how to make an object look wet in Eevee? (blender 2.8.3 at least) I was going to answer here How do I make an object look wet? as it does not specify the rendering engine, but it was closed...
I created a UV Sphere.
Then I used sculpt to make some irregularities to let it shine.
There is 2 lights above, one to the left, other to the right.
Using Principled BSDF (w/o texture).
at Principled BSDF:
Metallic is not what I want, doesnt look wet anyway.
Changing Specular doesnt help, the shine is not sharp/thin.
For a very simple, fast and easy to do effect, I just had to:

In edit mesh mode I used &quot;face/shade smooth&quot;, so no need to subdivide the mesh (wouldnt be enough anyway).
change Roughness to about 0.125, even w/o a texture.

It looks good.
Not sure tho if it could cause trouble later to try to apply other effects (not that I am trying to).
It is only visible in &quot;Viewport shading&quot; &quot;render preview&quot; mode.
