Under the Hood: Reimagining Legacy Assets

Since the release of Euro Truck Simulator 2 and American Truck Simulator, the processing power of personal computers has made some serious advancements. In turn, we've continually brought updates to both our titles to introduce new technology and techniques, which has allowed us to introduce higher levels of visual fidelity to our content.

One such rework that has been happening over the last couple of years is the 'reimaging of legacy assets', which aims at enhancing the quality and optimization of game models that have started to look outdated and inconsistent with newer additions. The project team consists of two people, Pavel C and Robert P, both of whom we've had the pleasure to talk to about this project to share with you today. We will let them introduce themselves!

"My name is Pavel C. I've been working at SCS Software for about three years as a 3D Graphics Designer, and I am involved in reimagining legacy assets for our title American Truck Simulator and its DLCs."

"My name is Robert P, and I've been working as a 3D Artist at SCS Software for over three years. I've contributed to several DLCs, including Texas, Oklahoma, Nebraska, and Arkansas."

So, what is the goal behind this project? "Our goal is to create models that not only look realistic but are also well-optimized," Robert explains. "Many of the assets, although well-made, have started to show their age—especially those in use for nearly a decade. As technology advances, there’s an increasing demand for optimized assets with higher levels of visual fidelity."

Beginning a project like this can be quite challenging, especially on such a large scale, Pavel adds. "Initially, we faced many challenges as we realized we couldn’t rely on our current tools and technology for this project. We therefore had to take a different approach and develop a new workflow, often involving multiple programs and new techniques. Our focus was on finding the shortest path to the best results."

"The initiative to give our older assets a ‘facelift’ began about two years ago. Since then, we’ve organized the project and started creating newer versions of assets commonly used throughout the game world," Robert shares.

So, what is the process behind reworking older assets, and which programs are involved? "We start by analyzing the current models and planning each rework. Each asset needs to be recreated with high visual fidelity while being optimized for performance," Pavel says. "First, we analyze the assets we have and consider what can be reused." Robert adds, "Though most assets need to be remade from scratch."

The next step is gathering references, which we either handle ourselves or, if the task is large, assign to our Research Department. We then design a new logic for the asset, focusing on how it will be used and how convenient it will be for Map Designers to incorporate. Pavel explains further, "We prioritize based on each DLC’s needs and the current state of existing assets, actively collaborating with other teams to ensure consistency across projects."

"We have a list of assets in need of replacement, with priority given to those required for each new DLC. Many custom depots themed for various industries are being created, and during discussions on populating them, we often identify assets in need of a remake. We work with the Map Designers since they are the ones who will place the assets into the game world. They have valuable insights on which assets are effective and easy
