12 Free Blender Fab to Godot 4.5 glTF Scale and Import Proof Tools (2026)

Full handoff spine—ORM, UE .uplugin, Unity import; this list owns Godot 0.01 scale proof only.
After scale pass: graduate to 25-tool ORM lane

Upstream charter—`fab_pipeline_receipt_v1.json` + moratorium before Blender queues scale.
Pro tip: one proof mesh per kit

#1 Fab scale fix—Ctrl+A → Scale before glTF export; never ship 0.01 object scale to Godot.
Pro tip: proof sphere at scale 1,1,1 first
Kit imports tiny? Godot 0.01 scale fix

Export lane—+Y up, applied transforms, no hidden 0.01 scene unit cheat for UE-only presets reused in Godot.
Use for: Fab environment GLB

Godot 4.5 import baseline—reimport after Blender fix; do not compensate with permanent root scale hacks.
Best for: fest demo props

Root scale audit—inspect import hierarchy when kit spawns tiny; compare bounding box to Blender dimensions.
Pair with: proof sphere smoke

Pre-import gate—catch bad accessors before Fab kits hit fest branch CI.
Log in: fab_pipeline_receipt P5 row

Regression proof assets—Duck/Box baseline when debating importer vs artist kit scale.
Use for: ±1% bounding-box compare

Unit-scale discipline—0.01 vs 1.0 scene units; same mental model when UE presets leak into Godot glTF.
Cross-engine: scale vocabulary

Material lane sibling—after scale proof passes, fix metallic/roughness channels—not speck-size props.
Order: scale first, ORM second

Why kits pile up—integration hour bands + scope creep when scale proof skipped.
Use for: producer alignment

Receipt gate—attach fab_pipeline_receipt_v1.json with scale_proof_pass + validator log before fest promotion.
