Getting started from scratch

Package has customized prefabs: ARGround  & ARDirectionalLight.
So just use them for your scene & enjoy.

1. Create New Unity Project with Unity 2019.1.12.
2. Download and import AR Shadow into Unity.
3. Go to Edit > Project Settings > Quality.
4. Choose Default Quality Level for a target platform.
   1. Shadow Projection = Close Fit.
   2. Shadow Distance = 400.
5. Create New Scene.
6. Create Plane (ARGround prefab).
   1. Place plane on the marker (a bit higher) if you use marker AR like Vuforia. If you use markerless AR (e.g. AR Camera GYRO) then place the plane on your origin so you can see the shadows.
   2. Resize plane for all your active area of game action.
   3. Attach ARShadow material with ARShadowSurface shader (AR/ARShadowSurface) to the Plane.
      1. Cutout = 1.
7. Create Direction Light (ARDirectionalLight prefab).
   
   1. Intensity = 1.5 or 1.0.
   2. Shadow Type = Soft Shadows.
      1. Strength = 0.323.
      2. Bias = 0.13.
      3. Normal Bias = 0.
      4. Near Plane = 0.9.
8. Press Play and see the AR shadows from objects.

Why don’t Shadows work?

1. The common issue is Point 4. Users sometimes just select the quality level in Unity Editor and don’t set it as default. That’s why you can see Shadows in Unity Editor & don’t see on mobile.
2. In your own scene, you could put own plane (i.e. AR Marker) or object at the same Y level with a plane for shadows. Try to raise the plane for shadows a bit.
3. See Video Instruction below carefully.
