Landing Lights (solved)

[gral]

Also I think there is some problems with multiple lights or overlapping lights.

Overlapping of two lights might work when you have one effect per light-cone. I checked this with 737-100 and two landing lights. This worked for me here http://img710.imageshack.us/img710/2803/737overlapping.png. I guess this is a "buffer sorting problem"? Anyway thank you very much for this "simple" and nice effect!

What du you meen with 2 effects. Just duplicate and renaim the effects and use each for only one cone model?

Example with overlapping lightcones of 737-100:

1. Copy fgdata/Effects/light-cone.eff two times to
Aircraft/737-100/Models/effects/
Change names of the effects i.e. to light-cone-left.eff and light-cone-right.eff

2. In Aircraft/737-100/Models/lights change light-cone.xml to "light-cone-left.xml" and "light-cone-right.xml". Example for new light-cone-left.xml:

Code: Select all

<PropertyList>

  <path>light-cone.ac</path>

  <effect>
    <inherits-from>Aircraft/737-100/Models/effects/light-cone-left</inherits-from>
    <object-name>Cone</object-name>
  </effect>
 
 </PropertyList>

light-cone-right.xml:

Code: Select all

<PropertyList>

  <path>light-cone.ac</path>

  <effect>
    <inherits-from>Aircraft/737-100/Models/effects/light-cone-right</inherits-from>
    <object-name>Cone</object-name>
  </effect>
 
 </PropertyList>

3. In Aircraft/737-100/Models/737-100.xml look for left and right wing lightcones and change to the new path

Code: Select all

<!-- Wing light cone left -->
  <model>
    <path>Aircraft/737-100/Models/light/light-cone-left.xml</path>

Code: Select all

<!-- Wing light cone right -->
  <model>
    <path>Aircraft/737-100/Models/light/light-cone-right.xml</path>

The effects use the same light-cone.ac but different effects (and buffers?). Maybe there is a better solution? At least on my card the overlapping works with this change.

Hey Gral,

That definitely seems to work. Here are the results:

Maybe you do not want to have only white objects within the light-cone. You change in the new light-cone-left/right effect:

Code: Select all

      <blend>
        <active>true</active>
        <source>dst-alpha</source>
        <destination>one</destination>
      </blend>

to

Code: Select all

      <blend>
        <active>true</active>
        <source-rgb>dst-color</source-rgb>
        <source>dst-alpha</source>
        <destination>one</destination>
      </blend>

Hi Gral,

The above change you mentioned doesn't look too good here. I mean the cone no more illuminates things, Its just a simple cone with a texture!

Works only at dusk But the lightcone effect is not light at all. I hope for OSG::Light. And shadows.
