Hello everyone My question is - how do I access the standard camera in the three js editor? I am trying to make a scene with a portal, in the scene I have two cameras (one inside the cubemap) to project the image into the portal. In the case of a local project, everything works fine for me, but in the case of creating a similar scene in the editor, everything goes down a bad path. It seems to me that the reason is that when you click on PLAY, a new camera is created. I attach the script of the scene below. I hope that a solution will be found! Thank you all for your attention!

var otherCamera;
var portalA, portalB;

//console.log(this.children[3].children[0]);

scene.add(ambientLight);
