I change the color of MeshBasicNodeMaterial or LineBasicNodeMaterial, and I already set needsUpdate to true，but the color not update sometimes unless I rotate the scene.

```javascript
    public showBoundaryWithColor(color: THREE.Color) {
        if (this._blinkAnimation) {
            this._blinkAnimation.kill();
            this._blinkAnimation = null;
        }
        
        this.boxMat.color.copy(color);
        this.boxMat.visible = true;
        this.boxMat.opacity = 0.15;

        this.material = this.boxMat;
        this.material.needsUpdate = true;

        this.edgesMaterial.color.copy(color);
        this.edgesMaterial.visible = true;
        this.edgesMaterial.opacity = 1;

        this.edges.material = this.edgesMaterial;
        this.edges.material.needsUpdate = true;
    }

```
