Feature

Save a selected linkset (or a selection of objects) to a glTF 2.0 file (.glb, or .gltf plus files) for editing in Blender and other tools.

Scope

Geometry: prims (all shapes, including sculpties) and mesh, with each prim's position, rotation and scale relative to the root, one glTF node per prim.
Materials: PBR (glTF) materials exported as they are. Blinn-Phong materials converted to glTF metallic-roughness: diffuse texture and colour to base colour, alpha mode, normal map; specular approximated; glow and fullbright as emissive.
Textures: embedded, with the texture transform (repeats, offset, rotation) baked or carried via KHR_texture_transform.
Extras: object names and descriptions, and link order.

Permission rule: full permission only

Every prim in the selection must be:

owned by you;
created by you, or full permission (modify, copy and transfer) for you;
using only textures, mesh and sculpt maps you have full permission on.

Anything else blocks the export, with a clear message saying which prim or asset failed and why. Rigged and avatar attachments of other creators are never exportable.

UI

Right-click > Save as > glTF (pie and context menus), plus Build > Object > Export, which opens a file picker. The placeholder "Backup" and "Collada" entries in the pie's Save as menu are removed or replaced.

Later

Import of an exported file (round trip).
A full backup format that also stores inventory contents and scripts.
