Answer 1

Is that what you need? At least it solves "get the picture of what camera covers"

RenderTexture rt = new RenderTexture( size, size, 16 );
Camera.main.targetTexture = rt;
RenderTexture.active = rt ;
Texture2D virtualPhoto = new Texture2D( size, size, TextureFormat.ARGB32, false );
virtualPhoto.ReadPixels( new Rect( 0, 0, size, size ), 0, 0 );
byte[] itemBGBytes = newTexture.EncodeToPNG();
File.WriteAllBytes( Application.dataPath + "/Image.png", itemBGBytes );
AssetDatabase.Refresh();
