The issue was raised on this forum thread : https://forum.unity.com/threads/metal-on-subsurface.1531339

Steps to reproduce:

1. In a HDRP project, create a new Stack-Lit shadergraph

2. Set the shader to support Subsurface Scattering in the graph inspector

3. Assign a metalic mask texture (or noise, or whatever) to the metalic output

4. Assign a diffusion profile to the diffusion profile output

5. Assign the material (either the default one from the shadergraph, or a new material using the shader) to an object

Actual results: No metallic effect is visible on the object

Expected results: While I can understand that it is not possible to mix SSS and metalic, it should at least be possible to disable SSS and have metalic visible when the metalic value goes over a certain threshold.
