What it is
A 34-minute Blender tutorial by Gleb Alexandrov (Creative Shrimp) on micropolygon displacement, also called adaptive subdivision, in Cycles. It shows how to build landscapes, planets and sci-fi patterns from procedural and image textures, and comes from the Space VFX course update.

The secret is thinking about landscapes as layers of displacement, so you can create landscapes out of procedural textures. See thenoise texture? Now imagine it as a heightmap, with the vertices displaced according to its data. T'is the whole principle. To learn more about it, just watch this video by gleb alexandrov: [this video] . There's a part about terrain generation at the end.

You have the fractal system too, but is to expensive for the memory, cause this method manipulated the mesh... But if you're using the displacement modifier, you are manipulating the mesh too. My recomendation is: use microdisplacement with Voronoi texture, to make procedural "crackles", and image texture to make "PBR" crackles. This tutorial is so good, there Alex explain how to do microdisplacement with image texture and how to economize memory. [this video] I hope

Following Gleb Alexandrov's tutorial [this video] I made a cool displacement mountain material with adaptive subdivison and a few noise textures in the displacement output. For another project i need this same mountain model, but as real geometry rather than render-based since I want it 3d-printed. Any way to apply the adaptive subsurf modifier or convert the material nodes into an image-displacement texture?
