Any good shader add ons....

For Blender please?
i.e any add on that adds normal, specular and diffuse in one go?
Anything like this available please?

Plenty of PBR shaders around on here and probably blendswwp too - just do a search.

if you are prepared to download a pre-release build - version 2.79 includes the new principled shader which has all of that.

I am of course assuming you are talking about Cycles though…

ahhh yes thanks you.

Thank you. Yeah I was reading about this, so this can make almost any material I want and it does normal, specular and diffuse etc
