Hello.
Thank you for your feedback.

Can you please let us know:

• The Unity version you used
• Its HDRP version

Or it will even be better if you can attach your project directly here.

That being said, I'd like to let you know that due to the company reset last year, we at Unity have had to deprioritize the development of the ToonShader package.
Consequently, we are currently unable to implement new features or address existing bugs, although the above info that you provide will be beneficial for discussions with the community.

I'd also like to share that the ToonShader team remains passionate about the project, and is enthusiastic about resuming active development when circumstances allow. I’ll be sure to keep you updated on any progress.

We appreciate your understanding and support.

Sure thing,

Unity 6.000.0.26f1.
This is for HDRP version 17.0.3.

Unity 6.000.0.331f1.
HDRP version 17.0.3.

It only throws error during build.

FYI, I just added defines in UnityToon.shader as a dirty fix.

#ifndef PUNCTUAL_SHADOW_HIGH
    #define PUNCTUAL_SHADOW_HIGH
#endif

#ifndef DIRECTIONAL_SHADOW_HIGH
    #define DIRECTIONAL_SHADOW_HIGH
#endif

#ifndef AREA_SHADOW_HIGH
    #define AREA_SHADOW_HIGH
#endif

Yes it does and I can't build my android project, plus it goes into the uncompiled section of the shader and I can't use it. I have to restart Unity, those define's should already be there, if I am not mistaken, I would have to check again.
