, Skeletal Meshes, Nanite fallback proxies, and World Partition external actors

• Camera radius filter and auto-follow for scenes with 1M+ actors

• Three interpolation modes: Stepped, Smooth, and Smooth Log (for wide dynamic ranges)

• Configurable Custom Stencil range to avoid collision with outline / highlight systems

• In-viewport legend with live min / median / max stats

• Force LOD0 toggle for accurate displayed counts

• Auto-deactivates safely before Save, PIE, and editor close
  

Use cases:

• Foliage optimization in open worlds

• Polygon budget diagnostics during pre-production

• Reviewing assets from outsource teams

• Educational visualization of mesh cost
  

Editor-only no runtime impact, not included in packaged builds.

Tested on Unreal Engine 5.7 (should also build on 5.8).

Free for personal use.
