This is a huge step forward. Amazing work. Now I just need to spend 10 grand on a new machine. Can't wait till this is fully implemented in 4.22. By then it will be much more optimised for single card machines.

Pardon the pun, but this is unreal.... Great work team! I'm geeking-out about the possibilities for the future. I don't know why my mind is so blown watching this stuff. Maybe I just don't know too much about computer graphics. I couldn't believe that these were cg model stormtroopers and a cg Phasma in a real-time raytrace! Yeah it is using that DGX, but imagine where this will be in a few years. To imagine this on a desktop or even in VR! This is some matrix-level stuff right here.

So are ray-traced reflections going to be available in 4.20? Even as an "experimental"? In my case, I don't even need it to work real-time as I use Unreal to create short-films/cinematics so they are rendered out from Sequencer anyway...

Bit of a late response but to my knowledge they're using indices which basically allows you to have each unique vertex in an array and have the indices say which vertex to render. Lemme try to clear it up; lets say you try to draw a cube, there are 8 unique points in a cube, 6 faces which turn into 12 triangles ( every quad is rendered with two triangles ). You have those 8 points stored in some array and you have your indices tell the renderer what vertex to draw in what order so you save memory (I believe) and it renders faster since you're not repeating vertices which take up computing resources. To show what that might look like ( C++ ) std::vector vertices = { //The array, this is a C++ dynamic array found in the standard library. //Each point is a 3 part vector so they have an X, Y, and Z coord. //These are the coords of the vertices on the rear side of the cube. 1.f, 1.f, 0.f, //Vertex 0 1.f, 0.f, 0.f, // Vertex 1 0.f, 0.f, 0.f, //Vertex 2 0.f, 1.f, 0.f, //Vertex 3 //These are the coords of the vertices on the front side of the cube. 1.f, 1.f, 1.f, //Vertex 4 1.f, 0.f, 1.f, //Vertex 5 0.f, 0.f, 1.f, //Vertex 6 0.f, 1.f, 1.f //Vertex 7 } std::float indices = { //The array that contains the indices //Front face, each number tells which vertex to draw in the array of vertices 4, 5, 6, //Draws vertex 4, then 5, then 6 which makes a triangle, and does the same with 6, 7, and 4 6, 7, 4, //Rear face 0, 1, 2 2, 3, 0 //Right face 4, 0, 3 , //Not sure if this is correct 3, 7, 4 ... // The rest of the indices for each face of the square } I didn't explain it very well and I'm probably very wrong, but you can always search up some articles on how things are rendered. Also the cube example has some complications as it'd be very hard to texture and normal the cube, but that should've helped you understand why there can be more triangles than vertices.

Wait why are they using geometry instead of normals? Is it really that big of a sacrifice in quality? I've never had issues with normals working well for ray tracing.

I believe they said near the beginning of the video that ray tracing to normals won't be implemented for another UE4 version or two (more or less).

Well everyone is creating an API for it and/or allocating hardware for it on the next generation components. So, it seems like it's almost a reality.

Charles Donneaud That was real time redering. You would need 4 Quadro GV100 to do it properly. In a GTX 1060 the time to render the full scene would be several hours, even days.

Hello, I am a video producer for Outer Places (www.outerplaces.com), a science and sci-fi website with over 225,000 Facebook followers. We’re interested in creating a short video story about Unreal Engine. Could I have permission to use this footage? I would shorten it to around 30 seconds, add captions, and credit it appropriately. Thank you for your time! Hannah
