There are two ways.  The first is to move the discs that create the flare
so that they are behind the object.  This is not very realistic, however.

To do this, change the disc_size variable prior to the
  #include "nkflare.inc"
line. This can be achieved by creating a INC file with the line

#declare disc_size=xxxxxx;  // fill in xxx with the distance from the
                            // camera to the discs that create the flare

and then telling moray to include this file.

NKFlare.txt (part of the NKFLare distribution, located in the PovScn folder)
contains some other documentation about more realistic flare hiding.  There are
a few tools included in the distribution that will dim the flare as the light
passes behind an object.  The only objects that work right now are triangles,
planes, and spheres, though.
