Figuring out a good lighting setup for AR use in Unity via Universal Render Pipeline.

UG_DESU · Feb 2021

Is anyone here good at lighting setups in Unity?

Trying to learn how to use Universal Render Pipeline and im in a situation where we are developing an AR game and we are looking at ways to help processing power. So naturally it would be wise to look into baked lightmaps. But it looks terrible. Anyone got time to help me?

You might want to check your AO settings in the light baking options. Generally you can achieve very nice looking environments with URP even with low settings. That mostly depends on the artistic way you set up your lighting. I suggest you add HDR Lighting to your scene, this could vastly improve the looks.

Really late to the conversation here, but typically in AR you use dynamic IBLs, generated from the device's rear camera. That along with a good occlusion map would really help improve your models.

How it's done in Apple's ARKit:

Google's ARCore
