because they have mod menu's that bypass the normal checks. They're still modding the game, hence, modders.

They get away with it because new menus get developed faster than Rockstar can shut them down. Now they've managed to manipulate the games code to the point where they can find any lobby that you as an individual are playing, and either join you, or pull you out and put you in their lobby, they're pretty much untouchable.

It sounds like you are just saving your documents as the default psd file that photoshop, and only photoshop, can read. Save as a png and it will work. You simply drag and drop the png file into the openiv ytd and openiv will do the dds conversion for you

As I say, thats all I did and it worked. Now that the new scripthook is out I had a bit of work to get my old mods working properly, but if you don't have that much installed then copying the new update.rpf accross will work fine.

I did nothing more than add the mptuner and patchday25ng lines to the dlclist in my mods folder.

Almost correct, you can skip step 2 entirely, you don't need the folders in your mods folder for them to work. As long as the mods dlclist has been updated they will work

I have simply replaced the GTAV.exe with my backed up version and have added the two new dlclist lines and its all working fine in my SP game now. Only thing missing is the wheels because the Track section doesn't exist in trainers yet

Have patience. Its usually around a week for the updated version to drop, depending on how much in the game has been changed.

likely your graphics settings then. ENB relies on DirectX 11 and high/ultra graphics to work properly

Depth of Field and one other option, I forget which return to 'false' on game launch regardless of what the settings looked like when you save them. All other settings are retained when you press save at the top of the menu

Simply looking at another vehicles meta files will be a massive help.

In short, for a working modkit, you need to define a modkit name in the carvariations.meta, which must be matched in the carcols.meta, and a valid modkit ID (<1024) used.

From there its just a case of adding the parts as xml <Item>'s, again, you're best looking at an existing vehicle to get an idea of how it works.
