Is this URP compatible?

it has issue with URP look like this

Hello, also hoping that this feature can get released on the URP shaders?

I don't see anything mentioned in the post about the URP shaders supporting or not supporting outlines. Is there anything I'm missing?

I found this post in case it helps others. tldr: outlines are not supported in URP.

Issue with urp

I don't understand why the outlines have different widths when I exported 2 characters with the same settings from Spine, and I have identical shaders settings in unity - but the characters have a drastic difference on their outlines. Would be nice if I didn't have to manually work on the outline width for each character.

We have an issue ticket on our roadmap that deals with implementing screen-space constant ouline width:
https://github.com/EsotericSoftware/spine-runtimes/issues/1615

In the current implementation it it is constant in texel space, so the material property will set it to e.g. 3 texels width. So it depends on the resolution of your input attachment images, if e.g. a head.png attachment has twice the resolution at the same display size, the outline will be half as thick using the same 3 texel width.

We also stumbled upon the issue that different spine characters get different outline sizes in our project and we are too far along to change the attachment images for all the characters.

Do you have an estimation of when the issue ticket will be resolved? If it's too far off we will have to continue development without outlines. Or alternatively, can you share the approach you want to take for it? Maybe we can code something ourselves.

Just to be sure: Is changing the Outline width Material property per Material not an option for you?

A potential solution to this is listed in the issue ticket, using ddx/ddy functions:
https://github.com/EsotericSoftware/spine-runtimes/issues/1615
Basically what is needed is calculating the ddx(uvCoords) and ddy(uvCoords) values (which provides how much each fragment changes in UV space) and multiplying this value with the outlineWidth parameter.

Not really as the differences in png size we have are too big, when we scale up the outline width as much as we would need to, we get other problems.

Thanks for pointing us in the right direction, we will try to make that work!

You're welcome, don't hesitate to ask if you should encounter any problems along the way.

Please check out the blog post here:
Blog: Outline shaders for spine-unity
Exporting with more padding allows you to increase the outline width and not clash with nearby regions of the atlas.
If you are using Mesh Attachments as well, you need to make sure that they provide enough space so that the outline fits.

Hello,
So I know this is an old post but I thought It is worth a try.
I am building a character creator for a game I am working on and I am trying to make it so only specific skin parts have an outline.
I tried splitting the skeleton into 3 separate ones and have each one of them outline independently but the outline is also outlining parts inside of my skin and lot only around lt.

Does anyone here know how I might be able to fix this?

I'm afraid we need a bit more information about what you want to achieve and what your project configuration is.

Are you using Universal Render Pipeline? If so, are you using a URP 2D or 3D renderer setup?

Do you want to have an outline-only effect and nothing of the original attachments showing? I'm asking because the screenshot shows only the outline and no non-transparent attachment images.

First of all, thanks so much for the quick response!

I am using the default Unity Pipeline, for models, I am using the MixMatch example skeleton if it helps.

I am looking to have only the outline showing while having the rest of the skin transperent so I can use it to make an outline only around a specific body part by laying it on top of it. The goal is for the player to be able to click a body part to show the Char customization menu for that body part and have the clocked body part glow(or outlined) as a result.

That's good news in this regard, as there are more spine-unity outline shader variants available for it.

Having the outline on top of your hightlighted body parts will make your life harder than it needs to be. While you could do this, you would need to use the provided outline-only shader for it (with enabled Z-Write) as shown in the Spine Examples/Other Examples/Outline Shaders example scene. Requiring enabled Z-Write of the outline shader however will result in a more jagged outline where overlapping parts cut the outline (harsh transition to fully transparent), due to the nature of how the z buffer works. You can see this in the Outline Shaders example scene as well.

As a result, we would rather recommend to use the normal workflow of having the outline behind the highlighted body parts. Is there a reason why you haven't chosen this way, did you run into any problems with this workflow?

Thanks!
I looked all over for spine-unity outline shader variants all over. Do you know where I can find them? I am already using the Zwrite shader.

Are you perhaps using a pretty old version of the spine-unity runtime? Almost all spine-unity shaders provide an Outline toggle property which switches automatically to the outline shader variant. They are located in Spine/Runtime/spine-unity/Shaders/Outline. Also did you check out the example scene I mentioned? The shaders are used in this scene.

Wrong section I know but is it possible to apply this to Phaser 3?

Let's please continue the discussion at this thread over here:
