What exactly is an EVDB, and why doesn't Expanse use OpenVDB files directly?
In this tutorial, we'll explore the complete Expanse workflow for Unreal Engine. You'll learn what EVDBs are, how Expanse Volumes, Mediums, and Height Fog Volumes work, how to import your own OpenVDB files, and how to build cinematic volumetric environments using Expanse.
Whether you're creating clouds, smoke, explosions, atmospheric fog, or other volumetric effects, this video will help you understand the concepts behind Expanse—not just which buttons to press.
