OD Create VDB assists in the easy creation of VDB Fog volumes or VDB Levelsets (Solids)

Options:

• Type: Defines the type of vdb, Fog Volumes are smoke, Levelsets are solids
• Voxel Size: The size that each voxel takes up (essentially the detail level of the vdb, smaller = more detailed but obviously slower)
• Voxel Offset (can grow the initial vdb in “thickness”) The value is in voxels, so 1.0 would be 1 voxel thickness added or removed
• Add Noise: For Fog Volumes, you can optionally add some simple noise

This tool assists in the basic setup, from which then, you can either jump in the openVDB node editor (for fog volumes) or the vdb levelset replacement plugin nodes.
