Dark Souls Lighting Engine

Water render updates in #darksouls3 lighting engine. The water optics are now better simulated using absorption and scattering functions instead of basic colors. Includes a small demo which also shows some SSR fixes as well as refraction updates.

Nice you got it working :). To clarify to ppl, this is the Non-PT build older version

@k_a_r_h_u Ty:). It was shared by Loreciao, forgot to add their name on post

@DS2LightingMod Oh so good

Old dragon slayer arena - path traced, the red carpet reflects nicely on all metals

Performance test on Intel ARC B580. Running in 1440p FSR Quality mode, Thanks to user Novawolf from discord.

This is the shadow guide which is computed during SHARC update pass. After LightBVH importance sampling the selected light emission is used to compute the shadow using (LNoShadows - LShadows). LShadows is available anyways through normal path tracing. The shadow guide is then used during main tracing pass to reduce the hit distance when a "shadow is detect" for that ray. The right image shows the accumulated HitT. Note that this should only be done for a "Diffuse ray path" as for specular path its crucial to use the Hit-Distance to light as is so that NRD can track specular motion and reflections.

WIP : Shadows contact hardening and better Umbra/Penumbra regions. This is done by reducing amount of blur in the spatial passes of the denoiser only where necessary, as if you reduce it everywhere in scene it introduces noise and boiling in indirectly lit dark-areas

@panoskarabelas Obviously 10x engineer with AI, it’s facts

I post technical, scientific, and philosophical stuff, far juicier than this, yet this is what goes viral. What can I say 😄

@GazzDo Should be soon Gazu

@DS2LightingMod Sht looks mega crazy good. Any plan on "release date" or beta stuff ?

Thanks to Vorona for the screenshots

@dark1x Hope you feel better soon , stuff happens that’s all is there to it

I think this video does a good job explaining the viewpoints of the team but I wanted to make sure it was clear that I wasn't feeling up to participate yet thus not in the video. I will share my own thoughts soon but my opinions largely mirror what Alex says in this video!

@AcesDust No not yet :)

@DS2LightingMod has anyone tried it on handhelds like steam deck? lol

Performance testing thanks to discord member Loreciao. Looks like RTX 2060 onwards should be able to hit 60 for HD as well with Quality mode. Was a bit concerned about first gen RTX cards. Specs: 2560x1080 Resolution (21:9) R7 5800x RTX 2070 Super. DLSS Quality (Preset F)

@moosan Yeah correct is not on beta or patreon, it will be for everyone. Thanks for your support :)

@DS2LightingMod Apologies if this is answered elsewhere, but the LE PT stuff isn't available even as a beta in your upgraded patreon tier right? I'm subscribing anyway because I love your work, just wanna make sure I'm not missing a release

LE PT mode. Mostly it is reconfiguring light intensities and exposure, was adjusting the particles, as can be seen from earlier videos they were too bright due to new exposure levels, now they are scaled based on downscaled GI and fall back to scene avg luminance.

@panoskarabelas U got a thank you note from Sam Altman ? lol

I think AIs are training on my game engine...

@nikodems6 You should probably play unmodded version if it’s your first time imo

@DS2LightingMod Thx for anwser im curently playing ds3 for first time i was trying to play your first version of ds3 engine but its bugy and look wierd sometimes and i wonder maybe i will replay it when the mod comes out(ds2 version is perfect)

@nikodems6 That’s early version and not have atmosphere setup or anything so was to test firelink mostly

Performance testing thanks to discord member Vorona, This is RTX 3060 Laptop (1080p) using DLSS Quality, but 2 paths per pixel. FPS varies from 55-60.

@JonathasSSouza Thanks for the compliments

@DS2LightingMod Your service to this community is invaluable, my guy. It hope you know that. The game looks like it's been released today.

@nikodems6 Yea DS3 is after this, it should go much faster than this as all this Tech carries over

@DS2LightingMod i have question man will this mod in full release be ready in this half of the year. and are you going to continue to make lighting engine for ds3 and is it possible to release in 1,0 in this year?
