Are there any efficient ways to add the moon as a light source? Also, the light level should never drop to 0,0,0 because of starlight (I'll not mention Olber's paradox here;) I seem to recall that our eyes effectively become more monochromatic as the light level drops. Something to do with rods & cones, I think. One type is more sensitive to different colours and the other type is more sensitive to light levels (I can't remember which way aound it is). The upshot is that when light levels are high enough for the colour sensitive cells to work we see a colour 'image' but as the light level drops we see a more monochromatic image because the colour cells stop working and we only get input from the light sensitive ones. Is there a way of dynamically adjusting the colour saturation, or achieving a similar effect? Also, also, if you could possibly find a way of introducing up-lighting when passing over towns/built-up/etc. from the texture types... that would be sooo cool;) ;) LeeE _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
