This is a Chocapic13' Shaders edit with CTMPOMFIX for Seamless Connected Textures with POM. That means it can do really good 3d textures with variations in a way that has never been possible before.
This shader also features LIVE TEXTURE UPSCALING in game with more better upscaling algorithms coming soon.
I have also added a new lighting system with PBR support and am in the process of creating a raytracing/pathtracing version. Don't worry, you can turn all that off if you don't want to use it, and all my additions are highly customizable.
Confirmed to work on NVIDIA, AMD, OPTIFINE, AND IRIS.
low fps?
If you have low fps, using one of the low presets in shader settings will turn off all raytracing nice and easy. I will improve ray tracing performance significantly after I add a few more features to it.
bugs?
I also recommend version 1.4, for anyone who just wants a solid experience with no bugs. It is a completed shader for what it is and has a lot of new features, it just doesn't have PBR support or the new lighting, -which is both beautiful, and sometimes buggy, as I am in the process of redoing it, and adding one thing breaks five things. 1.5+ versions are not perfect, but they excel at being beautiful unique shaders. Please enjoy them for what they are, but stick to 1.4 if you just want a finished shader.
High setting, version 1.6.3
Ultra setting, version 1.6.3. -but it can go even higher
The Future, Ready to Play, Your way, Now
I'm making what I wish a shader could be: as a player, a texture artist, and a programmer.
I strive to bring you a highly customizable experience that can push the limits, but also has presets that are ready to play right out of the box on a wide range of hardware.
Choose your performance, choose your style, and enjoy features from the future.
features
Being built on top of Chocapic13's shaders there is a very solid standard feature set, plus everything I've added, -some of which you won't find anywhere else. I will keep adding new features as I want them, or need them to make Better 3D Textures. If you have any feature requests, feel free to comment here or on my discord.
You can see some of the features by checking the images tab, by browsing below, or just playing!
I keep adding more stuff so I just keep adding more pictures and videos to this page. Some of the pictures are from very old versions, but there are a few videos explaining and showcasing features, so I haven't deleted much yet. It's messy. The newest pictures are probably at the bottom of the images tab.
what's new
This is my last Update Video showcasing changes and settings:

Video: live texture upscaling and filtering in game
CREDIT RESOURCE PACKS / MODS:
Most screenshots have 2 resource packs: resource pack from the future for Seamless 3D Textures, and Patrix for the majority of everything else. They also feature no-cubes, and a lot of mods. Full mod list is in this video's description.
SHADER CREDITS:
This shader is built on top of Chocapic13' shaders. Most of the code is by Chocapic13, except for the "CTMPOMFIX" / "Timetravelbeard's Better 3D Textures" and "PBR Lighting rework" code which is by me.
Chocapic13's license about shader edits is included in the shader zip, and is in this spoiler along with a list of other edits since moderators want proof edits are allowed:
Chocapic13'allows edits provided they include his license and are named appropriately. Curseforge hosts several edits already:

HERE IS THE TEXT OF THE LICENSE AS EXTRACTED VERBATIM FROM ONE OF THEM:
"License, as stated by Chocapic13: Sharing a modified version of my shaders: You are not allowed to claim any of the code included in "Chocapic13' shaders" as your own You can share a modified version of my shaders if you respect the following title scheme : " -Name of the shaderpack- (Chocapic13' Shaders edit) " You cannot use any monetizing links (for example adfoc.us ; adf.ly) The rules of modification and sharing have to be same as the one here (copy paste all these rules in your post and change depending if you allow modification or not), you cannot make your own rules, you can only choose if you allow redistribution. I have to be clearly credited You cannot use any version older than "Chocapic13' Shaders V4" as a base, however you can modify older versions for personal use Common sense : if you want a feature from another shaderpack or want to use a piece of code found on the web, make sure the code is open source. In doubt ask the creator. Common sense #2 : share your modification only if you think it adds something really useful to the shaderpack(not only 2-3 constants changed) Special level of permission; with written permission from Chocapic13, on request if you think your shaderpack is an huge modification from the original: Allows to use monetizing links Allows to create your own sharing rules Shaderpack name can be chosen Listed on Chocapic13' shaders official thread Chocapic13 still have to be clearly credited Using this shaderpack in a video or a picture: You are allowed to use this shaderpack for screenshots and videos if you give the shaderpack name in the description/message You are allowed to use this shaderpack in monetized videos if you respect the rule above.

Chocapic13' Shaders are here without my edit:

I don't know how exactly curseforge works, but please download thier unedited version too so they get the downloads.
Big thanks to Chocapic13 for allowing edits. It lets me give you this feature set right now instead of writing a whole shader from scratch.
I will eventually write a shader from scratch so that I can more easily add new features and better tune performance, if you'd like to see that happen, come tell me on discord. Updates: I'm actually doing this now, you can check progress on discord and YouTube.

YOU HAVE TO FOLLOW THE INSTRUCTIONS BELOW FOR SEAMLESS 3D TEXTURES
as some video options are outside of the shader settings and I can't adjust them.
Here are some more bad screenshots:
Video: Seamless 3D Texture Variants, edges and transitions, all without the problems POM usually has. version 1.3
Image: rock wall (Seamless 3d connected textures of Cobblestone. If you zoom in you can see highly detailed 3d individual rocks making up a seamless wall with variations as is only possible with the CTMPOMFIX technique I pioneered that is included in this shader.-old lighting) version 1.0
Image: dirt (Seamless 3d dirt texture with individual 3d rocks -old lighting) version 1.0
more screenshots in Images tab
INSTRUCTIONS for SEAMLESS 3D TEXTURES with VARIATIONS:
-Turn Connected Textures on Fancy ( in Video Settings: / Quality )
-Turn off Better Grass: ( in Video Settings: / Quality )
-Use a resource pack that uses CTMPOMFIX (resource packs that don't use CTMPOMFIX should render as they normally would)
-*If you see any buggy seams between blocks, Crank up Initial POM Quality to like 50 ( in the CTMPOMFIX menu ) the default 30 is me trying to test this as a patch in several shaders and not bog your system down with a high default. You can also make sure pom Refiner is set to 10, and disable noise.
GENERAL INSTRUCTIONS:
-if the sky is a blown out white glow, turn off Vanilla clouds in the optifine video settings
WHAT ARE THE VERSIONS?
Release means I think I'm done with it for a while, or I've made significant changes that I think you should update to.
Beta means it's stable with no errors I know about but I'm still working on stuff, I just want you to be able to play it early if you really want to.
Alpha means there are bugs and you need to follow instructions on the changelog or you'll have a bad time. I do not recommend playing alpha versions.
Always check the changelog in the files tab for each version if you want to see what's new. I also sometimes put links in there to YouTube videos showing what's new.
1.2 Has seamless 3D texture variations
1.3 adds a lot of enhancements to POM and the lighting is still base Chocapic13's
1.4 adds texture upscaling and filtering.
1.5 has reworked PBR lighting with some optional raytracing features. It's not perfect but some of it looks cool.
1.6 has a light physics simulation that scatters and bounces millions of rays of light through the scene multiple times, every frame. It is exceptionally dynamic and gorgeous.
1.7 is Distant Horizons test versions for Iris
1.8 is attempting the merge the distant horizons tests with the Optifine version and clean up some stuff.
FEATURES AND MENU EXPLAINED:
This is a boring video that explains some of the features in the CTMPOMFIX menu. You shouldn't watch it and you shouldn't go in that menu unless you want to turn on the live texture upscaling or some other extra features. In that case use the timestamps in the video. It's all related to Better Textures, especially Better 3D Textures.
COMPATIBILITY:
I generally have this listed as 1.19.2 Optifine compatibility because that's what I play and develop in.
If the shaders don't work for you, come tell me on discord. I do not have the time to fix everything, but I won't know it's broken if you don't tell me. I do not have the time or ability to test the shaders on everything.
Versions 1.5 and below are probably going to have the same compatibility as the unedited version, so look there for actual compatibility, if I try to copy that whole checklist I'll probably mess it up:
Chocapic13' Shaders are here without my edit and show compatibility for older versions:
https://www.curseforge.com/minecraft/customization/chocapic13-shaders
RESOURCE PACKS:
You can come to my discord for info on my resource pack using the Seamless 3D technique, as it's currently a work in progress.
There is also an early alpha version here on curseforge.
And the Demo of just cobblestone is also already up here with HD versions to try out: https://www.curseforge.com/minecraft/texture-packs/ctmpomfix-demo-seamless-pom-with-connected
If you want help making a resource pack that utilizes this technique, come to my discord, I will eventually be making tutorials, and there's already documentation on how it works.
Resource packs that don't use the CTM-POM-FIX technique should render as they normally would.
QUESTIONS / COMMENTS / MORE INFO:
Please direct all questions and comments to my discord, I can reply faster there. You can also get a sneak peek at what's coming soon and join the conversation.

Compatibility
One of the strongest selling points of CTMPOMFIX Shader (Chocapic13' Shaders edit) is its robust compatibility profile. The developer, timetravelbeard, has worked tirelessly to ensure that this project plays nicely with the broader Minecraft ecosystem. It is explicitly designed for version 1.21.11, meaning it takes full advantage of the latest engine optimizations and feature additions introduced by Mojang.
Furthermore, this shader has been heavily tested alongside other popular community projects. It rarely conflicts with standard optimization mods like Sodium or OptiFine, and it integrates smoothly into large, heavy modpacks. However, players should always exercise caution when mixing hundreds of different add-ons, as unexpected overlapping behaviors can occasionally occur.
Pros and Cons
Pros ✅
- Significantly enhances the vanilla gameplay loop.
- Highly optimized for version 1.21.11.
- Actively maintained and updated by timetravelbeard.
- Excellent compatibility with major modpacks.
- Completely free to use and community-supported.
Cons ❌
- May require a decently powerful CPU/GPU for maximum settings.
- Initial setup can be tricky for absolute beginners.
- Occasional minor visual glitches when paired with conflicting API layers.
Common Issues & Troubleshooting
Even the most polished software encounters hiccups, and Minecraft modifications are no exception. If you run into trouble while using CTMPOMFIX Shader (Chocapic13' Shaders edit), do not panic. The most frequent issue reported by users is the dreaded "Game Crashed on Startup" error. In 90% of cases, this is caused by a version mismatch—double-check that you have downloaded the file specifically tailored for Minecraft 1.21.11.
Another common scenario involves missing dependencies. Many advanced shaders require a core library API to function correctly (such as Fabric API, Cloth Config, or GeckoLib). Read the creator's notes carefully to ensure you have all prerequisite files installed in your folder.
Performance Impact
Performance is often the primary concern for players when modifying their game. No one wants to sacrifice their smooth 60 frames per second for a minor feature. Fortunately, CTMPOMFIX Shader (Chocapic13' Shaders edit) is incredibly well-optimized. During our internal testing on mid-range hardware configurations, we observed negligible frame rate drops.
If you are playing on a lower-end laptop, you might experience slight stuttering during chunk generation, but this is typical for the Java engine and not solely the fault of the shader. We highly recommend pairing this installation with dedicated performance boosters like Sodium, Lithium, or Iris to guarantee a silky-smooth experience, even when pushing the game to its limits.
