Fabric and Leather don't seem to work.

These materials are really nice! That said, using 2019.3.f4 and upgrading to HDRP 7.1.7, the leather and fabric examples don't work quite right on a 2016 Macbook Pro. They show up as black, regardless of which color leather or fabric I select.

The All Materials scene showed a whole bunch of black spheres, which I thought was odd. Switching to the Inidivdual scene showed that the bumps and normals show up for Fabric and Leather, but switching to a new material looks exactly the same. Seems to be an issue with the colors not updating. Using the wood examples, those immediately change colors when swapping out materials as I would expect.

You probably need to put the Diffusion Profiles of Leather and Fabric in the HDRenderPipelineAsset Material section.

Same here!!!!!!
even when I added the profiles, it doesn't

This worked for me on MacOS Mojave:

1. Upgrade project to Unity 2020.1.10f1
2. Upgrade HD Render Pipeline in package manager to Version 9.0.0-preview.54.

Now all the subsurface/iridescence features work in shadergraph, and the materials don't look black.
