SU27 TAXI LIGHTS

Taxi lights dont seem to be working on the su27 in latest version...other aircraft taxi lights working though :helpsmilie:

It is working with latest version (v1.2.12,35194). It was also working prev. version.

Nope tried it again after repairing dcs ob and gear lights are on but no projection.

The only su27 mods I have is your eng cockpit Devrim?

My mod was installed too, but this bug (if it really exists) has nothing to do with cockpit bug.

I didn't test lights at night though...

Do me a favour Devrim and test them at night please....as I said, for me the lights are on but no projection on the ground..other aircraft are ok.

Cheers

silly question, but have you checked your control bindings? sometimes updates break them for some people.

I can confirm the same issue using FC3 Su-27 and with or without any mods. DCS World updated an hour ago.

The key binding is ok as I can see the lights beam/halo effect on the landing gear, but no light effect on the runway/taxiway.

Tested with the start up training mission and a custom training mission with low luminosity (early morning).

No idea what's happening here.

At last some confirmation from someone else

Yes Devrim it really exists:cry:

@ShuRugal....I wouldnt waste time here without doing so first...repeatedly

I noticed it earlier as well. Night mission, the light turned on but no light came out on to the ground.

Perhaps a different behavior on different airfields?

Just tested at Batumi (a simple mission cold start Su-27, default date, 19h or 23h start, no mods at all), no taxi nor landing lights enlight the ground & surrounding indeed (but the light looks alight when looking at it on the front gear, so control is correctly mapped).

Where did you test Devrim & aceviper?

I can verify this as well - Su-27 lights don't reflect off the ground, F-15C lights do. Tested at the VA server, both aircraft in Sochi. Su-27 on the apron, F-15C in a hangar.

Hmm srated this singplayer mission BaseDefence or smthing like that. No Gear Light projection at all

verified, no effect on surface.

and is it ok landing gears can be deployed, retracted on the ground? i hit g button by mistake and my front gear retracted so that my nose has been burried in the ronway

Previously, I tested it in daylight, not at night. It seems I got Aceviper wrong and I checked only gear lights, not projection on surface.

Now, I confirm the bug. At night, the ground is not illuminated. It's like twilight zone... :)

Two beta updates in the meantime and not fixed. :(

Same problem to me, no lights on the ground.

Taxi lights dont work on Su-27. Lights are on but there is no beam.

not only taxi light but landing lights too

omg i see all the necessary connectors have been removed from the model :doh:

wtf..I was complaining about this issue here But nobody seemed to be affected/interessted

LoL Lizzard this isnt a thread popularity contest...I defer to your earlier bug report which I hadnt seen.You have the sharp eyes of a reptile!

Su 27 landing and taxi lights don't illuminate the ground, although they are visible in external model. Can confirm this.

Yup. Experiencing exactly the same issue.

Tried to update video drivers just in case - no visible changes.

Fix for landing and taxi lights bug in Su-27

For those who still suffer from the bug in Su-27 related to landing and taxi lights - here's the fix working in the latest 1.2.14 update available at the moment.

Go to [your DCS World installation folder]\Scripts\Aircrafts\_Common and open Lights.lua file. You have 2 options.

• Find "-- 3 spots" comment in the file, line 69 if you haven't modified the file before. Put this string somewhere before "};" symbol. I put it before Su-33 line:
  

[ Su_27]        ={{5.501, -0.675, -0.002} ,{    5.439, -0.318, 0.121        } ,{ 5.4, -0.234, -0.154}},

• Than find this block of code further down below (should be starting at line 263 or so):
  

lights_prototypes[su_27]               = {[indent]         typename = "collection",
       lights = {
           [WOLALIGHT_STROBES]            = {},--must be collection
           [WOLALIGHT_SPOTS]              = {typename = "collection",
                                           lights = {{typename  = "argumentlight" ,argument  = 209},
                                                     {typename  = "argumentlight" ,argument  = 208}}
                                          },
           [WOLALIGHT_NAVLIGHTS]          = nav_lights_default,
           [WOLALIGHT_FORMATION_LIGHTS] = formation_lights_default,
       }
}[/indent]

lights_prototypes[su_27]               = default_lights_plane(Su_27)

The second option (shorter and simpler):

lights_prototypes[su_27]               = {[indent]         typename = "collection",
       lights = {
           [WOLALIGHT_STROBES]            = {},--must be collection
           [WOLALIGHT_SPOTS]              = {typename = "collection",
                                           lights = {{typename  = "argumentlight" ,argument  = 209},
                                                     {typename  = "argumentlight" ,argument  = 208}}
                                          },
           [WOLALIGHT_NAVLIGHTS]          = nav_lights_default,
           [WOLALIGHT_FORMATION_LIGHTS] = formation_lights_default,
       }
}[/indent]

lights_prototypes[su_27]               = default_lights_plane(Su_33)

Description of the bug. It seems to be Su-27 lights aren't described correctly in the Lights.lua configuration file. If I understand correctly, ED is trying to implement better taxi/landing lights, nav lights and so on for Su-27. You can see the description of A-10C lights for instance or Mi-8. Although the proposed solution works perfectly fine there's the third way to eliminate the bug.

This block of code:

lights_prototypes[su_27]               = {
       typename = "collection",
       lights = {
           [WOLALIGHT_STROBES]            = {},--must be collection
           [WOLALIGHT_SPOTS]              = {typename = "collection",
                                           lights = {{typename  = "argumentlight" ,argument  = 209},
                                                     {typename  = "argumentlight" ,argument  = 208}}
                                          },
           [WOLALIGHT_NAVLIGHTS]          = nav_lights_default,
           [WOLALIGHT_FORMATION_LIGHTS] = formation_lights_default,
       }
}

should be replaced with this:

lights_prototypes[su_27]               = {
       typename = "collection",
       lights = {
           [WOLALIGHT_STROBES]            = {},--must be collection
           [WOLALIGHT_SPOTS]              = {typename = "collection",
                                            lights = {{typename =  "spotlight",    [b][color=Red]connector = "RESERV_SPOT_PTR",[/color][/b]    argument = 209},
                                                      {typename =  "spotlight",    [b][color=Red]connector = "RESERV_SPOT_PTR_2",[/color][/b]    argument = 208}}
                                          },
           [WOLALIGHT_NAVLIGHTS]          = nav_lights_default,
           [WOLALIGHT_FORMATION_LIGHTS] = formation_lights_default,
       }
}

The new portion of code is marked with red color. I borrowed it from Mi-8 code. But this solution isn't that good since it gives weird additional lighting in the cockpit as if you were switching the cockpit lights on (while it's actually off). The thing is it doesn't give you any difference in visual effect of external illumination compared to first and second solutions at all. Obviously, there's something about arguments in the lights description code - we need to know the exact meaning of those in order to implement it correctly. Which is much easier for ED since they know their stuff better. That's why I'm using the solution No.1 so far.

P. S. Of course, you better preserve your original Lights.lua file before you do any modifications. Either make a backup or use JSGME. I use JSGME to keep the original file structure intact.

P. P. S. For those of you who are lazy enough :) I attach my modified Lights.lua file.

Lights.lua

Impressive work PowerBroker :)

I think I'll just wait for the fix by ED (I guess you understood correctly indeed).

For those who still suffer from the bug in Su-27 related to landing and taxi lights - here's the fix working in the latest 1.2.14 update available at the moment.

nice try, however as i wrote earlier:

all the necessary connectors have been removed from the model :doh:

so, earlier connectors were attached to the nose gear strut, with gear up/down animation the light direction changed when the strut was moving

moreover the connector directions were wrong, taxi light must be illuminate forward, 2*landing light must be illuminate downward and slightly to left-side
