TWINMOTION 2023.2 IS FINALLY HERE WITH LUMEN!
What is Lumen and why should you use it?
Lumen is a new feature in Unreal Engine 5.3, the game engine that powers Twinmotion. Lumen is a dynamic global illumination system that simulates how light bounces and reflects off surfaces in the scene. Unlike traditional methods that use precomputed lightmaps or voxel grids, Lumen uses ray tracing to calculate the lighting at each pixel on the screen. This means that Lumen can handle dynamic changes in the scene, such as moving objects, changing the sun's position, or switching materials, without any baking or rebuilding required.
