2.4.9.7 No_Image, No_Reflection
Syntax:
OBJECT {
[OBJECT_ITEMS...]
no_image
no_reflection
}
These two keywords are very similar in usage and function to the no_shadow keyword, and control an
object's visibility. You can use any combination of the three with your object.
When no_image is used, the object will not be seen by the camera, either directly or through
transparent/refractive objects. However, it will still cast shadows, and show up in reflections (unless no_reflection
and/or no_shadow is used also).
When no_reflection is used, the object will not show up in reflections. It will be seen by the camera
(and through transparent/refractive objects) and cast shadows, unless no_image and/or no_shadow
is used.
Using these three keywords you can produce interesting effects like a sphere casting a rectangular shadow, a cube
that shows up as a cone in mirrors, etc.
