handler - Laravel 5.2 - customize error "Whoops, looks like something went wrong" -

how can change error page "whoops, looks went wrong."? want show page 404 inside errors folder handler simple:

public function render($request, exception $e) {     return parent::render($request, $e); } 

i assume you're inside of app/exceptions/handler.php

public function render($request, exception $e) {     return response()->view('errors.custom');  }
