- Change build settings to Android/mobile
- Delete Main camera and Directional Light
- Window > Package Manager > AR Foundation > Install
- Window > Package Manager > ARCore XD Plugin > Install
- Window > Package Manager > ARkit Xr Plugin > Install
- Rightclick on Hierarchy Window > XR > AR Session origin
- Double click the tiny AR Session origin > look under inspector > tag: MainCamera
- Rightclick on Hierarchy Window > XR > AR Session (coordinates the real world)
- Rightclick on Hierarchy Window > XR > AR Default Plane
- Click on AR Session Origin in Hierarchy > Look in Inspector > Add Component > AR Raycast Manager (checks for floor)
- Click on AR Session Origin in Hierarchy > Look in Inspector > Add Component > AR Plane Manager (allows you to tag and project things)
- Now we want to add a plane prefab, first we create a folder in project called “prefabs”
- Drag the AR Default Plane into the Prefabs folder
- Drag the blue AR Default Prefab into inspector slot for AR Session Origin > plane manager > plane prefab
- Create in project a scripts folder
- Create a new C# script “PlaceOnPlane”
- Drag and drop this script into AR session origin
- Download free asset butterfly
- Double click on FBX
- Double click on Materials
- Select second sphere (blue metallic) butterfly_Albedo select the material in emissions
- Assets > Butterfly Animated > Prefab > left click on butterfly and drag it inside Place On Place Model (inside AR Session Origin)
- Project Settings > Player > Other setting > Identification > Minimum API Level > Set to Android 7.1
- Build and Run
