How to change SpotLight shadowCameraNear parameter in THREE.js?

Question

How do I change the shadowCameraNear and shadowCameraFar parameters of SpotLight?

In this demo, I change the shadowCameraNear parameter in the animation loop, but even though console.log() shows the change happened, the shadowCameraVisible helper object shows no change.

Here is the pattern you need to follow if you want to change a light's shadowCamera parameters dynamically.

light.shadowCameraNear += 0.01;

light.shadowCamera.near = light.shadowCameraNear;

light.shadowCamera.updateProjectionMatrix(); // important
