Thanks for the early warning! If this problem still persists after it is both out of alpha and beta, we will eagerly fix the issue.

[foriero]

Harald, I know it is too early but we need to move to 2021.2b1 due to URP Render Features. Is there an easy fix for this issue? Thanks, Marek.

Here is temporary fix.

Sorry for the late reply, I have been on (very short) vacation. Very glad to see that you have already fixed the issue, thanks a lot for sharing!

[foriero]

The final colors are somehow off. May it needs a bit more tweaking. Please let me know once you have it in the repository.

[Harald]

Thanks for the hint. I have created an issue ticket for it here so that it cannot get lost:
https://github.com/EsotericSoftware/spine-runtimes/issues/1912
I will let you know once it's in the reprository.

The shader compile error with URP 12.0 has just been fixed.

A new 4.0 spine-unity URP shaders UPM package is available for download here as usual:

エラーが出てしまうとのことで申し訳ありません。

お手数ですが、ファイルcom.esotericsoftware.spine.urp-shaders/Shaders/2D/Spine-SkeletonLit-URP-2D.shaderを開いて、115行目にこちらのコードがあるかどうか確認していただけますか？

#if UNITY_VERSION < 202120
return half4(CombinedShapeLightShared(half4(main.rgb, 1), mask, i.lightingUV).rgb, main.a);
#else
SurfaceData2D surfaceData;
InputData2D inputData;
surfaceData.albedo = main.rgb;
surfaceData.alpha = 1;
surfaceData.mask = mask;
inputData.uv = i.uv;
inputData.lightingUV = i.lightingUV;
return half4(CombinedShapeLightShared(surfaceData, inputData).rgb, main.a);
#endif

もし115行目にこちらのコードが表示されない場合は、UPMパッケージの更新で必要なファイルの更新に失敗しています。

このコードが表示された場合は、

#if UNITY_VERSION < 202120

を

#if 0

に変更してみてください。
これにより、常にUnity 2020.2に適したコードブランチが使用されます。

これでも効果がない場合は、別のシェーダーが使われていると思われますので、プロジェクトに同じパッケージを2つのバージョンで入れている、または同じSpine-SkeletonLit-URP-2D.shaderを2つのバージョンで入れてしまっていないか確認してみてください。

Sorry to hear you are having troubles.

Could you please open the file com.esotericsoftware.spine.urp-shaders/Shaders/2D/Spine-SkeletonLit-URP-2D.shader and check if you see this code in line 115:

#if UNITY_VERSION < 202120
return half4(CombinedShapeLightShared(half4(main.rgb, 1), mask, i.lightingUV).rgb, main.a);
#else
SurfaceData2D surfaceData;
InputData2D inputData;
surfaceData.albedo = main.rgb;
surfaceData.alpha = 1;
surfaceData.mask = mask;
inputData.uv = i.uv;
inputData.lightingUV = i.lightingUV;
return half4(CombinedShapeLightShared(surfaceData, inputData).rgb, main.a);
#endif

If you do not see this code in line 115, then something with updating the UPM package has failed updating the necessary files.

If you see this code, you could try changing

#if UNITY_VERSION < 202120

to

#if 0

This will then always use the suitable code branch for Unity 2020.2.

If this also has no effect, then I assume that it is another shader that is used, so please check if you don't have two versions of the same package or two versions of the same Spine-SkeletonLit-URP-2D.shader shader in the project.

回答ありがとうございます！

Unity 内に複数パッケージが取り込まれているようなことは確認できませんでした。
Spine Unity Download: spine unity 4.0
などから再度ダウンロードし、

Spine パッケージそのものも削除してから、再度 Import Package してみましたが、
やはり解消されませんでした。
URP shaders も同様に試してみましたが、変化ありませんでした。

手動でエラーの出ているところにコード記述すれば、なんとか回避できることがわかりましたので、
それで対応していくことにします。

ありがとうございました！

[Harald]

ご返信、および追加情報をお寄せいただきありがとうございます。

このような状況で観察された動作は実に奇妙であり、 ＃if UNITY_VERSION <202120チェックが期待どおりに機能していないように見えます。 それでも、それに応じてコードを変更することで問題を解決できると聞いてうれしいです。 ご連絡ありがとうございました！

Thanks for getting back to us and for the additional information.

Under these circumstances your observed behaviour is indeed strange, it seems as if the #if UNITY_VERSION < 202120 check does not work as expected. Nevertheless glad to hear that you could resolve the problem by modifying the code accordingly. Thanks for letting us know.

Hey guys, I'm updating my project from Unity 2020.2 to 2021.2. Getting the same error but in Spine-Sprite-StandardPass-URP-2D.hlsl (when using the URP/2D/Spine/Sprite shader, with the latest Spine URP shaders)

Shader error in 'Universal Render Pipeline/2D/Spine/Sprite': 'CombinedShapeLightShared': cannot implicitly convert from 'const half4' to 'struct SurfaceData2D' at /Users/james/PlasticSCM Workspaces/Perennial Order/Packages/com.esotericsoftware.spine.urp-shaders-4.0-2019.1/Shaders/2D/Include/Spine-Sprite-StandardPass-URP-2D.hlsl(95) (on d3d11)

Using you guys' code from this post (minus the UNITY_VERSION stuff), I changed this line:

half4 pixel = half4(CombinedShapeLightShared(half4(main.rgb, 1), mask, input.lightingUV).rgb, main.a);

to this:

SurfaceData2D surfaceData;
InputData2D inputData;
surfaceData.albedo = main.rgb;
surfaceData.alpha = 1;
surfaceData.mask = mask;
inputData.uv = input.texcoord;
inputData.lightingUV = input.lightingUV;
half4 pixel = half4(CombinedShapeLightShared(surfaceData, inputData).rgb, main.a);

So I think the only difference between you guys' code above was changing "i" to "input", and changing what was "i.uv" to "input.texcoord". Was kinda guessing with the "texcoord" there, but I think its correct (referencing TEXCOORD0)

Seems to be working!

Edit: Going to link to this other post I made, in case these two things are related: Issue with URP/2D/Spine/Sprite normalmaps in Unity 2021.2

[Luke]

Glad to hear things seem to be working! If you need any other help, just let us know.

[Harald]

Sorry for the late reply. Thanks as always @Jamez0r for sharing your insights, and sorry for the troubles! We will have a look at both issues very soon and get back to you as soon as we have a fix to offer.

Both issues have just been fixed for 4.0 and 4.1-beta, see the forum posting here on the other thread:

Thanks for reporting!
