A Note On Render Pipelines

In this tutorial, we briefly discuss why good lighting is important in your 3D mobile application and this project's learning objectives.

Unity for Artists Curricular Framework Resources

Lighting is one of the most important aspects of real-time 3D visuals. It can set the mood, guide interactions, and identify goals and objectives. Lighting can also make or break a user’s experience. A simple model can look better with good lighting techniques while a detailed model can look worse with bad lighting techniques.

Learn about and compare the differences between static and dynamic lighting. 

Explore tricks to convey the visuals you desire — such as how to fake lighting/shadows — while maintaining optimal performance.

Compare different light modes and light types in order to implement the most efficient and accurate lighting for your 3D Scenes.

When you’re creating a mobile application, it’s important that your final product runs smoothly on as many devices as possible. Unity’s Universal Render Pipeline (URP) — a pre-built scriptable render pipeline that is tuned for mobile performance — has a variety of features to help your mobile application be as performant as possible. For more information about the URP, see the Unity documentation.  

In the next tutorial, we’ll explore the different light types and modes available in Unity.
