Method group The Method group lets you choose which coordinate to use on the normals. These controls are the same as those in the Projection Options dialog on page 6416. ■ Tangent (The default.) Project at a tangent to the target object's surface. This is the method to use for objects that both move and deform, such as animated characters. ■ Local XYZ Project using the object's local coordinates. This method can be used for stationary or moving objects, but not for objects that deform: if the object deforms, the projection will appear incorrect at some frames. ■ Screen Project using screen coordinates; that is, flat projection in the Z axis. X is horizontal, increasing in a positive direction to the right; Y is vertical, increasing in a positive direction upward; and Z is perpendicular to the screen, increasing in a positive direction toward the viewer. This method is useful mainly for stationary objects seen only from a single angle; for example, a statue seen through a window. ■ World Project using world coordinates. This is useful mainly for objects that don't move or deform; otherwise, a moving object with world-projected normals will appear to "swim" through the texture. Camera Map Per Pixel Map Material Editor > Maps rollout > Click a Map button. > Material/Map Browser > Camera Map per Pixel The Camera Map Per Pixel map lets you project a map from the direction of a particular camera. It is meant as an aid to 2D matte painting: You can render a scene, adjust the rendering using an image-editing application, then use this adjusted image as a matte that is projected back onto the 3D geometry. TIP Final rendering can be slow. Script-driven network rendering on page 6433 can help improve performance. Camera Map Per Pixel Map | 6035
