This tutorial demonstrates how to use the new PCG Grammar in Unreal Engine 5.5 to generate roofs tile by tile. It builds on a previous tutorial about making procedural buildings, enabling the creation of custom, complex buildings quickly. The video goes through each node one by one, explaining all the new nodes in version 5.5.
