DYNAMIC LIGHT SYSTEM UPDATE
Online Documentation is available here ( with update 1.1 review video and 1.5 level streaming exemple) Provide tools to optimise Dynamic lighting performancesġ) Added Full Support for OpenWorld and Level Streamingġ) Improved code quality ( less struct copy and array realloc )ģ) Added logs options to allow easier understanding of current system state.We're getting 30 to 60% performance improvement with this system, making them playable on a low end gaming computers (8 years old i7 950 processor and GTX 950 graphic card).Īll that in Epic settings for everything except shadow (high)ĭue to the nature of Lumen, and lights affecting more than their default area, setting up the system may be harder in some casesįor support or any questions, please contact us at you post a comment here, we aren't notified and can't answer you quickly. To give you an idea, we have tested in levels from 4000 to 25 000 actors, with 50 to 500+ dynamic lights, more than half of them casting shadows. The portal visibility check is based on Unreal Engine built in HZB occlusion, so it's extremely fast and efficient performance wise. I am explaining it in detail in this video tutorialĪll the lights, and this include point lights, spot lights and all the lights attached in blueprints inside a zone will be set to visible when: The performance gain will depend on your level layout and number of dynamic lights.Īll you need to do is setup portals and zones. The portal system toggles lights visibility to true only when you can see them, tremendously improving the performance. This tool allows you to get a massive performance boost without any quality loss!
Unreal Engine culling is great, but when it comes to dynamic lights, there is still a lot of improvements that can be made.
