[Bf-committers] REF: GSoC Import/Export Support

[Daniel Stokes]

Benson,

The blendergltf addon is more or less feature complete for exporting glTF
1.0 and the KHR_materials_common extension. I have not been keeping up on
potential GSoC projects this year, but last year for glTF it was more about
import.

I think Mike handled most of the original questions, but I would like to
expand a bit on the export targets. Currently blendergltf has been mostly
tested with Three.js and Panda3D, and it has options for exporting shaders
compatible with dekstop OpenGL and WebGL.

If you have any further questions regarding exporting glTF from Blender,
feel free to let me know. I can also be found lurking around the
#blendercoders channel on freenode as Kupoman.

Regards,
Daniel
