Edit a Volume Forge volume — Volume Forge Docs

Selected Volume

Once a valid Volume Forge object is selected, the panel shows a Selected Volume box with the object name, the current mode (Light Volume or Real Fog), and the Viewport Wire toggle. Use this section to confirm that you are editing the correct object.

If no valid volume is selected, the panel only shows the Create area and a No Volume Selected message. If an object is selected but its expected material setup is missing, the panel shows Selected Object Not Ready.

Selected Volume section in the addon panel — The Selected Volume section confirms which object is active and which mode is currently being edited.

Mask & Falloff

This section controls the internal fade and the overall mask of the volume.

Fade Direction — Available on Cube-created objects. It defines the axis along which the internal fade travels through the volume.
Fade Start — Controls where the visible fade of the volume ends.
Invert Fade — Reverses the fade direction without changing the chosen axis.
Fade Interpolation — Controls how soft or sharp the fade transition is between the visible side and the masked side of the volume.
Edge Softness — Softens the falloff near the volume boundaries.

Mask & Falloff section for a Cube volume — Mask & Falloff on a Cube volume, with Fade Direction available.

Mask & Falloff section for a From Faces volume — Mask & Falloff on a From Faces volume, where the source-to-target setup changes which controls are shown.

Look

This section controls the main visual response of the volume.

Emission Strength — Light mode only. Controls how much light is emitted inside the volume. Increasing it makes the light volume read stronger and denser.
Fog Density — Fog mode only. Controls the density of the localized fog volume.
Main Color — The main visible color of the volume.

Look section in Light mode — Look controls in Light mode.

Look section in Real Fog mode — Look controls in Real Fog mode.

Noise

The Noise section shapes variation inside the volume and is essential for beams, broken-up shafts, and more organic fog.

Noise Amount — Overall influence of the noise.
Noise Global Scale — Main scale value of the Noise Texture itself.
Noise Detail, Noise Roughness, Noise Distortion — Standard procedural noise refinements.
Noise Scale — The mapping scale vector. Lowering the Z value is a key technique for stretching the noise along the volume length to produce longer god-ray style streaks.
Noise Location — Moves the noise pattern in 3D space without moving the mesh.
Noise Rotation — Rotates the noise pattern.
Ray Spread — Opens or tightens the internal pattern along the A → B travel of the volume.
Invert Spread — Reverses the direction of the spread effect.
Noise Animation — Animates the W dimension of the noise. A value of 0 keeps it static. Positive and negative values move it in opposite directions.

Noise section in the addon panel — The Noise section groups the controls that shape, scale, animate, and spread the internal pattern.

Noise Scale with emphasis on the Z value — Reducing Noise Scale on Z is the key control for stretching the pattern along the volume length.

Animated noise control in the panel — Animated noise controls can be keyed directly when the dot button is available next to the parameter.

Volume Shape

This section controls the tube-like rounding of the generated mesh.

Enable Tube Bevel — Activates a non-destructive Bevel modifier limited to the relevant edges.
Bevel Weight Direction — Available on Cube-created objects. It changes which axis the bevel edge weighting follows.
Bevel Amount — Width of the bevel.
Bevel Segments — Number of segments used by the bevel.
Clamp Overlap — Helps prevent problematic self-overlap when the bevel becomes too large.

Volume Shape section on a Cube volume — Volume Shape controls on a Cube volume.

Volume Shape section on a From Faces volume — Volume Shape controls on a From Faces volume.

Bevel modifier visible in Blender — The Bevel controls remain non-destructive because the effect is driven by a modifier.

Weighted edges used for the bevel on a From Faces shape — On From Faces volumes, the edges marked with bevel weight are always the edges adjacent to the source face and the target face.

Cube mode only — with Bevel Weight Direction set to Y, the edges marked with bevel weight follow the Y direction. Only Cube-created volumes let you change those weighted edges with the Bevel Weight Direction setting.

Cube mode only — with Bevel Weight Direction set to Z, the edges marked with bevel weight follow the Z direction. Only Cube-created volumes let you change those weighted edges with the Bevel Weight Direction setting.

Advanced Mask

This section exposes the end of the fade and the darker side of the volume mask.

Fade End — Controls where the fade reaches its end position.
Shadow Color — The color used on the darker side of the volume mask.

Together with Fade Start, Main Color, and Invert Fade, this lets you shape how the volume fades from a cleaner visible side to a darker, more masked look.

Advanced Mask section in the addon panel — Advanced Mask controls for refining the internal masking behavior.
