Dynamic lighting in Unreal Engine was achieved through approximations rather than brute force calculations, allowing for real-time effects like torch flickering and shadows.

The introduction of GPUs changed the landscape of game development, but much of Unreal Engine's early development focused on software rendering before real GPUs became available.

The evolution of Unreal Engine from 1 to 5 has been marked by significant performance gains in hardware, allowing for increasingly realistic graphics and dynamic environments, but the biggest limitation remains its single-threaded nature of game simulation, complicating game logic and making multi-thread programming more challenging.

Unreal Engine was initially developed in C, later transitioning to C++ for better performance and maintainability, which was crucial for the game's success.

The future of storytelling in film using Unreal Engine involves moving away from traditional green screens to LED wall panels that display real-time graphics, enhancing the quality of lighting and actor performance.

The development of Unreal Engine involved a collaborative effort from a diverse team, where constant iteration and improvement were key to success.

Unreal Engine transformed the gaming industry by focusing on creating a powerful game engine rather than just individual games, which was a significant bet in 1995.

We're working on Unreal Engine 6 to address core limitations that have persisted throughout the history of Unreal Engine, aiming to provide a better foundation for modern computing needs.

Nanite, a system developed for Unreal Engine 5, represents a significant optimization effort that required a deep understanding of both high-level and low-level hardware capabilities.
