RockyIcy Materials - Elite Dangerous Odyssey

Hello Everyone !!
Here is a small part of the RockyIcy materials I have created for the game Elite Dangerous Odyssey.
All of them have been done with the software Designer but most of the one shown here are a blend of my own work and some modifications of Scans.
I have used and modified some Heightmaps of Rock Scans of the software Bridge (UE4) to fasten my workflow and then allow me to create way more materials. The simple Gravel / Scree visible in my blended materials are also from UE4 Scan Library.

As for the Arctic Renders, I didn't found useful to show the Dirty Variances and small iterations created as they don't bring massive interest.
