有轮廓功能,但它需要是一个单独的着色器/材质,因为URP只允许一个渲染通道。该着色器可以在材质中选择为"Universal Render Pipeline/Spine/Outline/Skeleton-OutlineOnly"

你可以通过 "RenderExistingMesh "示例组件看到它在示例场景中的使用。
Packages/Spine Universal RP Shaders/Examples/Outline Shaders URP

也有其他方法在对象上添加额外的渲染通道,请看这里的视频(可惜有点长)。

There is outline functionality, but it needs to be a separate shader / material, because URP only allows a single render pass. The shader can be selected in the Material as "Universal Render Pipeline/Spine/Outline/Skeleton-OutlineOnly".

You can see it in use in the example scene via the RenderExistingMesh example component:
Packages/Spine Universal RP Shaders/Examples/Outline Shaders URP.

There are also alternative ways of adding additional render passes at objects, please see this video here (it is a bit long unfortunately):

其实是URP是支持多pass的,第二个pass需要添加 "LightMode" = "SRPDefaultUnlit", 我已经弄出来了,但是spine shader有很多参数需要更改编辑器,希望官方搞定。上传了附件 替换官方的 Spine-Sprite-URP-2D.shader

感谢您提供的信息,似乎最新版本的URP for Unity 2020.2已添加了此渲染过程,或者在此之前未对其进行记录。

如果它也适用于以前的URP版本,我们将进行一些测试,否则我们将需要为这些较新的多遍URP版本提供其他的URP Spine着色器软件包版本。

由于针对Spine 4.0进行了大量的改编工作,因此我们需要一些时间才能使用此功能。 同时,请仅使用您的着色器版本。
-----
Thanks for the info, it seems that the latest versions of URP for Unity 2020.2 have added this render pass, or they have not documented it before that.

We will perform some tests if it also works with previous versions of URP, otherwise we will need to offer an additional URP Spine shader package version for these newer multi-pass URP versions.

Due to a lot of work on adaptations for Spine 4.0 it will however take some time until we get to this feature. In the meantime please simply use your version of the shader.

感谢您的信息。 然后,似乎文档只是缺少此信息。 您能否也让我们知道您正在使用哪个版本的Unity'URP'软件包?

Thanks for the information. Then it seems that the documentation was just lacking this information. Could you please also let us know which version of Unity's URP package you are using?

抱歉,您的回复很晚,感谢您提供的信息!

我只是注意到在我以前的帖子中缺少问题单的URL:
https://github.com/EsotericSoftware/spine-runtimes/issues/1824
实施该功能后,我们会通知您。
-----
Sorry for the late reply and thanks for the information!

I just noticed that the url to the issue ticket was missing in my previous postings:
https://github.com/EsotericSoftware/spine-runtimes/issues/1824
We will let you know once the feature is implemented.
