Features

Detailed coverage of Boop's features — automatic surface transfer, UV generation, batch LOD generation, GPU preview, and more.

Automatic Surface Transfer

Boop's core differentiator is automatic surface transfer. After decimation, Boop regenerates UVs and transfers surface data from the original mesh to the simplified result. This means:

  • Fresh UVs are generated automatically on the simplified mesh
  • Normals, vertex colours, and custom attributes are projected from the original
  • Baked textures are re-mapped to the new UV layout automatically, aiming at optimal texel usage

The pipeline automatically transfers the following surface data:

  • Normal transfer — projects high-poly normals onto the simplified mesh
  • UV transfer — re-maps UVs from the original when needed
  • Vertex colour transfer — preserves painted vertex data
  • Custom attribute transfer — handles any custom mesh attributes

Surface transfer runs automatically as part of the decimation pipeline — no extra steps required.

Batch Multi-LOD Generation

Generate multiple LOD levels in a single operation:

  • Define up to 6 LOD levels (LOD0–LOD5) with individual target ratios
  • All LODs are generated from the original mesh (not cascaded) for maximum quality
  • Output objects are named automatically: MeshName_LOD0, MeshName_LOD1, etc.
  • Organises LODs into a collection hierarchy

Hierarchy Processing

Process entire object hierarchies at once:

  • Select a parent object and Boop will process all child meshes
  • Maintains parent-child relationships in the output
  • Respects per-object overrides for target ratios
  • Ideal for complex game props and characters with multiple mesh parts

GPU Preview Overlay

Visualise simplification quality directly in the viewport:

  • Wireframe overlay shows the simplified topology over the original mesh
  • Heatmap mode highlights areas of UV distortion or geometric error
  • A/B toggle switches between original and simplified in real-time
  • Runs on the GPU for smooth interaction even with dense meshes

Quality Auto-Analysis

Let Boop choose the optimal reduction level:

  • Analyses mesh topology, UV layout, and curvature
  • Suggests a target ratio that stays within your quality threshold
  • Reports a quality score (0–100) for each LOD level
  • Flags regions where quality drops below acceptable limits
