How do I get blurred reflections working in UberPOV? I had it working a 
few years go, but have since forgotten how. Thanks.

You only need to add roughness into the reflection block such as :

reflection{0.9 metallic roughness 0.001}
or
reflection{1 fresnel roughness 0.001}
or
reflection{0.8 roughness 0.001}
or
reflection{0.1, 1 roughness 0.001}

Normally, you also want to add specular highlights with the same 
roughness amount.

Thanks! What do I use in the header?

One of my old scenes uses this:

#version unofficial patch 3.71;
#patch 0.99;

But I don't know if that's up-to-date.

I have this:

#version unofficial patch 3.71;
#patch "upov-reflection-roughness" 0.9;

How do I set the roughness of a specular highlight?
Is there a `specular {}` block?

What would the correct way to update the following be?


#local ldrawChromeFin=finish {
  brilliance 6
  diffuse 0.7
  metallic
  specular 0.80
  roughness 1/120
  reflection 0.8
};



Do reflection and specular each have their own blocks containing a 
roughness parameter?


#local ldrawChromeFin=finish {
  brilliance 6
  diffuse 0.7
  metallic
  specular {0.80 roughness 1/120}
  reflection {0.8 roughness 1/120}
};

Oh? I had not been aware of that. Good to know; thanks.

Ignore the `metallic` keyword there since I overlooked it too.

finish{
	diffuse 0.1
	ambient 0
	reflection{1 fresnel roughness 0.001 conserve_energy}
	specular 0.7
	roughness 0.001
   }

It have been around like that for almost for ever...
