@PsychoNapkin Yes, it's normal if you spawn "HQ" vehicles with no LODs (Levels of Detail). If you want a stable game, make sure that the vehicles you install always have 3-4 LODs and their polycount is not too high.
Take as example the Ford GT 2005 vehicle mod of Aige, its author. Is one of the vehicles available on our site that have full LODs, looks incredibly good and works fine.
If the replacer vehicle doesn't spawns but the vanilla one does, the problem is that the game finds the vanilla vehicle as the most recent version. That can be caused because of the following:
1.- The EMF folder is not being read by the game when you start it. Make 100% sure that you've installed it correctly, following every step, without mistakes of any kind.
2.- The LSSD Charger vehicle that you've mentioned does not work or the files of the vehicle installed are corrupt, which makes the game unable to load it and instead spawns the most recent "police2" files found.
3.- If it still doesn't work and you've verified that's not a mistake with its installation, you still have the chance to try another installation method, similar to EMF. If you want to try this method, I'd suggest you to do a test with the tutorial available first. If you got the tutorial example working, then you should be able to create your own Add-Ons, because you'd have made one!
@katysz the answer is there.. yes scaling a block is a good idea. . but you need to avoid using .yft model and check if a .ydr file if it has only 1 geometry meshed. ( extract to open formats look for a .mesh file open it with notepad++ . .)
(my personal fav! Let's you drive passengers in taxis and other cars to literally hundreds of destinations all around the map and even set fare / kilometer. Highly customizable code, great fun and a chance to earn a few bucks)
Generally, all mods made by Guadmaz, LCBuffalo, I'm Not Mental and Eddlm you can download in the dark! These are some of the guys that make the most interesting and fail proof content.
I am sorry I can't direct you to an army-related combat mod that you seem to be after. Note however, that you can create quite convincing "missions" just with the use of Menyoo's options. If you feel confident with this tool, you can create some great adventures and shootouts with just this tool alone.
I strongly suggest you also check out" Los Santos Police Department: First Responders" and "Los Santos Rescue Division" mods. These are robust and very complex modifications for GTA that allow you to become one of the LS's finest - either a police officer or a firefighter. Not army related, but if you like uniforms... You may as well try these two out.
Install Microsoft .NET Framework 4.5.2 (or higher, so skip this step on Windows 10)
AND Microsoft Visual C++ Redistributable Package for Visual Studio 2013 (x64).
AND Microsoft Visual C++ Redistributable Package for Visual Studio 2015 (x64).
Download and install the latest Script Hook V. Alsways re-do this step after a R* update is pushed.
Download and install Community Script Hook V .NET and copy the ScriptHookVDotNet.asi and ScriptHookVDotNet2.dll in the main game folder
