A profiling tool gives detailed information about how a game is performing. The Profiler window is a powerful profiling tool that is built into Unity. This tutorial describes what the Profiler window is used for and how to use it to diagnose performance problems in a game or other application.

Once you've discovered a performance problem in your game, how should you go about fixing it? This tutorial discusses some common issues and optimization techniques for scripts, garbage collection, and graphics rendering.

The goal of the Lightweight Rendering Pipeline (LWRP) is to provide optimized performance for developers targeting a broad range of platforms, VR, and games with limited realtime lighting needs. It does this by making some tradeoffs with regard to lighting and shading.

Volumetric Fog is a powerful tool in an environment artist's kit. Volumetric Fog is a wonderful addition to any scene that could use a sense of space, whether it be a dusty town, a gloomy cemetery, or a grand throne room. Most implementations of fog, such as exponential or linear fog, are computed at an object’s surface by the Shader that the surface uses. At most, this is once per pixel. Volumetric fog, on the other hand, is computed at intervals in the empty space in front of the camera, independent of any surface. In this tutorial, you will learn to create and adjust Volumetric Fog.

9-slicing is a 2D technique which allows you to reuse an image at various sizes without needing to prepare multiple assets. It’s often useful to be able to dynamically resize graphic elements in a game or application. In this tutorial, you will learn to create and use the 9-Slicing technique.

Textures are essentially image files used to provide visual detail to the many GameObjects that comprise your Scene. Whether it’s the sleek mahogany of a coffee table or the rough bark of a tree in the forest, Textures play a crucial role in providing character to your objects. Normal maps are a special kind of Texture that provide a sense of surface detail to these objects. In this tutorial, we will use Adobe Photoshop to export a Texture, import it into Unity, generate normal maps, create a simple Material, and apply it to a sphere GameObject.

Scriptable Rendering Pipelines allow developers to write how Unity renders a frame in C#. Developers can use the built-in pipelines, develop their own pipelines, or customize an existing pipeline to meet a project’s needs. In this tutorial, you will learn about the different Scriptable Render Pipelines.

In this tutorial, you will learn how to optimize VR and AR experiences in Unity

In this tutorial, we’ll dive deeper into Unity Cameras with scripts that control their behavior. We’ll start out with a 2D Camera that works from any perspective (in this case, we’ll be using it in an overhead view). Next, we’ll move on to 3D with a Camera that smoothly transitions — with a flick of the mouse scroll wheel — from first-person to third-person and back. This Camera is suitable for games, VR, or architectural walkthroughs, as seen in many modern and classic 3D titles.
