Raster,
thank you for your reply, but the problem is still exist.
If I set color2 to "0 0 0" or another value near that (like "15 15 1" etc.),
the RECT is not visible.
The "color" property do nothing.
I think that when calculating the brightness of RECT, color2 plays a
different role than indicated in the documentation.
Moving of the light source does not change the situation
(tested values of -500, -1000, -50000, -500000).
Example file is attached.

color2 is the DIMMEST it can be... this is ambient light. ie "black" or "no
light from light source". if it is 250 as in your example.. u wont even see
it
get dark. you see a bright rect all the time - just SLIGHTLY getting darker
(255 -> 250 and back). set color2 to be 0 0 0 and u'll see it shade.
you ALSO have another problem.. your light source is VERY close to the rect.
light brightness is calculated at the vertices PER vertex. this is the case
because it is gouraud shaded. that means that color is interplated between
the
vertexes. if your light is in the middle of the rect but VERY close to it
(and
it is - just 10 pixels away) then the verticies will be at steep angles to
the
light point and thus dark UNTIL it rotates, then the edges that are not
roated
are lighter as they rotate to face the light and those far in the distance
point further away and thus get dark. try zplane for the pointofview (light
too) as -500 or -1000 and see. :)
