...as well as the "Halogen-Only" option, which looks good on some of Luxart's models as well as older cars.

There is a 2013 Ford Police Interceptor, with lights, on UndercoverChicken's GPM Page... http://gtapolicemods.com/downloads.php?do=file&id=2180

I also have this issue, I don't remember what I did to fix it last time, so I can't help you out. Hopefully someone else can?

OK then, try... - Reinstalling the Scripthook - Verify game integrity (for Steam versions) (make sure to back-up mods) / Reinstalling the game - Checking the compatibility of the mod with your game version (for example it may not work on 1.0.4.0 if it was designed for 1.0.7.0)

Have you tried re-installing the script?

In the GTA IV Graphics menu, there is a "Vehicle Density" option, which putting to a high value should make more cars spawn.

Hey guys, I'm not sure if an idea similar to this has been posted yet, so... I'm not sure how many of you have watched Skyfall, but I was inspired by the scene in the Underground and I thought of an idea where an explosion occurs in the subway, or by the airport and then firetrucks and ambulances would spawn and some would head to the scene, and you would respond as a first responder to treat casualties and/or collect evidence. Not sure if this would be possible/if people would like it, so let me know your thoughts. Cheers guys

Could you make a LCPD skin for the '06 Charger and '05 Impala based on the Chicago Police, a bit like BxBugs' ?

Guys, I'm sorry to spark all this argument, but I was simply telling LtChuck that their model has a lightbar. I'm sure there will be better models soon, but currently (as far as I know) only theirs has a lightbar. I don't like using their mods either, for all the reasons that have been posted above, but some may feel they are viable options until a decent, original Explorer is released.

Fair enough, I was only telling you that their model included a lightbar.

BritishPoliceMods' Utility has a lightbar and can be downloaded now.

You should get in contact with "HeresOtis" (on YouTube) or "OJDoesIt" (everywhere else) to see if it will run on a Mac. It should! You can download it from GTAPoliceMods

Great job!

The siren should play, but if you mean to get the cars to move out of the way, I don't think that it's possible. I'll let you know if I find a way.

If you've modded the vehicles.ide file to contain, for example, the NRG 900 line for your Police Stockade, the AI won't move as the game is reading the model to be the NRG 900. The siren (should) work as the game is hard-coded to play the cop car effects for the Police Stockade.
