Iceberg
This shader was build to easily create large landscapes with just one click.
Fully procedural shader for creating realistic icebergs.
The whole shader is packed into a small node group with only the most important settings shown, so that it's not confusing.
This shader is using microdisplacement, so the only thing You have to do is to apply it on a cube or plane with adaptive subdivison and that's it.
You can apply it on anything, even suzanne.
This product contains a test scene to experiment with it. I recommend using an HDRI to fully appreciate this shader.
Created in blender 2.82, should work with any 2.8 version, won't work with older (2.79) versions.
Includes HDRI from https://hdrihaven.com/.
