you need the door script in the mod description

you need to edit your vehicles.meta <layout> to something that support 5 or more seats, like LAYOUT_STD_STRETCH, stretch use seat_dside_r2 tho, this is the easy way, and you may need to adjust seats position because its a standard layout so the seats are high, if you need low layout seats you have to do your own vehiclelayouts.meta, not an easy task

@Gborge98 It happens when the author of the mod use png or high compressed dds textures, using something like argb 32bpp dds solve the problem, because it is almost lossless, but larger file size, you can fix the color issue replacing the file with 0 saturation and saving with the 32bpp dds type, yet the image already had a bit of quality loss

@Maxdugen same here, even replacing the collisions the camera wont change, must be something else wrong in the model, if I find the cause I'll let you know

@Maxdugen yes in zmodeler and maybe codewalker xml export, but I'm not sure what line to edit, and if its locked you may need permission from the author anyway

@JohnFromGWN yeah its more like a collision config, I made some tests here: https://imgur.com/a/FTEV3kb

first 2 images are chassis_dummy with the same size of the car, then around 2x the scale, same camera, it also affect grass around the vehicle

@Maxdugen the 3rd person camera depends on the chassis_dummy[COL] scale, it is set on zmodeler, you can check if its too big in openiv, open the car model and select "bounds" in the upper menu, the collision box should be the same size of the car, compare with default cars

@SierraT to adjust the rotation use <fPopUpLightRotation value="27" /> this line will be outside of subhandlingdata, just one line above <SubHandlingData>
