Distant backdrops

A camera-centred environment sphere — mountains, a skyline, or a gradient sky — that sits at the horizon and sweeps as you look around.

The interactive version has full-text search, a table of contents, and light/dark themes.


A backdrop fills the far distance behind your scene — a mountain ridge, a city skyline, a hazy gradient sky. Add one with Create ▸ Backdrop (there's also a Backdrop geometry preset). It's an environment sphere centred on the camera at a fixed world heading: it sits at effective infinity, so turning the camera sweeps across it like a real horizon, while walking around never shifts it. The backdrop isn't clickable in the viewport — select it in the Scene Tree and edit it in the Backdrop section of Properties.

Quick presets

Start from a one-click preset, then tweak: Sky and Distant ridge and Valley haze (gradient washes), or Mountains, City skyline, and Foothills (bundled silhouette cutouts).

Kind

KindWhat it is
GradientA two-color wash — a Top and Bottom color fading into a sky dome.
Solid colorA single flat color band.
Image silhouetteA transparent-sky cutout (mountains, skyline, hills) wrapped seamlessly around the horizon. Pick a bundled one or paste a Custom URL, and Tint it (multiplies — drop it dark for a night skyline).

Placing it

  • Heading — rotate the sphere around world-up (degrees) to aim a feature, like a mountain peak, in a particular direction.
  • Distance — the sphere's radius, scaled to sit inside the camera's far plane.
  • Height — offsets the sphere centre up or down; a negative value sits the horizon band lower in view, which sells the sense of far-off distance.
  • Band size — the vertical thickness of the horizon band. Keep it small and the scenery reads as far away.
  • Opacity — fade the whole backdrop.
Custom silhouettes need a see-through sky A custom image tiles around the band, so author it horizontally seamless (left edge meets right) at roughly 2.2:1, with a transparent sky for the cutout — a JPG (which has no transparency) won't work; use a PNG or an SVG with explicit width/height. Same-origin images always load; a cross-origin URL must send CORS headers.
