The fix suggested is to remove the very shader features you would be wanting to use Unity 2021.2+ for.

I'm not going to remove these features from the URP12 shaders. That's an individual choice that I'm not going to force on everyone.

But since removing these features fixes the problem, then it would seem to imply the bug in shader compilation is that internal lighting textures for URP12 (light cookies, shadow maps, light maps, directional light maps, depth normals, etc.) do not share or incorrectly share texture samplers.

So the only option left is to further reduce the texture samplers used in all the shaders.

The skin shader uses 10 samplers with 30 textures. The other shaders use 6-7 samplers and don't trigger this problem? So I'll try and keep the sampler count to at most 6.

It maps everything to the LOD0 skeleton, which is the character level with the highest poly count and should be the main.

In your URP renderer settings (Assets/Settings/URP-XXXXXX-Renderer) there is an option: Transparent Receive Shadows. Is that on? Because it looks like the transparencies are not receiving shadows, and they should.

Amazing, this solved it, thank you so much!

@Victor.Soupday Would it be possible to add a batch feature to the tool? I often need to import a number of characters, all using the same settings, then click Build Materials, then Bake. Would be ideal if I could multi-select characters in the listing on the left, and process them all at once.

Hello Victor,

Thank you for your work!
I am trying to setup wrinkles in Unity HDRP, using the last 1.4.9 version. The material looks well setup, if I change manually the vectors, I can see the wrinkles.
I am trying to setup the automatic system to change the weight in real time, I found a script "winkels manager", but it does not change anything (init is ok, but calueSets stays at 0), how can I setup the manager please? is there some documentation/tutorial about that?

Thanks in advance!

There may be a case where the WrinkleOverallWeight parameter isn't exported in the JSON data. If that's the case the Blend Scale parameter will be 0.0 in the Wrinkle Manager which effectively turns the wrinkles off:

Try setting the Blend Scale parameter to 1.0 in the Wrinkle Manager component.

Hello
I did everything like in the this youtube tutorial, but for some reason my character is missing all textures so everythign is just pink?

Wrong package version for the pipeline (project template) you are using. Is the project Built-in pipeline, URP or HDRP pipeline? There is a version for each as the shaders are incompatible (which makes everything pink).

If you didn't specify a URP or HDRP project template when you created the project then it would most likely be the built-in pipeline.
