    Vehicle custom liveries - How to + FAQ


    ****** PC Only! ******


    Sorry, custom liveries for consoles (PS4 and XBOX One) aren't available at this moment.



    Install a custom livery

    Just extract and overwrite files under "[your drive]:\[your system]\STEAM\SteamApps\common\pCars\Vehicles\Textures\CustomLiveries"

    You can find amazing liveries in the Download Database: here

    If you wanna request a paintjob you can do so here



    Livery Creation Guide


    What do I need?

    1. Photoshop CS (or higher) or any other software (e.g. GIMP) that can deal with PSD and DDS file types.

    2. If your software does not support DDS files out of the box you need this plugin: http://developer.nvidia.com/nvidia-t...dobe-photoshop

    3. A bit of knowledge how to use Photoshop, GIMP or whatever software you chose.

    4. Official Paint Templates (Download Here)



    How to (Photoshop Guide)

    1. Open the Template PSD file



    2. Do your art in (or closer to) the specific layer



    3. Flatten all layers (better performance when generate the DDS)
    * dont forget to hide the Wireframe layer

    4. Save your DDS in the proper format (see the "Size & File formats" table below)

    5. Overwrite the related custom livery in "[your drive]:\[your system]\STEAM\SteamApps\common\pCars\Vehicles\Textures\CustomLiveries"


    * Template file names don't necessarily correspond to the livery names. Change, if necessary.



    Size & File formats

    FILE NAME RECOMMENDED SIZE* DDS FORMAT VEHICLE PART RELATED TO
    LIVERY_PLAYER 2048x2048 DXT1 Vehicle Main livery
    LIVERY_FRESNEL 1024x1024 DXT1 Vehicle Livery reflections per angle
    LIVERY_SPEC 1024x1024 DXT5 Vehicle Livery specularity and glossyness
    LIVERY_AI 1024x1024 DXT1 Vehicle AI Livery. If AI uses the "Custom Livery"
    PAINT_CHASSIS 256x256 DXT1 Vehicle Chassi and Roll Cage colors
    WHEEL_DIFF 512x512 DXT5 Wheel Wheel livery
    WHEEL_DIFF_BLUR 256x256 DXT5 Wheel Wheel under rotation
    WHEEL_SPEC 256x256 DXT5 Wheel Wheel specularity and glossyness
    WHEEL_SPEC_BLUR 256x256 DXT5 Wheel Wheel specularity and glossyness under rotation

    -> Always all MIP maps

    Set the DDS plugin to "create new mip maps".

    * 4096x4096px liveries are possible
    Your PC performance and memory is the limit.



    FAQ
    by Jan Frischkorn (SMS Vehicle Art Manager)

    Can we just use 1 custom livery per car?
    Yes. Only 1 custom livery per car at moment.

    There is a 3D viewer?
    No. But you can save the DDS while game is running. See the "3D Viewer Alternative" in the "Tip" section of this FAQ.

    Where do I find the custom textures?
    In your pCARS runtime under "[your drive]:\[your system]\STEAM\SteamApps\common\pCars\Vehicles\Textures\CustomLiveries" you will find default custom liveries for all cars.
    They are all white and show a black wireframe.
    Simply replace these textures with your own and choose the "Custom Livery" in the GUI selection.

    Will my liveries be deleted when I uninstall the game or install a new version?
    We've changed the installer to not replace the files if they're already present, or uninstall them if they've been modified from the defaults, so it should be fairly safe.
    But if you blindly delete your whole pCARS folder say, you'll lose them.
    So you better keep the PSD files of your liveries somewhere safe.

    I have problems saving the DDS files. What can I do?
    Save the livery as TGA.
    Then open the TGA and save the DDS from there.
    That will usually always work. Sometimes there are problems saving DDS files from layered PSD files.

    What settings do the liveries need to be saved with?
    You save them as simple "DXT1" DDS with all MIP maps.
    Set the DDS plugin to "create new mip maps".
    The DDS file should be saved as a square image, so if a PSD file is not square (e.g. 4096x6144 pixels), you first need to resize it to 4096x4096 before exporting it to DDS).

    Are metallic effects possible?
    No, only solid paint is possible at the moment.
    The shaders for these effects are too complicated to be externally influenced.
    However, chrome and matte effects are possible. See specular + fresnel maps at the bottom of these FAQ.

    Chrome and Matte Effect
    by Jan Frischkorn (SMS Vehicle Art Manager)


    What can I do with specular maps for liveries?
    Specular maps control the specularity and glossyness of the material.
    In the RGB channels (normal painting area) you can control how much light gets reflected and what colour it reflects.
    Glossy paint materials usually reflect white light, so it would be 255/255/255 white.
    For matte or semigloss paint you would choose a grey tone, something around 160/160/160 works well for matte paint.
    For the blue chrome (see below) you would choose a bright blue colour.
    The alpha channel controls how glossy the material is, i.e. how blurred the emap reflections are.
    Greyscale values: White = glossy (sharp reflections), Black = matte (blurry reflections). 20/20/20 works well for matte paint.
    The darker the alpha channel, the more blurry the reflections get.
    Specular maps have to be saved as DXT5 (with alpha).
    See attached screenshot and livery textures as example!

    What can I do with fresnel maps for liveries?
    Fresnel maps control the fresnel value of the paint material, i.e. the amount of reflections per angle.
    Detailed explanation here: http://www.3drender.com/glossary/fresneleffect.htm
    This is actually the effect that makes paint and glass look realistic.
    With the fresnel map you are able to create chrome paint effect like on the McLaren F1 cars.
    Greyscale values: White = Paint material, Black/Darkgrey = Chrome
    Fresnel maps have to be saved as DXT1 (without alpha).
    See attached screenshot and livery textures as example!

    Tips

    Avoid RGB pure white and pure black
    All bright colous should be 90% brightness maximum, unless you want flourescent neon colours. And pure black can cause transparency issues.
    Best RGB values should be around:

    Color R-G-B
    White 230-230-230
    Black 20-20-20


    3D Viewer Alternative
    You can save your livery DDS file in the livery folder while the game is running.
    ALT+TAB and back to the game. In "My Garage", move one livery left (or right) and back to the Custom Livery to see your updated livery.
    You can rotate it and zoom in/out in the "Take a Photo" area.


    Wireframe over light colors (Photoshop)
    - Duplicate the Wireframe layer (Ctrl+J)
    - Invert the layer colors: Image > Adjustments > Invert (Ctrl+I)
    - Change blend mode to Darken

    How can pure black cause transparency issues? Any examples?

    Could I use an image for part of my livery, for example - Create a livery containing a person on the side of my car? Or a cartoon character?

    I don't believe it affects things in pCARS, but many games in the past used pure black, or a hot pink, to mean 'invisible.' I don't believe pCARS does this, though.

    Absolutely. Just paste it on where you want it in the template.

    How do I load fresnel & spec maps? I can only load one file at a time in the Vehicles/Textures/CustomLiveries folder
