Fog3D
Depth-based 3D atmosphere
Adds atmospheric fog to a Fusion 3D scene with color, density behavior and near/far distance controls.
Fog3D
DaVinci Resolve · Fusion
Fog3D creates depth cues by progressively blending scene objects into a fog color according to their distance from the camera.
Overview
What Fog3D does
Fog3D creates depth cues by progressively blending scene objects into a fog color according to their distance from the camera.
Mental model
Think of it as atmosphere between the camera and the objects: distant geometry disappears into the fog before nearby geometry does.
Common uses
Add atmospheric depth to 3D scenes
Fade distant geometry
Create stylized haze
Separate foreground and background objects

Inspector
Important parameters
Start with these controls before reaching for more complicated workarounds.
Controls / Show Fog In View
Shows Fog In View in the Viewer for setup or diagnostics.
Viewer guides do not normally change the rendered image unless the control explicitly says otherwise.
Controls / Color
Sets the color of the 3D fog.
Controls / Red
Adjusts the red channel.
Use channel-specific controls when the operation should not affect all components equally.
Controls / Green
Adjusts the green channel.
Use channel-specific controls when the operation should not affect all components equally.
Controls / Blue
Adjusts the blue channel.
Use channel-specific controls when the operation should not affect all components equally.
Controls / Radial
Enables radial fog behavior instead of purely camera-distance fog.
Controls / Type
Selects the type used by Fog3D.
Controls / Type / Linear
Uses linear fog, with density increasing between the Near and Far distances.
Controls / Type / Exp
Uses exponential fog, so density builds nonlinearly with distance.
Controls / Type / Exp2
Uses a stronger squared-exponential fog response for a denser falloff.
Controls / Fog Distance / Near
Sets the distance from the camera where linear fog begins.
Controls / Fog Distance / Far
Sets the distance at which linear fog reaches its far-end density.
Settings
Standard Fusion node settings for processing, masks, blending and animation.
Practical setup
A reliable workflow
- 1
Build and frame the 3D scene first.
- 2
Insert Fog3D into the scene flow.
- 3
Choose Linear for predictable art direction or exponential modes for denser atmospheric response.
- 4
Set Near/Far while looking through the final Camera3D.
- 5
Match fog color to the intended environment.

Examples
Where this node fits in real work
Depth haze
Farther objects fade softly into a dark-blue atmosphere.

Graphic tunnel
Fog hides distant repeated geometry and makes the tunnel feel deeper.

Troubleshooting
Common mistakes
Setting Near/Far without checking the final camera.
Using a fog color unrelated to the background and creating a visible cutout look.
Making density so high that the whole scene becomes flat.
Trying to use Fog3D as a substitute for lighting.
Production notes
Practical tips
Tune fog after camera framing because depth values depend on the shot.
A little atmosphere is often more effective than heavy fog.
Use fog to simplify distant detail and improve depth readability.
