    Background Image in 3D

    To use an image as a background image in your 3D View,for example as a reference when doing a model,see using a Background Image.

    Shows a view inside a sphere, on which the background textures are mapped.

    How colors below are interpreted depends on which kind of Sky is chosen.

    • None Enabled
    • If none of these three buttons is checked, your background will just be plain flat color (using the horizon one).
    • Paper Sky
    • Blend Sky
    • The background color is blended from horizon to zenith. If only this button is pressed,the gradient runs from the bottom to the top of the rendered image regardless of the camera orientation.
    • Real Sky
    • If this option is added, the gradient produced has two transitions, from nadir (same color as zenith)to horizon to zenith; the blending is also dependent on the camera orientation, which makes it more realistic.The horizon color is exactly at the horizon (on the XY plane),and the zenith color is used for points vertically above and below the camera.

    When using a Sun Lamp options for are available in the Lamp tab.

    • Horizon Color
    • The RGB color at the horizon.
    • Zenith Color
    • The RGB color at the zenith (overhead).
    • Ambient Color
    • Ambient Light. See also .

    Instead of a color, or blend of two colors, Blender can use a 2D image which it maps toa very large Box or sphere which encompasses the entire scene,or which it maps to a virtual space around the scene.

    The World textures are accessible in the texture menu(just select World first, then Texture).They are used much like the Materials textures, except for a couple of differences.The textures can be mapped according to:

    Texture Coordinates select menu.

    • Texture Coordinates
      • View
      • The default orientation, aligned with the coordinates of the final render.
      • Global
      • Angular Map
      • Used to wrap a standard hemisphere angular map around the scene in a dome.This can be used for image-based lighting with Ambient Occlusion set to sky color.You will generally need a high dynamic range image (HDRI) angular map.(It will look like a weird spherical image).
      • Sphere
      • Sphere mapping, similar to that of materials.
      • Tube
      • Wrap the rectangular texture around in a cylinder, similar to that of materials.
      • Object
      • Position the texture relative to a specified object's local texture space.

    The texture affects color only, but in four different ways:

    • Blend
    • Makes the Horizon color appear where the texture is non-zero.
    • Horizon
    • Affect the color of the horizon.
    • Zenith Up
    • Affect the zenith color overhead.
    • Zenith Down
