Unloading(Export) a scene to an FBX file.

[SashaRX]

This feature is required for Lightmapping. For lightmapping, you need to have a final scene. If we move/rotation/scale objects in the editor, then you have to repeat the same steps in the 3d editor. Or use the 3d editor as the main tool, which deprives the team development opportunities and all the advantages playcanvas. The ability to unload a scene in FBX for work on 3d editor, would allow you to make 2uv and bake lightmaps.

Would OBJ be sufficient? That would be easier (and I think @Maksims already built an OBJ exporter for the Editor).

[SashaRX]

Obj format only stores geometry information, it does not store light sources information.

[Maksims]

We've used OBJ before, but GLTF would be way more useful as Sasha mentioned: it would store not only geometry but also lights.
Could also support textures. This would be even better.

@Maksims - Sasha is asking for FBX, not glTF.

Both will work in his case. He is using it to import into Unity/3Ds Max, to bake lightmaps.

Also GLTF writer is probably easier than FBX writer.

[willeastcott]

It certainly is easier. So should the title be changed to 'Scene export to GLB'? 😄

[SashaRX]

*.glb and *.gltf don't native export/import in 3ds max, I can't speak for the latest versions, but 2018 definitely not.
