   Hi all!


Is there a way to make the red tail-lights shine a little less brightly? I use the following code, 1 36 -50 -55 108 -1 0 0 0 0 -1 0 -1 0 4073.DAT 1 36 50 -55 108 -1 0 0 0 0 -1 0 -1 0 4073.DAT 1 15 -50 -53 108 1 0 0 0 1 0 0 0 1 light.dat 1 15 50 -53 108 1 0 0 0 1 0 0 0 1 light.dat , and get this result: http://web.telia.com/~u66203131/LDA/spiff05.avi (Spiffcraft by Dan Jassim)

The following is the same scene, except that white (color 15) was used for the light:



This doesn’t completely solve the problem, since the brick in the first example doesn’t look all that lit up. But it’s something to keep in mind.

(...) Wow! Thank you! I didn't know that. I tried some different options, and found that the "black" light (color 0, which isn't really black) surpringly produced the best balance between taillights noticably on and not spreading too much red light (...)

(...) In my 1998 Christmas picture (URL) (go to the end of the page) I hand adjusted the lights (one inside each candle) quite a bit. One important part was the material settings (Color46_t), as the clear L3P parts are much *too* clear. Most of the (...) (18 years ago, 26-Mar-07, to lugnet.cad.ray)
