Christoph Werner shows how to create mountains in Blender dynamically using Modifiers.

Blender 2.8 has a modifier feature. The docs list it as “Modifiers are automatic operations that affect an object’s geometry in a non-destructive way. “If you’ve worked with, or seen someone work with something like 3ds Max, then modifiers might be a familiar concept. Modifiers let you operate in a non-destructive way. Check out this tutorial from Christoph Werner who shows how to employ modifiers to create landscape mountains in Blender.

The tutorial covers creating dynamic mountain structures that take their control from different modifiers. The technique in the video can even be procedural too. Modifiers in Blender seem to be already a much more powerful and intuitive system than they ever were in Max
