Hi everyone. First release from me under the name Trisect Tools.
GameExport Pre-Flight checks your models for the usual export killers, fixes the safe ones, and exports with per-engine settings, from one panel in the sidebar.
Why: I kept hitting the classics - the -89.98 rotation in Unity, wrong scale in Unreal, missing smoothing groups, batch exports full of Camera.fbx and Cube.001. The settings that prevent all of this are documented in a hundred scattered threads (plenty of them on this forum), so I put the whole checklist into a tool.
What it does:
- 13 pre-export checks: unapplied rotation/scale, negative (mirrored) scale, missing UVs, ngons, non-manifold edges, loose geometry, zero-area faces, default names, empty material slots, missing texture files, armature scale and root-bone checks. Clicking a warning selects the object.
- “Fix Safe Issues” applies rotation/scale, deletes loose geometry, removes empty slots. It never renames anything and never touches UVs.
- Engine presets: Unity (baked space transform, imports at rotation 0 / scale 1), Unreal (1:1 cm scale, face smoothing groups, tangent space, optional SM_/SK_ prefixes), Godot (.glb, modifiers applied).
- Batch export: one file per selected object, exported at the origin, scene restored afterwards. Cameras and lights skipped. Errors block export until fixed (or overridden).
Blender 4.2+, tested on 4.4. Every release goes through an automated headless test suite that exports and re-imports files to verify dimensions and transforms survive.
