Update.

HI,

As many of the modders are making cars for the game, i am focusing on the ELS siren lights of gtaV

It is not easy to understand the logic that rockstar has made for the siren lights.

As far as i know for now is:

-The lights are bounded to the mesh pivot.(and not the dummy)
-the lights has a preset direction (no omni/360 degrees)
-the ELS mesh is moving from direction when the light is flickering on that moment.
-the ELS mesh Scale is bigger when the light is flickering.
-the emissive material setting for the lights is not yet known.(and for the first tries i couldn't reproduce this)

If you have information please share it on this topic

Update:
-The mesh scale distance(small off light mesh to rezised bigger on light mesh) is related to the distance between the siren dummy and the mesh. 
if the siren dummy is at the same distance as the mesh, the mesh only resize to its bigger enabled form. but get no position change.
disadvantage of this, the mesh in siren off will be visible.
-The mesh scales with 50% bigger when sirens enabled.(so making the emissive siren mesh 50% smaller then the original, it will be resized to it's original form.)

Update 2/3:
-Siren dummy and pivot points need to be at the same place.

siren 1 =left red cannot rotate light(always the left direction)  Rotate mesh 90 degrees clockwise
siren 2 =front red(light can be rotated. to do this rotate pivot and siren dummy axe)
siren 3 =back red(light can be rotated. to do this rotate pivot and siren dummy axe)
siren 4 =back blue(light can be rotated. to do this rotate pivot and siren dummy axe)
siren 5 =front blue(light can be rotated. to do this rotate pivot and siren dummy axe)
siren 6 =right blue cannot rotate light(always the right direction)  Rotate mesh 90 degrees against clockwise
siren 7 =front red(light can be rotated. to do this rotate pivot and siren dummy axe)
siren 8 =front blue(light can be rotated. to do this rotate pivot and siren dummy axe)
siren 9 =front red(light can be rotated. to do this rotate pivot and siren dummy axe)
siren 10 =front blue(light can be rotated. to do this rotate pivot and siren dummy axe)
siren 11 =back red(light can be rotated. to do this rotate pivot and siren dummy axe)
siren 12 =back red(light can be rotated. to do this rotate pivot and siren dummy axe)
siren 13 =back blue(light can be rotated. to do this rotate pivot and siren dummy axe)
siren 14 =back blue(light can be rotated. to do this rotate pivot and siren dummy axe)
siren 15=back red rotate mesh180 degrees
siren 16=back blue rotate mesh180 degrees
siren 17=front red(light can be rotated. to do this rotate pivot and siren dummy axe)
siren 18=front blue(light can be rotated. to do this rotate pivot and siren dummy axe)
siren 19=front red(light can be rotated. to do this rotate pivot and siren dummy axe)
siren 20=front blue(light can be rotated. to do this rotate pivot and siren dummy axe)

so the best position to have the lightbar mesh is between sirenmesh(no flash) and siren mesh (flash)

Seems interesting.. I wonder if LMS has made any progress. Looks like this is going to take quite a bit of work. I will be jumping into zmod3 tonight.

How in the bloodiest of hell did you manage to put that lightbar on that buffalo!?!?!?!

rewriting

with building. and testing. but that is just easy. the difficult part is to map the els.

For sure bro. I've tried myself to get to the light settings that needs to be "exploited", but that ain't easy at all. Anyway, great job so far.

Still needs some work. The Lighting 'Extras' seem to be a bit too large at the moment. But like Evolution, these things take Time to achieve Greatness.

Messing around

how did you get that patern? :O

These are the light settings from the lifeguard jeep.

F5544, how's it coming with ELS lights so far?

Brilliant. If we only could make them flash all blue for instance...

These are the light settings from the lifeguard jeep.

Indeed, it replaced the whole model actually.
I have no idea what files controls which siren/lights is used by a vehicle.
So of course, if you use the lightbar from the LGUARD (which has no real textures, just flashes/model) with the "settings" (which ones?)
of a normal cop car, it'll do some weird stuff with the models and flash blue and red.

hmm.. the research for now is that the emissive (lights mesh) is 50% smaller in zmod. it expands when the sirens are enabled. i am now looking for the right offsets. but i think that every siren dummy has its own offset.

updated

BTW, if anyone could replace that horrible and ugly halogen lightbar on the ambulance, then that would be great.

Some stuff I've found out is the the 'pivot points' for lightbars should be in the middle of the Z (I think that the right one) aixs and general they use from left to right siren 1-6, and I'm going to test it but I think 15-20 is the rotating lights

Siren 1 & 6 also need to be rotated so that the ' door side' (so left side for 1 and right side for 6) face the front

Also I'm still experimenting with angels but if say  model is at an angel of 20° then the light mesh should be at -20°

I'm still testing a lot of things but this is just what I've found you

 

Now F5544 when you say 'dummy' do mean a literal 'dummy or are you talking about the pivot point

 

EDIT: also when exporting stuff from Zmod 2 to 3 in .3ds a scale of about 950-100% looks best

yes i mean dummy.
no the rotating lights are in a different setup. its in a other file not zmod file.

Hows your charger coming along ? 

everything is done, but i am searching for the tuning parts file. to assign tuning parts.
but there is no information about it.

I recommend you slow down Macgregor's video to see how he makes his lightbar. It is very helpful. Use the video controls at the bottom to slow it down a bit.
