I think I saw how to do this once but can't find it on the forums now (must be using the wrong search terms)
I want to merge a spikey terrain with a flat one so I have the spikes poking through the flat surfave, easily done (see pic).
But how can i make the transition from flat to spikey terrain a lilttle smoother/softer? Almost like there is a build up of sand or earth about the base of the "spikes".
I suspect this is blue node magic but I don't know where to begin ...
