DS3LE-PT In motion Cruxifixon woods. DS3LE volumetrics and path tracing add so much depth to scene here. Very happy with testing , super optimistic of release in few months. I also enable/disable DLSS-5 to show comparision to show what it actually adds to scene www.youtube.com/watch?v=NJkj...

DS3 has lot of LODS for every mesh. In LE I can add the base LOD to the BVH, as LE doesn't know when the LOD is actually swapped in main view, this will create self-intersection issues, however added a feature to detect these cases and path tracer will do a stronger ray bias

Sun transclucent shadows and much better window support(sky lighting) in DSLE-PT. Will also be updating DS2LE (Few windows in Drangleic castle later)

dslightingengine @dslightingengine.bsky.social · 07/07/2026

DSLE - Editor feature/Subsurface. These meshes are "Static" but are not rendered as normal foliage. So added a feature to mark the Base game meshes as "Foliage", which disables screen-space shadows and also enables transmission/SSS on the leaf meshes

dslightingengine @dslightingengine.bsky.social · 02/07/2026

Large emissive meshes. 100k triangles, emit light and shadows, however importance sampling is not done by not including them in LightBVH, so the normal BRDF sampling catches them. This makes them essentially free of cost as the path tracer picks the emission based on the hit. Descriptions below

dslightingengine @dslightingengine.bsky.social · 01/07/2026

Implemented Caching mechanism for Skinned objects. Now the BLAS is rebuilt only if the mesh has changed enough. The build time drops from 5-6ms down to 0.5ms . Without caching it dropped to 45FPS here. LE uses double buffering and Async build as well for GPU.

Looking for help testing something in Dark Souls 1. Do you have DSR on Playstation, can go online, and have a character with a Red Sign Soapstone? If so I wanna check out some obscure thing that might've been added by QLOC to the remaster.

Darksouls3 has excellent LOD placement and many places are visible from each other zones. Firelink/Lothric wall are actually fully connected too. This is one instance. Similar behavior like Lothric wall LOD is correctly placed from COTD/Cruxifion woods 1/1

Working on improving Foliage shading with subsurface and transmission. DS2LE is using Beubeu Faraam Preset for testing and DS3LE is WIP for release end of year. Thanks to NRD Author Dimitrii Zhdan for guidance on changes with updates to NRD-Sample

Integrating OMM , the latest DXR 1.2 features in LE. Left is AlphaTesting in Shader(Max 5 tries). Right is OMM for the meshes(2 state) and Subdivision level of 6. It saves about 2.5ms to 3ms. Yet to optimize fully like arranging OMM buffers contigously for all meshes.

DS3-PT. Lothric wall progress. DS3 areas are much brighter than DS2. I held back sun power a lot in DS2. Aerie/Loyce are probably only 2 places where sun is >10000 lux. Most places are cloud or dark.

Working on PT in DX12, made me understand CPU/GPU timelines lot better. DS3 uses deferred command lists to render. LE overrides camera for Jitter/ReverseZ and also for editor. Jitter/ReverseZ are ensured that they are updated, UpdateSubResource was done during draw-call while tracking dirty flags.

I wish there is a Bluesky feature I can write all this in one Post. It's primarily why I have X-Blue. Writing long tech posts with explanations and splitting it in multiple posts, loses a bit of context.

While studying SER(Shader Execution Reordering), I came across a blog which showed that Pipeline tracing i,e (TraceRay) is faster than Inline tracing(RayQuery) on AMD GPU, SER requires PipelineTracing(Dispatch Rays) call. AMD GPU's see a 10-25% speedup using TraceRay vs RayQuery.

Thanks to Dmitrii Zhdan(NRD Author) for including the Cavity shadows which I had showcased earlier now as part of NRD Frontend. As mentioned earlier It works amazing with NRD-SH modes when combined with Parallax mapping.

Added GT7 Tonemapper as an option for SDR/HDR Monitors. The difference is in the behavior of Highlights. Tweaked the Filmic (toe) to give the similar contrast as GT7 default and readjusted manual contrast added in dark areas. Left : Filmic (John Hable) Right : GT7

Shrine of Amana. OG Vanilla vs Default LE vs Scholar. Personally as I have said before I like the more natural CG vanilla. Scholar puts a green tint on things, change color. LE one has all the blue flowers as emissive as well

Path tracing and Auto exposure go hand in hand. PT allows extreme low light propagation, the data is there but requires huge exposure ranges to show it. Here Moon light is only 10 Lux. Should probably view this video on your monitor Youtube : www.youtube.com/watch?v=lEzV...
