Question by ivangarciafilho · Mar 14, 2019 at 01:38 PM · lightingbugoptimizationshadowsculling

Light.layerShadowCullDistances not working

Light.layerShadowCullDistances isn't culling my shadows;

How To Reproduce :

  • Create a new scene;

  • Delete the Directional Light;

  • Create a cube;

  • Put the cube as child of the camera;

  • Set It's Transform.localPosition to 0f,0f,30f;

  • Create a PointLight;

  • Set It as Child of the Camera;

  • Set it's Transform.localPosition to 0f,0f,0f;

  • Set Point light to cast soft shadows;

  • Set point light range do 3000;

  • Set point light intensity to 3000;

  • Set in quality settings shadow distance do 3000;

  • Attach to the light the script below :

using UnityEngine;

 public class CullShadows : MonoBehaviour
 {
    private bool everyFrame;
    public float distance;
 
     private void OnEnable() { if (everyFrame) return; SetShadowCullingDistances(); }
     private void Update() { if (!everyFrame) return; SetShadowCullingDistances(); }
 
     private void SetShadowCullingDistances()
     {
         var layers = new float[32];
         for (int i = 0; i < 32; i++)  { layers[i] = 1f; }
         GetComponent<Light>().layerShadowCullDistances = layers;
     }
 }

  • Press play; There will always have 1 shadow caster at least;
