dc.description.abstracten	Specular reflection calculations are one of the essential tasks in computer graph- ics. Because of the importance of its visual factor and because of the computational complexity of such calculations, a lot of different approaches and optimization tech- niques were proposed and are popular throughout the industry. Despite the pop- ularity of various methods, it is common for game engines to offer only one estab- lished approach for specular calculations. In this work, we discuss various popular specular BRDFs and integrate some of them in Unreal Engine 5 in the form of shad- ing models. That way, we provide users with more than one way to calculate specu- lar highlights. We also include visual and performance cost analyses of the models and elaborate on the results.
