Each PortalScene can contain any number of child nodes and content, and each PortalScene can have its own background texture. If a PortalScene is set to passable, users are able to walk through the Portal into the PortalScene.\n\nThe following example shows how to create a simple Portal that transports you from your current location to a beach-like resort.\n[block:code]\n{\n \"codes\": [\n {\n \"code\": \"// Add a Light so the ship door portal entrance will be visible\\nOmniLight light = new OmniLight();\\nlight.setColor(Color.WHITE);\\nlight.setPosition(new Vector(0, 1, -4 ));\\nscene.getRootNode().addLight(light);\\n\\n// Load a model representing the ship door\\nObject3D shipDoorModel = new Object3D();\\nshipDoorModel.loadModel(Uri.parse(\\\"file:///android_asset/portal_ship.vrx\\\"), Object3D.Type.FBX, null);\\n\\n// Create a Portal out of the ship door\\nPortal portal = new Portal();\\nportal.addChildNode(shipDoorModel);\\nportal.setScale(new Vector(0.5, 0.5, 0.5));\\n\\n// Create a PortalScene that uses the Portal as an entrance.\\nPortalScene portalScene = new PortalScene();\\nportalScene.setPosition(new Vector(0, 0, -5));\\nportalScene.setPortalEntrance(portal);\\n\\n// Add a 'beach' background for the Portal scene\\nfinal Bitmap beachBackground = getBitmapFromAssets(\\\"beach.jpg\\\");\\nfinal Texture beachTexture = new Texture(beachBackground, Texture.Format.RGBA8, true, false);\\nportalScene.setBackgroundTexture(beachTexture);\\n\\nscene.getRootNode().addChildNode(portalScene);\",\n \"language\": \"java\"\n }\n ]\n}\n[/block]\nTo try this example, you can download the beach 360 photo and portal ship door assets [here](http://dq0qxqxzgyp27.cloudfront.net/virocore/readme_example_assets/portal_example_assets.zip).
