My Fake Stone Shader is Black/Dark

I have no clue what i am doing wrong here but my stones show up black every time and i switched settings back and forth, still they come out black. This is annoying.   ::) Had this happened to anyone else here?

I can provide the clip file of my shader settings if need be.

Alright, i was not to sure because sometimes a problem can be identified just by looking at the visual but only sometimes.

Well for starters you'd be better off controlling your fake stones distribution by having them as children of a surface layer. This way you can specify exactly where you want them and control their colour. You seem to have many surface layers and stone layers that are overlaying each other to an extent that its hard to know what should show up where, and without the terrain you've used it's impossible to say. Try giving your stones bright temporary colours at first to help locate them and check their size etc. then when your happy adjust the colours to suit your scene.
Remember also that the order that you place your shaders greatly affects the final look, layers at the bottom of the list being at the top of the terrain. All I can get from your file are green displacement spikes.

I used to an Alpine Fractal with a height of 4000. I had the stones a lighter color at one point as well but still they would show up black. Using the child layers is something i considered and i do need to do that.

How? or more specifically how do you know it had a max height of 4000? or do you mean you used the default alpine fractal terrain which has a feature scale of 4000? If you did this is not the height of the terrain.

O.K I've stripped your file down to just the 3 stone layers and coloured them red blue and purple. First off they don't show up at all using these colours because your using a power fractal shaders as a children of each stone layer with colours that are nearly black. If you disable the power fractal shaders in each stone layer then the colours of the stones shows through, see pic attached. I'm not clear what colour you want the stones to be, is it the colour specified in the fake stones layer or the colour specified in the power fractal shader. At the moment in your picture it's the power fractal colour that's being displayed.

I wanted to stones medium/dark shades but not as dark as i had them. I always wanted the color to be specified by the power fractal shader. Shoot, i guess i will have to go way lighter then i had them. Thanks for looking into this though.
