Lumen Metals in Reflections

Yeah, the errors have been a lot worse recently, I think since they’re not releasing again until 5.1 (probably the fall unfortunately), they’re iterating a lot faster and tearing up other systems. Strata in particular is utterly changing the material and lighting pipeline, and because of how Nanite’s connected, mesh rendering as well. I’ve gotten it to build, but it’s caused random crashs, bugs and errors, enough that it’s too unstable to work with.

I checked on strata pretty recently, they fixed a bunch of lighting and translucency bugs, and it’s approaching the quality of the old path slowly but surely.

And yes, I can’t really have more than one build at this point: between the city sample’s 110Gb and _Main’s 160gb, a significant chunk of my hard drive is just UE5 experimentation.

Some good development news though:

  • Nanite on masked materials appears to be working great, my last test supported over a million bush instances without breaking a sweat. Haven’t been able to try out WPO, but from the Changelogs support is very good right now.
  • Lumen just got a slew of optimizations and is looking at around 15% better performance over 5.0.
  • It says that translucency in RT reflections was improved, no idea if that means anything for lumen but excited by the prospect.

Basically, rendering is getting a lot more powerful and flexible for 5.1, and most of lumen and Nanite’s weird limitations will be gone. It’s going to be strange, especially being able to go all-out on animated, interactive foliage with basically zero repercussions.
