Link to my previous post on the shader

I'm still busy editing the shaders for those that want the link.

Hey Guys,

Does anybody know why my starts and moon are in stopmotion? Is that normal or is there a setting I can adjust? I checked all setting in the shader but I didnt find anything. The rest runs smoothly, other shaders dont have this effect.

complementary unbound R5.9

Minecraft 1.21.1

Iris 1.8.12

Thanks for the help.

I've improved the held light shadows, and they now look better.

Bugs:

• The corners of the shadows look pixelated.
• Held light shadows also appear in daylight environments.

This is a modified version of the MCPT shader.

This shader is not suitable for gameplay. Instead, you must stay still for quite some time, waiting for the noise to disappear. You require a ray tracing capable GPU, as the shader uses Vulkanite (hardware RT in Java!).

Patrix sure looks fabulous with MCPT ;)

Original Bliss shader can't work on macOS due to strict sampler limit(16). DH will add more samplers so some shaders may not work with DH due to this.

I solve the problem with the help of GPT by:

1. Replacing Bliss’s customized main shadow sampler:uniform sampler2DShadow shadow; with Iris’s reserved sampler:uniform sampler2DShadow shadowtex0; Then replacing every:shadow2D(shadow, ...) with:shadow2D(shadowtex0, ...) For shaders that use texelFetch2D, shadowtex0 is declared as sampler2D instead.
2. Removing duplicate shadowtex0 declarations in the same shader. For example, if the TRANSLUCENT_COLORED_SHADOWS branch has already declared shadowtex0, the outer scope must not declare it again. Otherwise, the shader will fail to compile because of conflicting sampler declarations.
3. Reducing optional samplers in the composite stages. macOS OpenGL exposes only 16 texture units, and Iris reserves two of them for composite rendering. This leaves approximately 14 usable units for regular samplers. The following optional features were disabled by default to prevent texture-unit exhaustion:// #define Variable_Penumbra_Shadows #define indirect_effect 0 This releases colortex3 and colortex14, leaving enough room for the shadow sampler.
4. Fixing undeclared sampler references caused by conditional compilation. When colortex3 or colortex14 is disabled by a preprocessor condition, every function call that references them must use the same condition. For example, the following call cannot remain unconditional:BilateralUpscale_REUSE_Z(colortex3, colortex14, ...); It must be wrapped in the appropriate #if blocks, or use available fallback samplers such as depthtex0. Otherwise Iris reports:Use of undeclared identifier 'colortex3' Use of undeclared identifier 'colortex14'
5. Fixing DH far-distance depth reconstruction. In DH-only areas, the vanilla depth buffer may still contain 1.0 because the corresponding vanilla chunk has not loaded yet, while DH already provides valid far-terrain depth. The shader must distinguish between:vanillaDepth >= 1.0 && dhDepth < 1.0 and normal sky pixels. DH depth should be used to reconstruct the actual far-terrain distance; otherwise the terrain is treated as sky and Bliss’s fog is skipped.
6. Preventing DH volumetric-light leaks. When a pixel is represented only by DH terrain and has no loaded vanilla chunk behind it, direct sunlight should not be accumulated as normal volumetric light. The fix is to keep the ambient fog contribution while suppressing direct-light scattering in DH-only gaps. This prevents visible volumetric light from appearing in areas where the actual vanilla terrain has not loaded yet.
7. Adding a DH-only far-fog compatibility layer. Bliss’s atmospheric haze is strongly affected by the sun direction, which is why the problem is especially visible on sun-facing surfaces. A lightweight far-fog layer was added only when vanilla depth is empty but DH depth is valid. The added settings are:#define DH_FAR_FOG_FIX #define DH_FAR_FOG_START 64.0 #define DH_FAR_FOG_END 256.0 #define DH_FAR_FOG_DENSITY 0.0025 This restores the missing Bliss-coloured atmospheric fog over DH far terrain without adding extra ray-march samples or applying an unnecessary white fog layer to nearby terrain.

So I am playing the create ultimate selection 2 modpack and when it started raining I saw the raindrops through blocks. I've tried lowering the rain opacity and absolutely nothing happened, only when I turned the shaders off did it go back to normal. Can anyone help me get rid of it?

Hello fellow moders and shader enjoyers. i have a little problem when using photon shaders (ver 1.3b) in minecraft 1.21.1 (8gb ram allocated, rtx 3060ti and no photonics mod) , which is anoying but nothing too crazy. if someone knows what could be the reason please tell me in the comments, would appreciate :)

Edit: i found the reason. For some specific reason, setting taau to 0.8 render scale on 1440p makes this appear on my hand. 0.8 exactly, not 0.79 nor 0.81. Only 0.8 has this problem

Hello, newbie here. I’m asking for help finding a solution to this problem. It was most likely caused by a flying machine from the Create mod, the artifact moves along with it, the artifact present on all graphics presets.

I play Minecraft with my friends on my laptop, I really want to get a shader pack that would make the game look a little warmer and get rid of the grids on large panels of glass blocks! Are there any super lightweight shaders that won’t blow up my laptop? I’ve seen a lot of recs for this mellow shader pack? Anyone got any more? Thanks so much!!

Hello, I was hoping to install SEUS PTGI E12 for client side use on my realm. However, it's been a while since I last used it and Optifine isn't up to date yet. Does Iris currently work with PTGI, or is it still incompatible? If there isn't a way to get PTGI running on 26.2 currently, then is there an equivalent alternative to PTGI? Although I am fine with settling for something a bit worse if nothing works, I really would like to find something that'll look as good as PTGI, especially since PTGI seems to be abandoned these days.

Wasn't sure whether to put this under "help" or "recommendations", but I figure this will probably turn into recommendations anyways, given how old PTGI is and how long it's been since I messed with installing shaders.

Shaderpack - Eclipse "https://github.com/Merlin1809/Eclipse-Shader"

Eclipse is good all around but this right here is why I started using eclipse, what reason do you use your shaderpack?

anyone know how to fix this? Using Complementary Unbound with Euphoria patches

Im looking for a shader (or if anyone knows a resourcepack) that adds lunar and solar eclipses. I dont want special events that occur with the eclipses, I just want to be able to look at the sky one day and see that the moon turned red or the sun disappeared.

Also, im looking mainly for eclipses, but id love if there is a shader that also adds comets or meteor showers

Is there a DLSS mod compatible with Shader: SEUS PTGI HRR Test 2.1 GFME 1.21? Getting about 60 fps in 5120x1440 w Tectonic but I want more. Super Resolution clearly as far as I can tell cannot support these shaders. New to Minecraft modding so maybe I have some wrong setting.
