This is a tileable material that was completed about a year and a half ago while still learning SD, I had to update the original graph to expose parameters for user control, optimization of the graph (node clean-up, organization, and navigation points with comments). This oxidized rock was recreated from a reference of photos I take from cool nature stuff every now and then. This material is free for you to grab from my store and is UE4, Unity & Substance Painter ready. Hope you have fun exploring it as I did. All the best!
