I suppose that can be simulated by using a lower contrast filter (which is 
done by adding Flares_VisualEffect("contrast",.5) to the beginning of the 
scene, right after including "flares_types.inc")

Can see no reason why not.  There are 22 prebuilt lensflares included, and 
if none of those fit your needs, you can always make your own kind out of 10 
kinds of glows, 9 kinds of "rays", 9 kinds of "streaks" and 11 kinds of 
spots.  And if none of those flare-parts look the way you like it, you can 
always make your own.  So in theory, anything's possible.

thanks! :)
