Texture Screen
This filter uses a source object specified by the Map Image parameter to screen the
target. The source object used can be any image, movie, or shape you want.
When this filter is initially applied, Texture Screen behaves as if there were a black
image applied to the Map Image well, which makes the target appear like a washed
out black and white version.
To learn how to add an object to the Map Image well, see “
Parameters in the Inspector
Map Image: An image well that displays a thumbnail of the map chosen to generate
the screen.
Center: Sets the position of the center of the texture screen.
Angle: Sets the angle at which the texture screen is placed.
