Riding Dirty
[h2]Hey everyone! [/h2]
Cars in the Car Rental Simulator are meant to be used, and when they are, they get dirty. Keeping vehicles in good condition is an important part of running your business, which is why we’ve been putting a lot of work into how dirt builds up on cars over time.
Getting this right is surprisingly important. The way vehicles collect dirt and grime plays a significant role in the overall atmosphere of the game, helping to make the world feel believable and lived-in.
In the screenshots below, you can see some of the iterations we went through while developing the dirt system.
Our first attempt focused on simply generating dirt on the vehicle surface. It provided us with a basic foundation and helped us test how the system would behave on different vehicles.

The next iteration pushed things much further visually. The effect was quite strong! Sometimes closer to heavy mud than realistic road dirt, but it served an important purpose. It made the dirt easier to see during testing and allowed us to validate other connected systems more quickly.

The current version more accurately represents the dirt you would see on a real vehicle. We’ve been refining the dirt shader, enhancing how textures blend and exposing parameters that allow us to control features such as the size and intensity of dirt patches. This provides us with greater flexibility when adjusting how vehicles get dirty in various situations.



We’re continuing to refine the system so that dirt feels natural and believable across different vehicles and conditions.
Let us know what you think, and we’ll see you in the next devlog!

PS. Don’t forget to add the upcoming free slice Car Rental Simulator: Prologue - Early Days to your wishlist!
