I'd like to know how to link-up separate displacements on 2 simple shapes, obviously if I duplicate the first ss then the 2nd takes on the same displacement as the first and goes a bit all over the place, Hope that made sense.
I don't think I understand what you mean. You'd just want to plug the simple shape into the Mask Shader of your Power Fractal displacement, or group all your displacement under a surface layer.
Neither do I.
Merge shader or surface shader - main input and child input.
Sorry it was late when I posted this, anyway the merge shader is doing what I wanted, for now.
Thanks.
