Really excited for the emissive lighting–does that work like how it did in UE3 or is it a better method? Specifically, in UE3 it looks like it would analyze the surface and then place invisible lights to match the emissive level of the texture. It didn’t give all that great of results.

Interesting, cool to have an update so quickly after the 4.5 one. :slight_smile:

Awesome! I thought we were still a week away from preview time :smiley:

Quick question though, what does “Landscape Split Out” mean?

Thanks guys!

The right click context menu in the blueprint editor has been redone, looks the same, but it should be much better now at giving you more reliable contextually sensitive results. The old version tended to miss a lot of things.

Sweet, emissive lighting will make a lot of people happy. I am also curious about Landscape Split Out, btw.

15

Hey ,

We are still working on the release notes for 4.6, and I honestly don’t have much additional information for the Landscape Split right now. I’ll post back when I get some additional notes.

Is that the VXGI technology from nVidia?

Very interested in the emissive lighting, looking forward to . =)

No, allows you to use emissive textures as lighting–like if you’ve got a computer screen you can have it emit light and shadows into the level. is only for static lighting though. It’s important for oddly shaped light sources.
Before, emissive textures can just glow and not actually emit light into the level.

19

hoping there’s an option to keep emissive lights the way they are.

Any news on progress dealing with bone scaling bugs? i.e. improperly scaled root motion, improperly generated physics assets?

Was really hoping that was on the 4.6 horizon when root motion got updated…
