Getting started from scratch

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

  1. Go to Edit > Project Settings > Quality.
  2. Choose Default Quality Level for a target platform.
    1. Shadow Projection = Close Fit.
    2. Shadow Distance = 400.
  3. 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.
  4. Create Direction Light (ARDirectionalLight prefab).
