godot-export-gltf

Python script to export glTF 2.0 scenes from the Godot game engine

To use:

You'll need Godot v3.0.2 or later, and godot-python. You'll also need a local numpy installation in your godot-python. (This script assumes it's in the python/ subdir, but if not, edit the line in the script.)

Once you have the godot-python pythonscript symlink in your project dir, follow the instructions at https://github.com/touilleMan/godot-python to autoload this script. Specifically, add this to your project.godot:

[autoload]
Export="*res://export_gltf.py"
[gdnative]
singletons=[ "res://pythonscript.gdnlib" ]

Then in your gdscript, call export like this:

Export.export_scene('/tmp/godot-scene/godot-scene.gltf', get_node('/root'))

Documentation

What is handled:

• PrimitiveMesh, ArrayMesh
• cameras
• lights (using KHR_lights extension)
• index and non-index mode
• transforms, materials (simple PBR only), UVs, textures, per-vertex colors
• renormalizes all normals
• coalesces vertices with "close" normals and colors, converting to index form

TO DO:

• MultiMeshInstance
• animations
• cache/dedup textures
• ambient lights
• hdr backgrounds (not in glTF yet)

HARDER:

• shaders
