Ehey gap!

Sure...Leigh Lights are in TWoS since long time ago.

Good to know! I remember you saying that they caused the game to CTD in certain situations...

Probably...Lot of different things from different mods will still cause CTDs in regular modlists. Not in TWoS though...

Okay, that's what I wanted to know

Not do detract from the work of other modders, but I think I have created a more realistic and better looking Leigh Light model (the nacelle type used under the right wing of Catalinas and Liberators) than the one currently used in TWoS. Are you interested into having it in your megamod?

Wow , that looks great!
Of course. You can upload the files when you're done and I'll test them and try to implement...

Okay, as you know adding new meshes to a GR2 file is not possible with GR2 editor. I am now looking for a stock file with five meshes (respectively for: the nacelle case, the glass dome, the reflector yoke, the reflector itself and the light beam).

If I don't find an appropriate GR2 file, I will import my model in a dat file instead.

One more question, is SH5's dumbed-down aircraft AI handling correctly RADAR data? For a perfect functionality, the Leigh Light should be coupled with a radar sensor, and their sim settings should be fine-tuned to work well with each other

I'm not really an expert on airplanes AI but I do know that it's quite limited (A.K.A. stupid). As far as I know planes with radar work pretty much the same like ships with radar, detect a target and head for it...

Okay, the main point of the Leigh lights was that early British airborne radars, ASV Mk I and Mk II, had a minimum detection range of ca. 1,000 yards (914 m), which meant that at night, when darkness hid the silhouette of surfaced U-boats, ASW aircrews had to guess the exact position of their targets, having to perform semi-blind attacks. This is where our lights come into the picture: as early as March 1941, RAF started trials with few Leigh light protypes fitted aboard Wellington bombers. Tests were satisfactory, but then Air Ministry turned to the older (and not nearly as powerful) Turbinlite lights which were already available in some numbers. Results were poor, but it took some time before the Ministry admitted the error, and reverted to the Leigh lights previously tested.

The first front-line Coastal Command bombers started being equipped with Leigh lights in early summer 1942. On detecting a radar contact, aircrews were instructed to drop their height from 1,500-2,500 to 500 ft (152 m) before they attained a range of 1 mile from their potential target, and to switch on their light at a range of three quarters of mile (ca. 1,400 m), just before loosing their radar signal.

It would be nice if, within the restrictions given by SH5's aircraft AI, we could (more or less) simulate those tactics and the inherent sensor limitations.

Other useful figures that might come in handy while setting up our lights:

 

Aircraft used on
Turret type: Vickers Wellington / Nacelle type: Consolidated Catalina, Consolidated Liberator.

Main lens diameter
Turret type: 24 inch / Nacelle type: 20 inch.

Total weight
Turret type: 1,100 lb (500 kg) / Nacelle type: 870 lb.

Diverging lens
10 deg, either orizontal or vertical (operationally, the vertical diverging lens was most commonly used).

Luminous intensity
Turret type: 50 million candelas, or 20 million candelas with the spreading lens / Nacelle type: 90 million candelas (?), or 17 million candelas with the spreading lens.

Max. effective range
Ca. 2 miles (3,700 m) in standard visibility conditions.

Max. traverse angle
Turret type: 60 deg to port and 180 deg to starboard / Nacelle type: 50 deg to either side.

Max. depression angle
Turret type: ? / Nacelle type: 48 deg.

Max. traverse/elevation speed
Turret type: 40 deg per second / Nacelle type: 5 deg per second.

If your rating goes negative until then, you probably won't receive new sub.
Thanks for the response!

@ Vecko

My Leigh light model is now a GR2 equipment (almost) ready for entering service in TWoS. Can you please send me the following files from the last TWoS release?
  • Zones.cfg
  • files of the aircraft standing in for Catalina and Liberator
  • aircraft sensor files (if modified from stock game)

Thank you

Sorry for late reply gap. These would be the files I think...http://www.mediafire.com/file/6q82u3.../data.rar/file

No problem mate,

out of curiosity, what are those "Bomb_cluster" and "DC_cluster" in the eqp files of the air units you sent me? I don't think they are in stock game?

And one last question: in TWoS, are British bombers equipped with Leigh lights from the beginning of the war, and do you think date settings would be applied in aircraft equipment files?

I'm not sure. I didn't really edited much airplane files. Those are coming from IRAI or who knows which mod or modder...

In eqp files all planes which have Leigh lights are equipped with it from 06/42.

Default New Leigh light

I hope I didn't forget anything, I horrible at packing stuff before release:

https://www.mediafire.com/file/6mjpm..._TWoS.rar/file

@ Vecko please check in game my addon before merging it to TWoS.


The Catalina was missing its light node, so no matter the date it never had any Leigh light. That little blunder is fixed now.

Adjusting beam's parameters and testing their effect in game took to me quite a lot of time:
  • The HaloSize in Skybaron's mod seemed to me a bit excessive. I reduced it by a considerable amount. When the light is pointing straight to the camera it still blinds the observer, hiding the aircraft behind it, but now the glare is better proportionate relative to the small reflector producing it. A welcome side effect of this resizing is that now the halo is not as 'pixelish' as before, though I will admit that the effect could be further improved if only I could located the texture it uses...

  • The Angle parameter is only affecting the size of the light projected on the sea surface, not the width of the visual beam, so I edited both this setting and the beam model to be compatible with a 10-deg spread angle.

  • For Color I used a set of RGB values corresponding to a color temperature of 5200K, typical of carbon arc lamps (but their spectrum is so similar to the one of direct sunlight that I could have used as well plain white 255, 255, 255).

  • Range and Atenuation parameters seem to only affect the luminosity of the area enlightened by the reflector. This is a feature that is neglected in stock game (you can barely see the projection of searchlight's beam on the sea surface), I hope I made a good use of it, without overdoing the effect.

    I hoped I could make the light beam more faint and to have a better transition from full light to darkness, but neither the above parameters, nor material's opacity settings, nor texture's alpha channel seemed to affect beam's length and look, so that is possibly an hardcoded feature.

    Finally I wanted planes to switch on their lights at a range of 914 m from their target as historically correct, but no matter how high or low I set the range parameter, during my tests the Catalina has always fired its light at a range of ca. 800 m (not too dissimilar from the desired range), obtaining a bonus in visual range of ca. 6.5 km. At the end I decided to set this parameter to ca. 3200 m, i.e. the declared effective range of Leigh Lights, (though, measured on the TAI map, the in-game range is twice as long).

My traverse/elevation settings are based on historical specifications and require no further comment.

Before you check my work directly in game, I have just a couple of general remarks:
  • For testing purposes, I commented out leight ligt's start/end date settings in Catalina's eqp file (with those parameters the light didn't show up in game); you should remove the comment marks before merging the mod in TWoS.

  • The main texture I have added to the package is 256x256 pixels. Considered Leigh Light's small size, this should be enough, but should you think that the texture resolution is too poor, the original texture is 2048x2048 pixels.

And finally a few screenshots I took this evening (beware: large image size):

 















Well, that should be all for now

P.S: I didn't perform any ballistic test (getting a round to hit that light would be a matter of luck even for a seasoned gunner), but in theory with a well aimed burst of the 2cm Flak, or with a single round of the 3,7cm SK C/30, one might disable the reflector turning its light off, or rip the whole nacelle away from the attacking aircraft

Great work gap!

Can someone please help me with this question?

Currently magnetic detonator torpedoes need to pass very close under their target to detonate, I think minimum 2meters.

However, they should be much more sensitive. I want to increase that range to 4 meters, but I do not know in which file to look for the sensitivity of the magnetic detonator.

Can somebody please point me in the right direction?
