    That demonstration is not something that was developed by Epic even though it's using Unreal Engine 4. As pointed out on our own GDC Presentation for ray tracing features, it's a future initiative that we will work on.
    Please push it to the forefront of tasks...

    I haven't seen any RTX light baking demos at all, the only references to it is ideas for doing it in the future

    Ray tracing has only been in the engine since April, and it's still experimental. So no

    Supposedly there's some private prototyping going on with a new lightmap baker using raytracing. But there's nothing public yet afaik.

    Exactly, that and it's really low level, so it's lightning fast.

    Missed this one somehow, thanks man. Lol indeed. Looks nice, hopefully it will be integrated into the engine by Epics, not as a separate branch on the Github maintained by enthusiasts. Now, I have to go check the VXGI2 is building properly...

    Hi all!

    Apparently Epic will share some info at SIGGRAPH 2018:

    "Join Juan Canada and François Antoine in exploring the latest exciting ray tracing advancements in Unreal Engine. We’ll break down the roadmap of our new path-tracer and progressive lightmapper, then reveal our latest real-time ray-traced showcase"
