Auto-Matic is an Editor Utility Blueprint that I developed for Unreal Engine 4. It aims to solve the tedious task of manually placing vehicles by automatically generating them in a random, realistic, and rapid way. Using the UI parameters exposed to the user, a parking lot with thousands of spaces can be realistically filled with vehicles in seconds. The video below demonstrates the different types of looks that can be achieved.
