Hello,  
In the older versions of phaser3, I was able to do setPipeline in a rectangle. Like folow:  
`

> this.renderer.pipelines.add(‘Audio\_reakt3’, new Audio\_reakt3(this));  
> var shader = this.add.rectangle(200, 200, 400, 100, 0x000000, 0.0);  
> shader.setPipeline(‘Audio\_reakt3’);  
> this.matter.add.gameObject(shader);

Now in the current version of Phaser(3.52.0) give me this error:

> ```
> Uncaught TypeError: Cannot read property 'copyFrom' of undefined
> at RectangleWebGLRenderer
> 
> ```

I found the problem! I changed `Pipelines.TextureTintPipeline` to `Pipelines.GraphicsPipeline`

Is there any way to add glow effect on shapes like rectangles polygons, etc?  
I already added one div element with filter `drop-shadow` but the dom element stays above to my shader rectangle ☹
