[HDRP 5.13 - 2019.1] SSR doesn't work

I enabled SSR in both the general HDRP Pipeline Asset, in the Default Frame Settings, in the materials, and by adding the SSR post-process in the scene settings.

Not a reflection to be found. As if I never activated the effect.

Am I the only one to whom this happens? Am I missing some other setting to turn on?

… nevermind. Sure enough, I did indeed forget something.

I just had to change the default min smoothness value in the SSR volume settings.
