Screen Space Reflection?

Can someone explain to me how I get this on my material and how it works?

It’s handled through post processing, as far as I’m aware you don’t do anything in your materials. You can find the parameters near the bottom of the post process settings.

When enabled through your post-process settings, Screen Space Reflections will be handled by your material parameters. Try setting specular to 1 and roughness to 0.

哈哈~ 你一定是遇到了和我一样的问题 我现在已经解决了!
选择 HIGH or EPIC!
