Thanks for reporting and sorry for the troubles. I have created an issue ticket here:
https://github.com/EsotericSoftware/spine-runtimes/issues/2173
We will let you know once the URP Forward+ renderer is supported by the Spine URP shaders.

---

Forward+ render path is supported by lit Spine URP shaders (Universal Render Pipeline/Spine/Sprite and Universal Render Pipeline/Spine/Skeleton Lit) on both 4.1 and 4.2-beta branches.

New 4.1 and 4.2-beta Spine URP Shaders UPM packages are available for download here as usual:
spine-unity Download.

Please let us know if this fixes the issues on your end as well. Thanks again for reporting!

After some more testing I still am getting incorrect results.

The blue light isn't lighting anything on Forward+, see screenshot

Can you confirm this is working/not working on your end? I have tried with both 4.1 and 4.2 and still getting incorrect results unfortunately - Any help is appreciated

An additional problem,

When creating a new project with 2022.2.2f1 (unsure if this happens in others) and I try repro this using original steps, using Spine 4.1 or 4.2 I get shader compiler errors when using Forward+ and pink textures

Edit 1 I didn't realise I had to download 4.1 from Git, just checking again now
Edit 2 Sorry I have no idea how to import the updated 4.1 from Git. I found the correct branch and downloaded the directory to zip, and im trying to copy the contents of "spine-unity" (Assets etc) into the root directory of my empty project but I just get >300 errors

Please can you explain how to properly import this updated package or link a normal Unity package for it please, thank you

I'm still having problems with this unfortunately, the Skeleton Lit shader just won't compile with Forward+ Selected.

Unity: 2022.2.2f1
URP: 14.0.4

Btw, I noticed the download page doesn't actually seem to have an updated 4.1 or 4.2 runtime (updated 2023-01-11 for 4.1), its just the URP packages that seem updated, is that correct?

Repro:
1) Create new URP project in 2022.2.2f1
2) Install Spine 4.1 or 4.2 beta from Spine downloads page
3) Install matching URP shaders from downloads page, install via Package Manager
4) Open the "URP 3D Shaders scene" from Examples
5) Set the URP Asset in Project settings
6) Observe that the default Forward renderer seems to work fine
7) ENSURE you change the URP SO renderer to Forward+
8 ) Things might LOOK ok immediately, BUT! The Spine Skeleton Lit shader is actually not compiling properly. Select it from the URP shaders, Spine-SkeletonLit-URP and see the following error

Shader error in 'Universal Render Pipeline/Spine/Skeleton Lit': invalid subscript 'shadowedColor' at /Users/welky/Documents/_UnityProjects/Valor/Packages/com.esotericsoftware.spine.urp-shaders-4.1-2019.1/Shaders/Include/Spine-SkeletonLit-ForwardPass-URP.hlsl(173) (on d3d11)

For your convenience I have also uploaded a repro project just incase. You can download here:
https://www.dropbox.com/s/t95srgqr08xdy30/SpineRepro2022.zip?dl=0

Please can you confirm if its working in a fresh project for you or not working, as I'm really struggling to tell if I'm fundamentally doing something wrong.

Thank you for your time!

Harald

Apologies about the repro project, I have made a new one which includes the package correctly and no library folder

https://www.dropbox.com/s/3xcnjbvqpwvyr88/My%20project%20%286%29.zip?dl=0

Once opened, please navigate to Packages->com.esotericsoftware.spine.urp-shaders-4.1-2019.1->Shaders->Spine-SkeletonLit-URP to see if it has the shadowedColor error

After trying multiple times in fresh project I always get the problem:

Shader error in 'Universal Render Pipeline/Spine/Skeleton Lit': invalid subscript 'shadowedColor' at /Users/welky/Documents/_UnityProjects/Valor/Packages/com.esotericsoftware.spine.urp-shaders-4.1-2019.1/Shaders/Include/Spine-SkeletonLit-ForwardPass-URP.hlsl(173) (on d3d11)

Is there any reason shadowedColor may be missing for me in my environment? Are you using d3d11 like I am according to the error?

Thank you for your time

Harald

Thanks so much Spine Team, seems to be working great now! Really, thanks so much for your efforts and patience with me on this issue. I'm now using Forward+ with Spine and that's amazing! Very happy to take advantage of Forward+ performance!

One minor issue i noticed, for 2D "Orthographic" cameras, spotlights do not work with Forward+ in Game View (works fine in Scene view aslong as 2D isn't selected). Pointlights are fine, but spotlights don't seem to work. It works fine in Perspective view, which is what I'm using for my project, so doesn't affect me - just thought you should know anyway - not sure if it's a Unity problem or not or just an incorrect setting somewhere

Anyway, thanks again!
