  Light is too bright!  [DAT]
 
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 (...)

  Re: Light is too bright!
 
(...) They should probably be less bright, you can multiply the whole RGB triple by a constant less than 1: ... 0.4 * <r, g, b> It would also help changing the 'fade_distance' and 'fade_power' to make them not shine so far. Or you could change them (...) (17 years ago, 25-Mar-07, to lugnet.cad.ray)
 
  Re: Light is too bright!
 
(...) Thank you, Anders, I think that should do it. But the thing is, in LDA I try to do everything before running it all trough L3P. Adding post-processing to the steps already involved in LDA is not very appealing to me. And after the most (...) (17 years ago, 25-Mar-07, to lugnet.cad.ray)

  Re: Light is too bright!
 
(...) I notice you're using white as the color for light.dat. Since L3P pays attention to the color of the light, you can use a much darker shade of gray. The following was done with a light inside the trans red brick with a color of 0x02141414 (...) (17 years ago, 25-Mar-07, to lugnet.cad.ray, FTX)
 
  Re: Light is too bright!
 
(...) I just did before I read your post! (Just called it test.dat instead...) And it really works, the problem is POV will not inline the light into the position of SOFLIGHT.DAT but rather <0,0,0> of the POV world. This makes it more complicated, (...)

  Re: Light is too bright!
 
(...) 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 (...) (17 years ago, 26-Mar-07, to lugnet.cad.ray)
