I am trying to create an infinite runner game..what i want to know is how long does a scene will play in the actual game. Also the platform is gonna be skyscrapper rooftops with gaps in between so the player have to jump over all those obstacles, do i need to import individual rooftop assets as individual platforms? I have attached a pre-viz image of the game to-be, this is in landscape mode but i plan on creating the final output in portrait.
