PropMotion

Overview

PropMotion is a Claude Code skill for making 3D objects move well in SwiftUI apps using SceneKit. It is for the single 3D moment an app sometimes needs, such as a product on a pedestal or a badge that rolls in, rather than games or AR. It collects knowledge that is scattered or undocumented, such as shadow and shader compilation pitfalls.

Features

• Sets up a transparent SCNView stage over your SwiftUI layout with camera, lights and a shadow rig
• Designs motion with cue sheets and baked keyframes
• Handles grabs, throws, trackball spins and haptics
• Guidance on realistic materials
• One SKILL.md plus eighteen reference files loaded when needed
