    We have a project with a lot of SSS. It shows up fine everywhere, but on my Mac with a Radeon 560, everything looks fine except SSS objects are black. Tried to reimport it a few times. The HDRP demo proj seems to be ok. Is there anything Im missing to debug this?

    Hi. Our QA get the same version and do the test and the SSS objects works.

    I do'nt have other suggestion than trying to delete your library folder to force a reimport of the project.

    Hello! I've got the exact same issue in a project using Unity 2019.2.13f, HDRP version 6.9.2, and a Mac with a Radeon R9 M295X (it's a few years old but it's the only Mac we've got). Every material works so far except those with subsurface scattering, which show up as though their base color is black; smoothness and alpha clip work normally. Deleting the library folder and reimporting does not fix the issue. Has anyone found a fix?

    Hi, our QA have checked with Catalina and HDRP 7.1.8 / 2019.0.6f1 and we have no issue.
    Have you try to delete your library folder, do you have any packages remaining in your cache? (local cache) that could make that you don't use the correct package or something else?
    Or maybe can you share your project? thanks.

    I'm struggling with the same issue. Macbook Pro - Catalina 10.15.3 - radeon pro 560 - Unity 2019.3.8 - HDRP 7.3.1 - fresh HDRP project. Subsurface scattering turns the material black. I've tweaked every setting I can find and nothing changes the black output.

    Did you ever find a solution to this problem? I'm experiencing the same issue.

    The only way I could ever get it to work consistently was to move my entire project into a new HDRP Sample Project and then, by some trick of extensive trial and error that I haven't been able to pin down since, it started working. It's therefore possible, but difficult. I have also run into the black-materials-on-subsurface-scattering on a Windows machine, and in that case it had something to do with the diffusion profiles not working correctly -- they weren't findable in Assets when setting them in a material via the Inspector (i.e. using the little bullseye icon) until I clicked and dragged them manually from the Project folder to the Inspector. If I try troubleshooting more on the Mac, I'll probably start with the diffusion profiles.

    Hi, our platform engineer have been able to reproduce the issue and fix it. It is related to some kind of weird synchronization issue in low level Mac code. A fix is coming and will be backport to 2019.3, it should fix SSS but other issue that appear on Mac as well with HDRP. should be available in less than a month.

    Any update on this issue? It's been a month since @SebLagarde said the fix was coming. I had this issue today after moving a project from Windows to MacOS, using Unity2020.1.0b8. SSS shaders are very dark and unusable.

    thank you!

    Disabling High Quality under HDRP settings fixed it for me... I'd like a better fix thought.
