Installation

Requirements

Engine	Unreal Engine 5.5, 5.6, 5.7 or 5.8
Plugin dependency	Niagara (enabled automatically)

Install

Install VDB Studio from Fab into your engine, then open your project and check Edit > Plugins > VDB Studio is enabled. The plugin is listed under the Rendering category and is enabled by default.

Search for VDB Studio (1) and confirm its check box (2) is ticked.

Turn on volume shadows

Unreal's Heterogeneous Volumes cast no shadows until the project allows it. The setting cannot change while the editor runs, so set it now:

Project Settings > Engine > Rendering > Heterogeneous Volumes > Shadow Casting, then restart the editor.

You can also do this later: a volume with shadows disabled shows an Enable Volume Shadows (restart) button in its Details panel.

With the plugin running, the next step is to bring in a volume.
