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.

When exporting USDZ from Blender to Reality Composer Pro (RCP), you need to convert the orientation from Z-up in Blender to Y-up in RCP. You have two options to do the conversion. See the pros and cons of them.

ShaderGraph Nodes in RealityKit
This documentation shows a list of ShaderGraph nodes. ShaderGraph nodes are components for creating shaders provided by RealityKit, one of Apple's frameworks. Developers can create complex materials and visual effects using Reality Composer Pro's node-based material editor, or manipulate them programmatically through the API.

This document summarizes MaterialX Specification v1.38 and MaterialX Supplemental Notes v1.38, and describes the Standard MaterialX Nodes and RealityKit Custom Nodes. It also shows correspondence between MaterialX Standard Nodes and RealityKit implementation.<br><br> Information about RealityKit is based on the visionOS beta. It may change with the release.

Particle System in the Reality Composer Pro
This document shows the overview of the RealityKit Particle System and the preset particles' parameters. The explanation of each parameter is from Apple API documentation.
- Since this information is based on the beta software, the content may be changed when releasing the version 1.0.
