Welcome to 3D Art and Audio Pipeline, the third course in the Unity Certified Programmer Specialization from Unity Technologies. This course will help you prepare for the Unity Certified Programmer exam, the professional certification for entry to mid-level Unity programmers. Unity is used to create real-time 3D applications for many industries, including video games, automotive, film, training, and more. In this course, you will be challenged to solve realistic Unity programming problems that are aligned to topics covered on the exam. In the fourth course, you will build on the Stealth application started in course 3. As a programmer, you work with artists and art assets, and this course will challenge you with some basic art implementation tasks, as well as with modifying art and audio assets at runtime. For example, you’ll implement a “red alert” mode of the game, where the lighting will change and an alarm will sound. Finally, we’ll review the high level considerations you would face to add networked features to this app, or to adapt it to a Virtual Reality or Augmented Reality platform. This is an intermediate course, intended for people who are ready for their first paying roles as Unity programmers, or enthusiasts who would like to verify their skills against a professional standard. To succeed, you should have at least 1-2 years of experience programming interactive applications in Unity. You should be proficient at programming in the C# language and familiar with Unity's scripting APIs. You should have experience in the full product development lifecycle, from concept to launch (and beyond). And you should understand multi-platform development, including deploying applications to XR (AR and VR) platforms.
