I am working with the trial version of City Engine and have been attempting to learn through the tutorials provided. In this tutorial video #1 CityEngine Tutorial: Essential Skills - YouTube the tutorial creates a new project and scene which I follow, however when he does so, there is a grid that appears which I cannot seem to get to work on my computer. Also, when he uses "Grow Street" the streets show up, however when I complete the task, it shows the streets were created, however they do not appear in the viewport. Any ideas what is wrong? Is it a setting issue? Thanks for the help!
