How do I make custom ACC liveries?
You can read my extensive tutorial here. The short answer is: you need at least image manipulation software such as Adobe Photoshop/Illustrator or a free alternative such as GIMP. You also need to have the willingness to spend time understanding the wireframes and how they line up.
Or you need to use 3D software such as Blender, but that is above my paygrade.
Where can I download custom ACC liveries?
You can find all my custom liveries in this overview post here. I regularly update it to include my newest liveries, so if you like my work you can bookmark this page!
I downloaded a custom livery but it does not show up
If you’ve downloaded a custom livery but it does not show in-game, it could be due to a few reasons:
- If you can’t find the car anywhere in the game make sure the car file (carfilename.json) is in the correct folder. This would be in your Documents folder on your C:\ drive, under Assetto Corsa Competizione, Customs, and Cars.
- If the car is selectable in-game but has no custom livery, make sure the livery files (decals.png and sponsors.png) are in the correct folder. This would be in your Documents folder on your C:\ drive, under Assetto Corsa Competizione, Customs, and Liveries.
If all of those are set correctly but the game still won’t show the custom livery, you need to follow the following steps:
- Make sure the game is closed
- Open the file menuSettings.json in wordpad, you can find this file in your Documents folder on your C:\ drive, under Assetto Corsa Competizione, under Config.
- Find the value “texDDS” and if it is set to ‘1’, change it to ‘0’. You can find texDDS near the bottom of the file.
- Save the file and close it.
- Go into the livery folder (under Customs > Liveries) of the livery you want to add and make sure you delete any files called “decals_0.dds” or “sponsors_0.dds“.
- Start the game and your livery will be there.
My friends can’t see my custom ACC livery
Unfortunately, custom liveries in Assetto Corsa Competizione (ACC) are not officially supported. The only way you can see them is because they are loaded locally. They are not shared through the server. In order for other people to see your livery, they need to have them installed in their custom liveries folders. This means you have to share them.
There are multiple ways you can share your liveries. A good idea would be to create a shared folder on some cloud-hosting service, such as Google Drive.
Can I make different modifications to ACC?
The short answer is “no”. There are some software add-ons that can read ACCs data and provide an enhanced experience, such as ACC Results Companion or ACC Tools. You can also edit some values to change how your driver looks beyond the in-game options, but that is unfortunately it. If you want a fully mod-able experience, try Assetto Corsa (1)!
I have a different question on custom ACC liveries
Feel free to ask your question in the comments below or by sending me an email at contact@felixdicit.com. Once I’ve found the answer to your question, I will add both to this page.

Hi, Thank you for your tutorials and all the information you have shared. I am trying to figure out how to use multiple material types in one livery, i.e. some body panels are matte while others are glossy, but as there is only one decals.json file, it baffles my small mind. Thank you.
Hi Darran!
Fun question! You can use the in-game colors to create a “base” layer. Then, you can make a second layer using the decals.png. As a cherry on top, you can add a third layer, by putting decals on the sponsors.png!
As an example of this, look at the files I made for this livery: https://felixdicit.com/543-ferrari-296-acc-custom-livery/
The white is from the in-game car creator. The matte blue is the decals layer. And all the rest is on the sponsors layer!
Hope this clears things up for you!
I’m trying to make a custom Aston Martin Livery and the decal colors aren’t matching the ones that are right like the sponsors are. And in Substance painter the colors are how they should be. But in game something gets lost in translation and it’s not the right color. The orange that should be the gulf orange doesn’t match the sponsor. It’s pale like an orange yogurt
This could be due to 2 things: the studio lighting in the showroom washing the colors, or the value settings for your colors in the decals.json and sponsor.json files. If it’s the former, you can check this by going into any track and see how it looks like with different lighting. If it’s the latter, you can for instance add 0.05 on the metallic value to make the colour “pop” more.
I have created a livery that shows when I’m on track but it doesn’t appear in the showroom when I am first selecting the car. Why would this happen?
That’s a weird one, I don’t necessarily have an answer for that one. It could be that retracing the texDDS steps might fix your problem.
I have made my livery but it’s not applied to the car correctly. It is as if the png file has been slapped on the car and the individual pieces are not in the right places. Can you help?
Hi Joseph, please make sure you are working in the right template for the right car. Sounds like you might be mixing up between your Porsches?
Just come back to ACC after a while. Trying to upload a new livery using the same steps I have done before, two pngs, two JSONs but when I put the folder name into the car JSON file the car just disappears in game. Never happened before and left me confused.
Are there perhaps spaces in the folder name your are trying to put in?
Hi Felix ! Is there anyway of changing the wheel colour when you do a full custom livery ?
Thanks
Unfortunately, there is not. It’s one of the downsides to going ‘full custom’, hence why nearly all of my liveries use an in-game base livery instead of just the base carbon layer.
Created a new car in ACC and want to upload livery. When I go to the Customs/Car folder, the JSON file is not there. ACC is installed on the E drive but the ACC folder with the setups and stuff is on the C drive. It always worked now it doesnt (did a full reinstall of the PC, not sure if that is the issue)
If the car is visible in-game, it should have a .json file in the /cars folder. If it’s not there, the game might have created the file in a different location. But it should default to your “my documents” folder. Did your reinstall of Windows create a parallel documents folder, perchance?
