@nico_m__ The foliage is all geometry. Nanite does have masking support as of 5.1, but that path has not been fully optimized yet. We tried a few different foliage variations and just brute-forcing it with more opaque geometry turned out to be the fastest :D

@Stubbesaurus Is nanite for foliage using alpha maps at all? Or is it high-poly leaf models being rendered directly?

Chapter 4 is out and it has some serious upgrades! It is exciting to finally ship Nanite in a real game, along with Lumen, TSR, VSM and many other UE5.1 features. Fitting it all within a 60hz frame on consoles is such an important milestone for the engine epicgames.com/fortnite/en-US…

If you, you know. #unreal Sound on...

Today Lumen Global Illumination and Reflections ship in Fortnite Chapter 4 on next gen consoles and PC. This is a huge milestone for Lumen, as it's the first time we've shipped it in a real game, with foliage, and running at 60fps. epicgames.com/fortnite/en-US…

Yeah, I'm totally sold on Lumen and Nanite. Shipping this in a 60 fps large scale multiplayer game...this is nuts. Just amazing work from the team at Epic.

@SebAaltonen Double that if support for DXIL shader debugging was added. RenderDoc used to be awesome for quickly debugging simple shader issues on PC

Unpopular opinion: I would pay more for RenderDoc.

My Superluminal trial period is over. Time to spend money to make money. Good tools are worth it.

Too often, I find myself wondering, in various contexts, if Enter (or Shift+Enter) is going to be the one that starts a new line or the one that posts an incomplete message to everyone.

Lumen took a lot of exploration to reach shippable state. This ability to focus on a single thing is an awesome perk of working at Epic and I wanted to shed some light on early techniques I worked on with @EpicShaders and which we later discarded: knarkowicz.wordpress.com/2022/08/18/jou…

@mmalex Ages ago, I did this as a quick hack for a demo project where I couldn't be bothered to work out the proper way to do it. It was years later that I realized that I had already stumbled into it by accident.

if you want to pick a 'cosine weighted' direction in a hemisphere above a normal vector n, most code you see around messes with constructing a basis around n (yuck) etc; you can just do normalize(n+z) for some uniform random unit vector z! I love this trick. send tweet.

Together with @EpicShaders and @_pmkelly we are doing an in-depth talk on Lumen at #rtadvances. We'll cover (virtually) how we trace rays, reuse computations, solve the whole indirect lighting path and noise, and scaled all of this to "The Matrix Awakens". #Lumen" target="_blank" rel="nofollow noopener">advances.realtimerendering.com/s2022/index.ht…

@marc_b_reynolds @leonard_coder Yes. The intuition from the dice example also still works for intervals. Adding two random [0, 1] values yields a value in [0, 2]. For that to be >1.9 requires that both inputs are >0.9. So it is clear the probability is <1%, instead of the 5% uniform would give you.

@leonard_coder @Stubbesaurus I shouldn't have been so terse. That it's a special case triangular distribution falls out of en.wikipedia.org/wiki/Inverse_t… . The math of both are real numbers.

Really nice video about uniform distribution of points over a disc. Classic stuff at begin but start to be brain-blasting at 10:34 (at least for me :)). I just learned that random+random has a different distribution than 2*random. youtu.be/4y_nmpv-9lI
