Editable-source (authoring) packages
What an editable edition contains, how it differs from runtime files, and where to find it when available.

Select packs offer editable-source packages for use in the Studio or another compatible glTF workflow. Editable source covers a limited set of packs, not the full catalog. Your Downloads page shows the editions your account can fetch now.
What an editable package contains#
The unit of delivery is one asset. Each editable asset arrives as its own small .zip, not as a single pack-wide editable download, so you fetch the few assets you intend to edit rather than an entire library.
An editable asset package can include:
- an uncompressed authoring GLB;
- named parts and materials;
- declared palette variants and material roles;
- a manifest describing supported editing capabilities and dependencies; and
- a README and LICENSE.
Capabilities vary by asset. Read the included manifest instead of assuming that every file has parts, slots, textures, a rig, animations, or morph targets. The manifest declares them by name, so you can check what a given asset supports before you open it:
| Capability flag | What it means when present |
|---|---|
namedParts | The authoring GLB exposes named part nodes you can select and edit. |
materialZones | Named materials map to palette keys for per-zone recolouring. |
paletteVariants | Declared colour variants, listed by name rather than a boolean. |
textures | The asset carries image textures; many low-poly assets report false. |
rigged | A skinned mesh with a skeleton is included. |
animations | Animation clips ship with the asset. |
morphTargets | Morph-target blend shapes are available. |
slots | Named attachment points for mounting other geometry. |
A vertex-coloured prop typically reports namedParts and materialZones as true with several paletteVariants, and false for textures, rig, animations, morph targets, and slots.
Runtime versus editable files#
| Runtime or pack-source GLB | Editable authoring GLB |
|---|---|
| Intended for rendering | Intended for inspection and editing |
| May join or compress geometry | Preserves declared structure |
| May bake colour into vertices | Can expose named material zones |
| Usually the smaller delivery | Usually larger and uncompressed |
Use the normal pack files in your shipped application unless you specifically need editable structure. After editing an authoring model, optimize and validate your exported runtime copy for your own target devices.
Download an editable edition#
- Sign in and open Downloads.
- Find the pack.
- Select Editable edition when the button is present.
What you receive is a set of per-asset packages rather than one merged editable pack file. An absent button means editable source is not currently available for that pack; it exists for select packs only. Editable support also differs asset by asset within a pack, so Studio shows capability and release information for individual assets separately.
Your purchase must cover the asset or pack. See Downloading your packs for the normal download flow.
Release compatibility#
Editable files are release-specific. Keep the manifest with its GLB and dependencies, and avoid mixing files from different releases unless their documentation says they are compatible. Preserve a copy used by a production project before downloading an update.
