Freeze Frame

//Start your project by making a Mesh > Plane
//Set the Mesh's X Rotation to 0
//Using the scale tool align the edges of your mesh with the edges of the preview so that it just covers the screen
//Make a new Material > Diffuse and make its Cull Mode = Front (thins makes it so the texture for the mesh faces away from the camera //rendering it invisible)
//And also apply the new Material to your mesh
//Create a script with the code below
//Finally add a script component to your camera and add the script you just made and set it to Tapped
//Connect the inputs and it should work

//@input Component.Camera camera
//@input Asset.Texture deviceCameraTexture
//@input Component.MeshVisual meshVisual

//Takes a screenshot which we can access with textureCopy
var textureCopy = script.deviceCameraTexture.copyFrame();

//Applies textureCopy to the
script.meshVisual.mainPass.baseTex = textureCopy;

//Sets the Mesh's texture to face the camera
script.meshVisual.mainPass.cullMode = 1;
