@DS2LightingMod How many rays do you use to update the cache direct light? I read on the Nvidia sharc doc that they used like 4% of the screen paths but I figure this is only for indirect lighting

[Fernando Malaria @FernandoMa27753]

@noinodev Looks amazing! How do you do the final gather per pixel with a 64x64 probe? And what tricks do you use to make it that stable? I saw other implementations and they all break apart when moving the camera or a light

[Fernando Malaria @FernandoMa27753]

@SoftEngineer It looks really good! Are you just propagating between neighboring probes, or is there some ray tracing involved? The indirect shadows seem more detailed than what I’d expect from a sparse volume. Also is this real time gi or precomputation?

[Fernando Malaria @FernandoMa27753]

@SoftEngineer How does a pixel know what probe to sample if you're using a sparse structure?

[Fernando Malaria @FernandoMa27753]

@BoganBits @zeuxcg I suppose it's for meshlet/cluster rendering, where each cluster can only contain a maximum number of 256 triangles

[Fernando Malaria @FernandoMa27753]

@JarkkoPFC What are the dimensions of the big tile reservoir texture and small tile texture? How many pixels of the final render image would there be for each of these tiles? Thanks, tried the game and loved the visuals

[Fernando Malaria @FernandoMa27753]

@Kiiiri7 Nice! Do you have any references for this mapping method? How uniform are the rays? I wonder if you can get hemisphere directions with this

[Fernando Malaria @FernandoMa27753]

@KtAakash @I3DCONF @eric_heitz @PJNarayanan @unity How were the shadows calculated in that kitchen scene? Did you implement your previous paper "Fast Analytic Soft Shadows from Area Lights"?

[Fernando Malaria @FernandoMa27753]

@LincolnMargison @RyanMuoio Do you have an example of this?

[Fernando Malaria @FernandoMa27753]

@reduzio Aside from optimizing occupancy by reducing VGPR usage, what other key factors should I focus on when optimizing shader code? Do you have any specific guidelines or best practices you recommend following when writing shaders?
Also thank you for these threads!

[Fernando Malaria @FernandoMa27753]

@MrTapa @kiaran_ritchie Looks great, what do you mean by using FBIK to avoid clipping?

[Fernando Malaria @FernandoMa27753]

@MZyanide @KostasAAA I thought ReGIR was only used for secondary ray hits outside of the camera. Is it recommended to use it for primary hits like this? The results look really good

[Fernando Malaria @FernandoMa27753]

@Pjbomb2 Woah dude, love seeing your progress! How do you handle dynamic objects? By refitting the acceleration structure? If so how do you manage to avoid the AS quality deteriorating over time?

[Fernando Malaria @FernandoMa27753]

@Pjbomb2 How many rays do you shoot per pixel? Are you doing multiple bounces for indirect lighting?

[Fernando Malaria @FernandoMa27753]

@Pjbomb2 Looking good! What are you doing here? Are you implementing an irradiance cache like the kajiya renderer in github?

[Fernando Malaria @FernandoMa27753]

@reduzio @Mautar555 Sweetl! That sounds really promising

[Fernando Malaria @FernandoMa27753]

@reduzio @MikeFabrowsky Isn't gvdb from nvidia already doing something similar? Remember reading about it
