Getting Started With Custom ERLC Liveries
Custom liveries in Emergency Response: Liberty County let you replace the default paint jobs on police cars, fire trucks, and ambulances with your own designs. It is not built into the base game as a simple menu option. You need to work with the game files or use external livery editors that other players have built over the years. I spent about three months figuring out how to do this cleanly before I stopped reinstalling broken texture packs and actually got it right. The short version is that ERLC stores vehicle textures as .dds files inside the Roblox extraction folder, and changing them requires a specific workflow. Do not just drop a PNG into the folder and hope for the best. It will not work, and your game may crash on startup.
Unlock Your Fleets Identity Create Custom Erlc Liveries With Precision And Purpose
This is the whole point of doing it. A fleet identity means every unit in your roleplay group looks like it belongs together. Generic cop cars from the default game do not convey that. Custom liveries do, but only if they are applied consistently and at the right resolution. First, you need to extract the original vehicle textures from Roblox. You can use a tool like Universal Roblox Extractor or the RobloxStudioBin files if you have the developer tools installed. Once you have the folder structure for the ERLC vehicles, look for the directories labeled "vehicle," "cars," or similar. Inside, you will find the diffuse maps and normal maps for each car model. The textures are in DDS format. That means you need a DDS editor or a converter that supports that format. Adobe Photoshop with the NVIDIA Texture Tools plugin will open them, but it is slow and heavy. I use GIMP with the QTexTools plugin instead. It is free, lighter, and handles most DDS files fine. If a file has a compressed BC3 or BC7 format, GIMP may struggle. In that case, use a converter like NVIDIA NVTT to unpack it to a standard PNG, edit it, then repack it back to DDS with the same compression settings.
When you edit the livery, keep the UV mapping in mind. The default ERLC textures are laid out for specific car models like the Chevy Tahoe, Ford Interceptor, and similar. If you place text or a logo, make sure it lines up with the panel gaps and door seams. I learned this the hard way after spending two hours designing a banner across the side of a cruiser only to realize it was stretched weirdly because I had edited the wrong texture file. The Tahoe uses a different UV layout than the Interceptor. Double check which file corresponds to which vehicle before you invest time in a design.

Resolution and File Size Limits
ERLC vehicle textures are typically 1024x1024 or 2048x2048 pixels. Do not go higher than that unless you want the game to choke on loading times. I tested a 4K texture on a single vehicle once and the scene took about forty seconds to load instead of the usual ten. It looked great for maybe five seconds before the LOD system kicked in and the detail vanished anyway. Stick to 2048x2048 max. Most of the game is viewed from medium distance, so going bigger is wasted effort. File size for the DDS matters too. Compress with BC3 for normal maps and BC1 or BC7 for diffuse maps. This keeps the files small enough that the engine does not stutter. A typical diff map ends up around 1.5 to 2 megabytes. Anything over 4MB is probably too heavy for normal play.
Applying the Textures
Once your edited DDS files are ready, you need to put them back into the Roblox cache folder that the game reads from. The path is usually something like %LOCALAPPDATA%\Roblox\versions\version-XXXXXXXXXXXXXXXX under the ERLC asset folders. Make a backup of the original files first. I have crashed the game more times than I can count by overwriting a file I did not fully understand. After you place the new textures, launch ERLC and join a server. The changes should reflect immediately. If they do not, clear the Roblox cache by deleting the temp folder contents and restarting. This is a common issue after updates when the game replaces texture IDs and your old files no longer map correctly.
Common Pitfalls
The biggest problem people run into is texture ID mismatch. Roblox updates sometimes shift the internal references for vehicle parts, which means your custom DDS points to nothing and the game falls back to the default texture. I hit this after the October 2024 update. My entire fleet looked stock again until I re-extracted the files and remapped them to the new paths. It took about an hour to redo everything. Another issue is that some ERLC vehicles use multiple material assignments. A single car model might have separate textures for the body, the light bar, the interior, and the decals. If you only edit the body texture, the light bar will still glow white instead of your department blue. Check the material assignments before you assume your livery is broken. Look for files with names like "lightbar," "siren," or "interior" in the same folder. There is also the matter of multiplayer sync. Custom liveries are client-side only. Other players will see the default textures unless they also have your files installed. This is not a bug. Roblox does not support server-side custom asset injection without using official groups or plugins. If you want your fleet to look unified for everyone, you need to either share your DDS files with your group members or use a group-owned plugin that distributes the assets properly. There are a few community groups that handle this through their own systems, but they require joining the group and often have submission review processes.
Design Workflow
Create your livery designs in a graphics program at the same resolution as the target DDS. I use Krita because it handles large canvases well and exports directly to PNG. Set up a template based on the UV map of the vehicle you are working on. The UV layout tells you exactly where each panel sits, so you can avoid placing important details over seams or areas that get hidden by wheel wells. Keep the color palette limited. ERLC is a daytime-heavy game with bright lighting. Complex gradients and subtle shading do not read well at game distance. Solid colors with clean text and simple shapes perform best. I have seen groups spend weeks on photorealistic liveries that look like mud blobs at fifty studs away. Simple is better. Flat department colors, clear badge placement, and readable unit numbers. That is what works in practice. If you are building a full fleet identity, create a style guide. Define the primary color, secondary color, font, badge placement, and numbering system before you start editing individual vehicles. I wasted about a week last year because two people on my team used slightly different shades of blue and there was no master reference. The fleet looked disjointed even though we were both trying to do the same thing.
Tools and Resources
The main tools you will need are a Roblox extractor, a DDS editor or converter, and a graphics program. The communities around ERLC livery creation are mostly on Discord and the Roblox forums. The main ERLC livery Discord has working channels for troubleshooting texture issues and sharing templates. There is also a GitHub repo called ERLC-Livery-Tools that bundles some of the converters and a sample UV template. It has not been updated in a while but the core files still work for most current versions. Custom liveries cannot change the 3D model of the vehicle. They only replace the surface texture. If you want a different car shape, that requires modding the mesh files, which is a separate and significantly more complex process that breaks easily across updates. Do not confuse the two. Livery work is paint. Model work is geometry. They are completely different pipelines. Also, custom liveries can get wiped during game updates. When the developers push a new version, they sometimes restructure the asset folders or change texture paths. You will need to reapply your edits after each major update. Budget extra time for this. It is not a set-it-and-forget-it thing. My current workflow takes about twenty minutes per vehicle after I know the folder structure, and roughly an hour for a full twelve-vehicle fleet including design and testing.
Group ownership helps stabilize this somewhat. If your fleet is tied to a Roblox group with a plugin that handles livery distribution, the updates are easier to manage. But those systems are not free and they require ongoing maintenance. For smaller groups or solo operators, manual file management is the only real option right now.
