■ Display the image in the camera viewport. Use Views menu > Viewport
Background.
■ Orbit the camera until the perspective of the scene roughly matches that
of the still image.
■ Adjust the camera's perspective to fine-tune the perspective match.
■ Move the camera or target to position the scene against the background.
If you raise or lower the camera, raise or lower the target by an equal amount,
in order to keep them level and maintain the horizon.
Hot
A hot material is one that is instanced in both the scene and the Material
Editor. When you get a material from an object, that material is hot. Any
changes you make to the hot material are reflected in the scene wherever that
material is applied.
To edit a material without changing the scene, you can get the hot material
from an object, then make a copy of it. The term for the copied material is
cool on page 7747 .
White triangular tabs in each corner of the Material Editor
sample slots on
page 5208 show that the materials in those slots are hot.
In the Material Editor, the only time you need to select an object is when
you're assigning a material to an object. When you're adjusting a material,
object selection doesn't matter.
