Hide line from Shadow

[Nik]

In the screenshot notice the dark line at the left edge of the shadow. Is it possible to remove this. It shouldn’t be there.

1. Depends on how that line is created.
2. Depends on how that shadows are created.

[Chaser_Code]

mesh.castShadow=false;

[mjurczyk]

if using shadow maps - but the shadows above look like ContactShadows a little, in which case castShadow probably won’t have much effect - the visibility of mesh would need to be toggled pre- and post- shadow plane rendering.

[Nik]

The default for mesh.castShadow is false, that didn’t fix it.

1. The line is an unwanted artefact.
2. light = new THREE.DirectionalLight();
   light.position.set(1,15,1);
   light.castShadow = true;
   light.shadow.mapSize.width = 256;
   light.shadow.mapSize.height = 256;
   light.shadow.camera.near = 0.5;
   light.shadow.camera.far = 25;
   light.shadow.radius = 7;
   light.shadow.blurSamples = 8;

Genius. Works perfectly.
