- Create an empty Unity project.
- Import the spine-unity.unitypackage you downloaded. (double-clicking on the unitypackage should open it in Unity).
- As with Unity updates, it is always recommended that you back up your whole Unity project before performing an update.
- Always check with your Lead Programmer and Technical Artist before updating your Spine runtime. Spine runtimes are source-available and designed to be user-modifiable based on varying project needs. Your project's Spine runtime may have been modified by your programmer. In this case, updating to the latest runtime also requires reapplying those modifications to the new version of the runtime.
- Read the
CHANGELOG.mdfile included in the downloaded unitypackage or on github. You can find the necessary documentation here when obsolete methods have been replaced with new counterparts.
- Open your Unity project.
- Import the .unitypackage into your existing project by double-clicking on the unitypackage file or dragging it into Unity editor Project view.
- The Import dialog will show which files are updated and will update them regardless of where you moved them in your project since you last imported.
- This functionality may not work correctly if your meta files were corrupted or replaced. In that case, you may have to do delete the old version of the runtime before importing the unitypackage.
- Much older versions of the unitypackage had inconsistent meta files for spine-c#. You may have to delete the older spine-csharp folder when updating. This otherwise works correctly.
- Occasionally, major refactoring involves removing or merging some files. Importing the .unitypackage will not delete those leftover files when you update so you may have to do that yourself. Check here for announcements regarding changed/leftover files: http://esotericsoftware.com/forum/Noteworthy-Spine-Unity-Topics-5924
For more options, see the spine-unity documentation page section on updating.
- Download the Unity Package Manager (UPM) package via the download links above or find it in the spine-runtimes/spine-unity/Packages subdirectory on the git repository.
- If you have your Unity project open, it is recommended to either a) close Unity or b) close any scene containing Spine components (e.g. by opening a new empty scene).
- You can then either unzip (or copy if using git) the package to a) the
Packagesdirectory in your project where it will automatically be loaded, or b) to an arbitrary directory outside the Assets directory and then open Package Manager in Unity, select the
Add package from disk..and point it to the package.json file.
- The Project panel should now show an entry for your package, e.g.
Spine Lightweight RP Shadersunder
Packages. If the directory is not yet listed, you need to close and re-open Unity to have it display the directory and its contents.
- The same principles as updating the Spine Unity runtime apply.
- As mentioned above, it is always recommended that you back up your whole Unity project before performing an update.
- If you have your Unity project open, it is recommended to either a) close Unity or b) close any scene containing Spine components (e.g. by opening a new empty scene).
- Copy the content of the new UPM package zip file or git directory over the existing one. Depending on how you have installed the UPM package, this will be either the `
For more information, see [this forum topic](http://esotericsoftware.com/forum/Spine-editor-and-runtime-version-management-6534). **Fixed Bugs** * (2019 Jul 17) Note: A lot of restructuring has been performed, please consult the CHANGELOG.md file for further info. * (2019 Jul 17) Fixed json curve import: was mis-interpreting curves as linear instead of a smooth curve. * (2019 Jul 17) Fixed a bug in SpineMecanim which caused dipping to SetupPose during transitions due to MixBlend.Replace on first track. * (2019 Jul 10) Fixed example asset stretchyman normal and emission maps. * (2019 Jul 10) Changed default `sRGB (Color Texture)` attribute at spine atlas texture import back to `true`. This creates consistent and correct look in linear and gamma color space which is more important than rare mipmap problems. * (2019 Jun 18) Fixed runtime import hanging on "Importing small assets" in Unity 2019.3 and creating multiple Assets/Editor1-N dirs. * (2019 Jun 16) Fixed a crash upon importing realted to stencil mode auto-updater. * (2019 Jun 13) Fixed root bone transform for skeleton scale to use world axes. * (2019 Jun 03) Fixed endless loop in Unity Editor when updating assets due to stencil parameter auto-update. * (2019 May 28) Fixed Spine shaders not displaying on Nintendo Switch. * (2019 May 15) Fixed a rare bug regarding incorrect attachment state after multiple transitions.

This stores Spine settings in Assets/Editor/SpineSettings.asset which can be shared with team members. * (2019 Apr 25) Fixed initial animation not being mixed out in some circumstances due to PoseSkeleton call. Removed PoseSkeleton and PoseWithAnimation extension methods to prevent related issues on user side.

This affected tangent calculations for SkeletonRenderers that used multiple submeshes and materials. * (2018 Nov 12) Fix SkeletonRenderSeparator not updating when instantiated in Unity Editor edit mode. * (2018 Nov 12) Fix SkeletonGraphic runtime instantiation not having a required material parameter. * (2018 Nov 12) Fix SkeletonUtility not following IK bones correctly. * (2018 Oct 24) Fixed WorldToLocalRotation and LocalToWorldRotation rotation transformation functions on the Bone class to account for local rotation and shearX. * (2018 Oct 18) Fixed MeshGenerator disposing previously created buffer objects, potentially causing unnecessary GC alloc when per-submesh branch of mesh generation is used. * (2018 Oct 17) Fixed MeshGenerator causing GC alloc per frame when per-submesh branch of mesh generation is used, such as when ClippingAttachments are active. * (2018 Oct 8) Fixed SkeletonRenderer/SkeletonAnimation skin field not applying changes reliably when multi-editing. * (2018 Oct 8) Fixed obsolete code causing warnings from using flip instead of scale in SkeletonFlip timeline mixer. * (2018 Oct 8) Fixed data reloading when SkeletonRenderer/SkeletonAnimation/SkeletonGraphic had missing textures and materials when switching from play mode to edit mode. * (2018 Oct 1) Fixed an bug where cloned linked meshes would not retain the original MeshAttachment color. * (2018 Sep 25) Fixed an issue where Rigidbody2D would be added at runtime without warning. * (2018 Sep 24) Fixed an issue where SkeletonAnimation and SkeletonGraphic Initialize raises the first events, which causes them to skip those events on the first Update. First events should now be correctly raised on the first Update. * (2018 Sep 24) Fixed a bug where initial flipX and flipY would be copied to all selected Spine objects when multi-selected in Unity editor. * (2018 Sep 10) Fixed a bug where AnimationState would cause an infinite loop from a cycling linked list. * (2018 Aug 25) Fixed a bug where using GetRemappedClone without PMA would result in an attachment without a Material. * (2018 Aug 25) Fixed a bug where rotation timelines would spin indefinitely. * (2018 Jul 17) Fixed a typo in the conditional compile for Unity 2017.2 and above. * (2018 Jul 2) Fixed a bug where AtlasUtilities.GetRepackedAttachments would have misaligned arrays when your attachment list had non-renderable Attachments. * (2018 Jun 7) Fixed an issue where a Spine-generated mesh would leak if you force-reinitialized a SkeletonRenderer/SkeletonAnimation/SkeletonAnimator. * (2018 May 25) Fixed an issue where the first frame of a (Unity Timeline) SpineAnimationStateClip playing would not visually reflect the new animation despite having no mixing. * (2018 May 24) Fixed a bug where skeleton previews were not working, or animation previews were playing too fast. * (2018 May 10) Fixed a bug where clipping would function incorrectly with SkeletonRenderSeparator. * (2018 Apr 12) Fix case where Tint Black was used and no attachments were rendered causing a NullReferenceException. * (2018 Mar 27) Fix SpineAttributes not correctly detecting sibling or base properties, especially when array fields are involved. * (2018 Mar 23) Fixed new tangents not being solved every frame. * (2018 Mar 14) Fix DrawBoundingBox. * (2018 Feb 8) Fix "none" item for SpineSlot attribute. * (2018 Jan 12) [AnimationState] Fixed incorrect delay being calculated for non-loop animations. * (2018 Jan 9) Fixed previous BoneFollower fix not applied to world-space Transform mode. * (2018 Jan 8) Fixed BoneFollower adding redundant rotation when bone is locally flipped and BoneFollower is following local scale. * (2018 Jan 6) Fixed SkeletonAnimator not caching clip info in existing lists in Unity 5.6. It caused memory allocation per frame. * (2018 Jan 5) Fixed SkeletonAnimator's MecanimTranslator not clearing completely when calling Initialize. * (2017 Dec 24) We've temporarily removed the included asmdef file until we can add and arrange the editor assembly definitions so that building for the target platform works. * (2017 Dec 22) Fixed the BoundingBoxFollower inspector not correctly initializing the BoneFollower it creates through the Add BoneFollower button. * (2017 Dec 15) Fixed a Clipping attachment bug where clipping would not stop if the end slot was empty or non-renderable (eg, had a BoundingBoxAttachment, PathAttachment or PointAttachment). * (2017 Dec 7) Fixed handling of play-pause in the SkeletonDataAsset inspector. * (2017 Nov 13) Fixed the Drag-and-Drop cursor tooltip "Create Spine GameObject" not showing up. * [See history...](http://esotericsoftware.com/spine-unity-history#Fixed-Bugs) **Important notes when upgrading** * (2017 October 16) The old AttachmentTools static class called `SpriteAtlasAttachmentExtensions` was renamed AtlasUtilities. Any methods that were called as statics rather than extension methods must now refer to that new name. Extension method calls will not need any code changes. * (2017 June 11) SkeletonGraphic now allows you to override the mainTexture with a repacked texture using SkeletonGraphic.OverrideTexture. * (2017 May 6) Sprite Shaders: When updating shaders from any source, especially ones that use cginc files, it may be necessary to restart Unity or right-click then choose `Reimport All` in the project panel so the cginc files are properly reimported. https://forum.unity3d.com/threads/is-there-a-way-to-force-shaders-to-update-when-cginc-files-are-updated.336041/ * (2017 May 6) Sprite Shaders: Some files from the older version of the Sprite shaders were removed. delete the whole `spine-unity/Modules/Shaders/Sprite` subfolder before upgrading to ensure no old unused files are left behind. * (2017 May 6) Sprite Shaders: Updated to the latest source version. Some serialization may have changed. If you used these shaders, do go over your Material assets and make sure they have the correct settings: https://github.com/traggett/UnitySpriteShaders * (2017 Mar 30) You now have the option to disable multi-mixing to get rid of the dipping issue. This can be set with the `AnimationState.MultipleMixing` bool property. In 3.5, it is enabled by default so updating your runtime will not result in unexpected changes in animation behavior. You can change the code so AnimationState sets the value to false by default to remove unwanted dipping at the cost of multiple mixing. This default may change in 3.6. * (2017 Jan 24) Based on Unity Technology recommendations, whenever SkeletonUtility (or BoundingBoxFollower) generates PolygonColliders based on Spine Bounding Boxes, it will also add a Kinematic Rigidbody2D to that object. This means each of those GameObjects are their own immutable box2D body and cost significantly less computationally to move/animate. * [See history...](http://esotericsoftware.com/spine-unity-history#Important-Notes-when-Upgrading) ---------- ## Older Versions **Spine-Unity 3.6 for Unity 5.6-2018.2:** https://esotericsoftware.com/files/runtimes/unity/spine-unity-3_6-2019-05-13.unitypackage (Last updated: UTC - 2019 May 13) **Spine-Unity 3.6 for Unity 5.4:** http://esotericsoftware.com/files/runtimes/unity/spine-unity-3_6_Unity-5_4-2017-06-20.unitypackage (Last updated: UTC - 2017 June 20) **Spine-Unity 3.5 for Unity 5.4-2017.1:** http://esotericsoftware.com/files/runtimes/unity/spine-unity-3_5_Unity-5_4.unitypackage (Last updated: UTC - 2017 June 18) **Spine-Unity 3.0 for Unity 4.6:** http://esotericsoftware.com/files/runtimes/unity/spine-unity-3_0_Unity-4_6.unitypackage (Last updated: UTC - 2017 May 9)
