5.1 preview 1 is now available. We’ve made a lot of improvements to Lumen GI and Reflections including:
- Two Sided Foliage shading (gather lighting from behind the leaf, scatter it through)
- Better foliage representation with distance fields, fixes over-occlusion on trees
- Better Surface Cache with Software Ray Tracing, shows up in reflections and emissives
- Less noise in GI, especially when the camera is still, and on the High GI scalability level (60fps console)
- Lumen Reflections on Single Layer Water
- Lumen mirror reflections on the frontmost layer of translucent surfaces if you enable ‘High Quality Translucency Reflections’
And a bunch of other smaller stuff.
Please test out Lumen in 5.1 and let us know what bugs you run into in this thread! The timeline for visual fixes is short. We may not be able to fix all of them but we will certainly investigate
