The Background Tab is used to define background image and also for Ground Plane materials.
- Click Browse to select an image to use for the background.
- Click Clear to clear the background image.
- Visible - image is visible (will override any sky settings)
- Reflected - image is reflected in windows.
- This determines how the image is projected onto the sky of background.
Create Planar HDRi Image
- Converts a normal image to a HDRi background image.
- See: Planar HDRi Backgrounds
- Clear out Background Image
- Select HDRi Image from disk
Offsets and Scales
- Use the Image Layer Wizard to size and position the background image and set these values.
- for Cylindrical and Spherical Projections.
Maintain Aspect Ratio
- if this is not checked, the background image is stretched to fill the screen.
Adjust Center Line to Horizon
- If checked then the image will be scaled and offset so that the horizontal center line of the image matches the horizon of the current perspective view.
- The image is scaled and positioned so that it still fills the entire background of the rendered image.
- See: Horizon
- Resets Offsets, Scales and Rotation.
- Loads the Background Wizard to easily position and scale the background image.
- See: Background Image for examples.
Ground Plane Settings
- On - turns on the Ground Plane
- Alpha Channel - makes the ground plane transparent, but shows the shadows on the ground.
See: Alpha Channel
- Elevation - set the elevation of the ground plane.
- See: Ground Plane
Ground Plane Material
- From the Background Tab you can define and edit materials for the Ground Plane.
This lets you apply a grass texture for land, or a Procedural Bump Map and reflection to emulate water.
- See: Background Tab
Alpha Transparent Ground Plane
- With an Alpha Transparent Ground Plane, you can save the rendering as an Alpha Transparent image, and the ground plane will be transparent. However, shadows on the ground will be visible. This can be used to place the ground plane image on top of a background image and still see where the shadows would appear. (Of course this works best if you are placing he image on a flat surface.)
