Gradient noise on specular shader

[jaivw93]

Hi people,

Just created a shader that was perfect and then my computer crashed and I'm struggling to get back where I was...classic.

Trying to create what I think is a gradient in the specular channel of a glossy material with a noisy roughness map, similar to the rock in image below, however I'm not sure what to set my diffuse to.

Any help much appreciated, and please tell me if I'm going in the complete wrong direction.

Cheers

Hi,
my suggestion is to work on the roughness channel, maybe with tiny bump, instead of the specular channel, that should be driven by a dark gray color
