Documentation
Missing Runtime textures? Import every texture referenced by the atlas without changing its filename or relative location.
Missing source images? Keep the entire images folder beside the .spine project.
JSON loading error? Match the runtime to the export's 4.3 version line.
Animation not found? Check its exact name and that it is included in your purchase.
Choose matching texture and material settings: Straight alpha + Bleed for the straight download, or premultiplied alpha for the PMA download. PMA is a separately generated archive; the original package, purchased animation set and saved events stay unchanged. Do not premultiply the PMA textures a second time.

Validation covers the exported data with spine-csharp 4.3. Engine-specific integration and rendering settings must be checked in your target engine; this is not a claim that a Unity, Unreal or Godot project is included or tested.
Limitations
Runtime purchases contain exported animation data, not the editable project. Editable Source includes the .spine project and source PNG artwork, plus complete Runtime access. PSD, engine projects, gameplay code and Spine editor/runtime software are not included. Editing requires an appropriate Spine Professional license; runtime use is subject to Esoteric Software licensing terms.
