Color veins and cracks

[TheBadger]

Hi,

Anyone got a set up I can follow for making color veins like here: http://www.tmsupply.com/TMSupply/files/03/03633dfd-52a5-4853-afd2-0cd8748e100f.jpg I guess I could just make the color veins smooth for the cracks. But first things first.

Im guessing this will require blue nodes to do right. Need this to be procedural.

Thanks if you can help.

Oh, this is for a shader set up for objects not a terrain if that matters.

Yes, use a voronoi setup, and some small scale warp for the jaggedness. Should be no problem, procedurally.
