Asset creation workflow for AR apps

This diagram shows the asset creation workflow for AR apps in iOS / iPadOS / visionOS.

It illustrates very basic tools. You can use other tools such as InstaMAT for material creation, Spline for 3d scene creation, and EmberGen / After Effects for texture creation. You can also use Game Engine's built-in tools. They are not included in this diagram.
