Phase 7: Indie Game Dev Features — Batch Export, Material Presets, LOD, Mesh Validation

[fernandotonon]

Goal

Add targeted features that differentiate QtMeshEditor for indie game development.

7a. Batch Export UI

• GUI dialog wrapping CLIPipeline for multi-file conversion with progress

7b. Material Preset Library

• Pre-built presets (Plastic, Metal, Wood, Emissive, Transparent)
• Thumbnail grid, one-click apply

7c. LOD Generation

• Ogre::MeshLodGenerator with simple UI for target triangle counts per LOD level

7d. Mesh Validation Report

• Auto-check: degenerate triangles, flipped normals, UV issues
• Panel with warning/error icons + "Fix All" button

Depends on: Phase 3 (for UI integration)
Part of: UX Redesign Roadmap
