Add a real-camera-style depth-of-field blur. Focus on the device while the background softens, or rack-focus dynamically across the animation.
Enable DoF
In the property panel for the active device, toggle Depth of Field on. A new section appears with focus and aperture controls.
Controls
- Focus distance — where the camera focuses, in scene units. Larger values focus on objects further from the camera. The device sits at a known distance; the panel shows its current distance for reference.
- Aperture (1–5) — how shallow the depth of field is. 1 is wide aperture (very shallow, strong background blur). 5 is narrow aperture (most of the scene in focus). Real photography terms inverted for usability — bigger number, more sharpness.
- Bokeh shape — round (default), hexagonal, octagonal. Affects out-of-focus highlights.
Presets
The DoF panel exposes three quick presets:
- Off — no DoF.
- Tilt-shift — narrow horizontal strip in focus, top and bottom blurred. Miniature-faking look.
- Bokeh — extreme background blur with round highlights. Product-shot look.
Keyframe DoF
Both focus and aperture are keyframable. The classic rack-focus pull:
- Keyframe at 0%: focus distance on the device, aperture 1 (strong blur on background).
- Keyframe at 100%: focus distance moved back (background sharp, device blurred).
The transition between the two becomes a cinematic rack-focus.
Performance
DoF adds render cost — each frame runs a multi-pass blur. Expect 10–30% slower renders with DoF on. Preview-quality renders are fine, but plan for it in final exports.
