Differences Between Modes

The four creation buttons are built from two separate decisions: volume type and creation method. Knowing which decision matters for your shot makes the addon easier to use.

Cube vs From Faces

Point	Cube	From Faces
Preparation	No special face setup required.	Requires Object Mode, two mesh objects, one selected quad face on each.
Selection order	Not relevant.	Important: first selected object = source (A), second selected object = target (B).
Placement	Created at the 3D Cursor.	Built between two selected faces, from the first selected object (A, source) to the second selected object (B, target).
Fade Direction control	Visible.	Hidden because the object is locked to A → B.
Typical use	Fast placement and look development.	Geometry-driven, scene-anchored volume creation.

Light Volume vs Real Fog

Point	Light Volume	Real Fog
Shader logic	Emission-based volume.	Principled Volume.
Main control	Emission Strength.	Fog Density.
Typical look	Stylized beams, light shafts, graphic atmospherics.	Localized fog, haze, and more realistic atmosphere. Real Fog is not emissive, so scene lighting is needed to reveal it clearly.
Performance	Usually faster.	Usually heavier but more realistic.
