#10.5.2su4 release notea software
Lumen implements efficient Software Ray Tracing, allowing for global illumination and reflections to run on a wide range of video cards, while supporting Hardware Ray Tracing for high-end visuals. The system renders diffuse interreflection with infinite bounces and indirect specular reflections, highlighting even the most minute details within expansive, elaborate environments.Īrtists and designers are no longer tied to static scenes with precomputed lighting baked into textures-a huge time saving when you can see the results of changes right in the editor without needing to rebuild lighting, or to set up lightmap UVs for individual Static Meshes. Changing the angle of the sun, turning on a flashlight, opening an exterior door, or even blowing up a wall will cause a change to indirect lighting and reflections. Lumen is a fully dynamic global illumination and reflections solution that immediately reacts to scene and light changes, offering artists and designers the ability to create more dynamic scenes with greater realism.
