UI Mask not working

[Joe_Siu]

Thanks @Pixie1001 and @Noblauch , confirmed the solution its working in Unity 2023-2.

And for those who was wondering like me, apparently there’s been on on-going thread on this issue:

A way to set the stencil buffer through shader graph?

Well the question is as the title says Is there a way i dont know to set the stencil buffer via the shader graph?
