Photonics: A raytracing engine

Changes

• Increased default accumulation frames to 32

Bug Fixes:

• Fix denoiser artifacts at low resolution
• Fix photonics.enableBlockLight not working with ReSTIR

Bug Fixes:

• Fix Gi being disabled by default on simple lighting

Changes:

• Added 2 additional spatial reuse passes for disocclusion. This is another big improvement to ReSTIRs noise while in motion.
• Improved clarity of simple lighting in motion
• Added new option ReSTIR Combined Gi, which passes Gi through ReSTIRs denoiser, improving clairity at the cost of performance and noise.

Bug Fixes:

• Fix black stripes on Gi with low resolution
• Fix more Photon issues with LOD chunks
• Fix ReSTIR breaking when handheld lighting is disabled
• Fix ReSTIR denoiser artifacts when using low render resolution

Supported shaders

• Photon (requires latest version from Github)
• BSL v10.1 (exact version)

Changes:

• Added a new lighting method (ReSTIR), disabled by default. Compared to Simple (the old method), ReSTIR can trace up to Max Lights at the cost of a little noise.

• Improve GI flicker at large distances (especially with low render resolution)

• Max voxelized block states has been increased from ~4k to ~8k

• Photonics will now show an error message in chat if the max voxelized block states has been reached

• Added a new option to adjust the strength of lighting from held enchanted items

• Added a new global toggle for 3D Blocks in Photonics settings

• Added SSR fallback when using WSR with Photon

• Change handheld lighting to calculate independently for each hand. It will by default use 2 rays for visibility (meaning each hand will cast its own shadow!), but can be changed to a single ray in settings

• Made handheld respect falloff/radius of lights, it should now look more similar to lights placed on the ground

• Made handheld properly interact with normal mapping

Bug Fixes:

• Fix 3d blocks being broken by 3d leave packs
• Fix max lights breaking above 1000
• Fix lighting being gone in LOD (Voxy/DH) chunks with Photon
• Fix GI flickering with TAA enabled with BSL
• Fix handheld not respecting main hand in skin settings

Supported shaders

• Photon (requires latest version from Github)
• BSL v10.1 (exact version)

Release made by @Essentuan

Changes

• Added photon patch (with world space reflections!)
• Eclipse shaders now have native support for Photonics
• Transparency support
• Added some new options to BSL and Photon
• Shader API
• Fast response times for RT (Photonics should now react almost instantly to world changes!)
• Rewritten config system + New light values/colors
• Fixes for some 3d blocks being black
• Fixes GI starting out as green
• A new shader-patches folder in .minecraft
• Fixes BSL10.1 compiler errors in the end

Supported shaders

• Photon (requires latest version from Github)
• Eclipse (requires latest version from Github)
• BSL v10.1 (exact version; TAA is broken!)
