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, so 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.
