Hi I want to add an alpha property to my shader from shaderToy but I’m not too sure how to do this.

You need to add needAlphaBlending: true in your options: https://www.babylonjs-playground.com/#EWME8L#32
Yeah. Great. Thank you 
One more thing
The plane is not actually totally invisible. Can I fix this? is it from babylon or from shader?
From the shader, you can try smthg like this : https://www.babylonjs-playground.com/#EWME8L#33
