This sample is free to download and provides the opportunity to dive under the hood of the technology used in today’s most advanced interactive digital showrooms. It enables you to explore all the different components of Unreal Engine that make up the project, from the Blueprints used to the Variant Manager. Importantly, there’s no custom software and no C++ coding used—virtually everything you see can be achieved in regular, vanilla Unreal Engine 4.26. Our goal with this project is to demonstrate how the standard feature set that exists in Unreal Engine can be used to achieve stunning results. All materials come from the Automotive Materials Pack and the project uses existing lighting scenarios, along with in-engine features like ray tracing, Sequencer, Volumetric Cloud system, and Control Rig

You can customize your car with different paint colors, and change features that you’d expect to find in a dealership configurator, such as the wheels, trims, seats, interiors, and other standard variables. When you’re done, you can render out a short commercial using the Movie Render Queue.
