Icarus shaders -February 2025 (early access updates)

Developed for iris, tested in minecraft 1.20.1. If you get bugs in other mc versions let me know!

Version Numbers: version numbers are the date I made them, the newest is usually the best. (It's Year-month-day format)

Attachments:

'Icarus feature fixes v2' is a resource pack that fixes the color of the '3D grass shader', it is also inside the shader.zip, it might need to be loaded on top. Don't use it if not using the 3D Grass shader or grass dirt will look green.

Modpack: this is my main test environment: https://modrinth.com/modpack/timetravelbeards-1.20.1-modpack

Versions:

2025-2-28

• Much less Noise Underground & indoors

• much better reflections & lighting underground & indoors

  • these are because of having diffuse bounce light in offscreen reflections & lighting now (just using lpv for now)

• Sand Test 2: try it with the config you can download below (the config is the '.txt' file)

2025-2-19

• fixed intel crash

• working on physics things

2025-2-17:

• fixed intel crash (hopefully)

• rain improvements

  • less noise

  • rain ripples in puddles are crisper, zero smearing

  • lightning no longer messes up TA making static indoors & underground

  • rain ripple speed defaulted 50% faster

2025-2-15:

• fixed 'Low' preset being dark/broken

• added 'Smoke Physics Test' preset, it's slow, noisy, and smeary. I still need to redo the fog renderer. 

  • menus for that started in 'Testing/lpv_fog/physics', including hd fog and even vortexes when entities move through fog that will look good later, and other options to have it less blocky/more smooth.

  • you can change the cloud style and then you won't see the mist but it will still wet spots in caves, swamps, jungles, etc. -it's very much just testing.

• there are still crashes and bugs i'm working on, but didn't want to withhold atleast some weekly progress

2025-2-7:

• 'fixed' tree leaves sometimes flickering -but they have the old noise back until i actually fix it, you can revert this change in the 'lighting styles/vanilla+/fancy block light/LPV' menu by using 'render plants as entities' rendering as entities is to have no noise from raytracing

• integrated pbr: gems can re rendered as metal or glass (metal is much more reflective and tints reflections)

• integrated pbr: default metal roughness is adjustable

• integrated pbr: default glass reflectivity is adjustable

• fixed gap in reflections between voxel tracing range and cubemap, if you still see a gap i'll fix, the minimum cubemap range is really adjustable now, it's a slider in the 'cubemap' or '360_EL_Advanced' menu to tune this better later

• Smoke /Mist Physics: (Testing Menu & Still Buggy)

  • mist from waterfalls can get stuff wet (see upcoming youtube video)

• BUGS:

  • shadows are ghosting instead of instantly updating, I'm not sure when that broke

  • mobs are too dark on shadowed sides out-doors. (this is what's also messing up tree leaves when rendering as entities to have no noise)

• Working On:

  • bugs

  • physics for terrain and volumetrics

  • better / faster fog rendering

  • lighting quality / noise reduction / better global illumination

2025-2-4:

• bug/crash fixes (hopefully)

• test 2 of smoke/mist physics (i still need to redo the rendering & add a faster fog renderer separate from cloud style 5

2025-2-2:

- fixed lava looking broken very bright and flickering squares, added better voxel lighting and voxel reflection

- 'Create mod' page in:  'more settings/mod compatibility' with option to remove smearing on moving blocks (but it currently makes other block entities lose lighting quality, I'll try to fix later)

- removed lilypads and wilderwild:algae from having buggy voxel reflections in water

- removed all blocky reflections bugs from water

- removed on screen light sources from reflecting as voxels

-'lava Falls' defaulted on on all presets but low and cartoon

-minor bugs

-Fixed water losing reflections in rain

-Fixed so that rain ripples show up on water again

-Block light in Fog testing menu has one opacity slider 

-Smoke physics started

-LPV Fog options
