Hey. I created a platform and placed some cubes there.
Cubes setup:
cube.castShadow = true;
Site setup:
world.receiveShadow = true;
Light source setting:
var light = new THREE.PointLight(0xffffff, 1, 10, 2);
light.power = 600;
light.castShadow = shadow\_on;
light.shadow.mapSize.width = 1024;
light.shadow.mapSize.height = 1024;
light.shadow.camera.near = 0.5;
light.shadow.camera.far = 512;
Настройка рендера:
renderer = new THREE.WebGLRenderer({antialias: true});
renderer.shadowMap.enabled = true;
renderer.shadowMap.type = THREE.PCFSoftShadowMap;
This problem appears 🙄

Look into setting `light.shadow.bias` and `light.shadow.normalBias`. `bias = -1e-4` and `normalBias = 1e2` is a reasonable starting place.

**-1e-4** and **1e2**
What are these symbols?
