Overview
Volume Forge creates localized volumetric objects in Blender. Depending on the mode, the volume behaves either like stylized emitted light or like localized real fog.
Core logic
| Axis | Option 1 | Option 2 | What changes |
|---|---|---|---|
| Volume type | Light Volume | Real Fog | The shader logic used inside the volume material. |
| Creation method | Cube | From Faces | How the volume geometry is created in the scene. |
Light mode
Light mode uses an emission-driven volume. It is usually faster to render and easier to push toward stylized light shafts, beams, or graphic atmospheric effects.
Fog mode
Fog mode uses a Principled Volume. It is generally more realistic, especially for localized haze or fog with believable shadows inside the volume, but it is also more expensive to render. Real Fog is not emissive, so it needs light in the scene to become clearly visible.
Cube vs From Faces
Cube is the fastest way to place a volume. The object is created at the 3D Cursor and can then be moved and scaled like any other mesh. From Faces is more precise: the volume is built between two selected quad faces, and the selection order matters. The first selected object defines the source side of the volume (for example a window), and the second selected object defines the target side (for example the floor). This creates the A → B direction used by the generated volume.
Animation
All exposed controls can be animated directly from the interface. This includes sliders, toggles, vector values, colors, and most enum-based controls through standard Blender keyframing workflows.
