Are there any good dimension mods?

Are there any good dimension mods? I've seen things like Pocket Dimensions, CustomDimensions, and some others, but is there a mod that makes it more customizable and you can make it however you want?

I installed complementary shaders on its own for vanilla minecraft and they work. I want to add mods through the mods folder from the launcher when you go to open folder and then mods.

World Export Failed By Diesse UI 26.20 [bedrock]

To Understand what I am saying search Youtube on

'How to export world in 26.13+ by gtaguru' and then read this...

So basically we all know that world export by 'Export button Unhider' type packs are not working as the new UI Ore is restricting everything but recently a new pack called ' Diesse UI' is found to have the export template button and it worked for thousands of people but not me.

Just after you click 'Export world' it sure redirects me to file manager but after clicking ' save' on file manager, it auto left minecraft and redirect me to the home page of my device

I tried many methods and it is not working that's why I am sharing this here ( hoping someone will help)

I made a Fabric mod that turns Minecraft into YouTuber-style challenge runs

Hey, I’ve been working on a Fabric mod called Challenge Craft.

The idea is pretty simple: I always liked watching Minecraft challenge videos/randomizers, but I wanted something where you can actually play those kinds of runs yourself without setting everything up manually every time.

So the mod basically turns a normal survival world into a challenge run. You can pick stuff like item randomizers, block randomizers, level border, All Items, All Entities, trivia-style challenges and a bunch of other modes. A lot of them can also be combined, which is where it gets chaotic pretty quickly.

There’s also a lifetime XP system, so completing runs gives you progression/unlocks instead of every world feeling completely separate.

It’s still very much a project I’m actively improving, so I’d honestly love feedback more than anything. Especially:

  • which challenge modes are actually fun
  • which ones feel annoying/unbalanced
  • what YouTube-style challenges are still missing
  • whether the progression system feels worth it

I also added Lockout Bingo, because I think that could be really fun with friends.

Would be cool to hear what people think. Or what challenges I should add next.

Tamriel Recrafted TEXTURES / ENTITIES / 3D / MORE

I’m looking for artists to collaborate on my project Tamriel Recrafted, a mod with a vanilla+ art direction that combines the visual simplicity of Minecraft with a darker RPG/fantasy identity inspired by ESO The Elder Scrolls 3 4 y 5.

I’m looking for artists who can work on any of the following:

  • 2D or 3D weapons and armor
  • Mobs / creatures
  • Individual textures
  • Assets with a Minecraft vanilla+ style that feel readable and consistent in-game

The goal is not to make hyper-realistic textures or assets that feel too far removed from Minecraft. I want a coherent style: simple, readable, handcrafted, but with more personality, lore, and visual detail than vanilla.

This would be paid work, either in USD or an agreed conversion, depending on the type of asset, complexity, and quantity. I’m open to paying an upfront deposit first, with the remaining/full payment once the work is delivered. We can discuss terms clearly before starting.

A large portfolio is not required. I’m interested in seeing your style, your process, and your willingness to work with a clear artistic direction. I believe in paid creative work and I want to support real artists.

I also want to clarify that I’m not looking to use AI for the project’s textures. I want the main assets to have human work behind them and a strong artistic identity.

This is my first time looking for artists for a project like this, so don’t disappoint me. ;)

If you’re interested in collaborating, please send me a message with examples of your work, approximate prices, or any questions, and we can talk.

How do I fix this glitching when using world curvature on fabric BSL shaders

How do I remedy this?

I've tried re-downloading Fabric from the site specifically, but that didn't work.

Any suggestions?

Edit: Forgot to mention, in regards to just “updating” like it says to do, idk where to find the section for that as it’s not telling me where to go to do so. I have tried looking but I simply couldn’t find it. Also I’m using modrinth if that changes anything.

Instance Crashing: java.lang.RuntimeException: Could not execute entrypoint stage 'main' due to errors, provided by 'cardinal-components-entity'

This issue popped up randomly after playing perfectly fine on this exact modpack for almost 30 hours. I have tried removing Cardinal Components and tried installing all the compatible versions to no avail. I get the exact same message regardless.

Let me know if there is a better place to post this because I am completely out of ideas...

Need Help Solving Issue With Running Cobblemon Mod

https://preview.redd.it/yw7s7vin1w0h1.png?width=981&format=png&auto=webp&s=6fb33fd3927aa3773144b3716bc0610cb7412554

When I tried running the latest version of Cobblemon after updating it, I received the errors above. I tried following the instructions from the comments under this post, but it didn't work. I believe it is a separate issue, but honestly I can't really read this since I'm relatively new to modding(especially bug fixing like this). If I had to guess, it looks like the fabric api is out of date, but again, I'm unsure if this is the case. Any help or suggestions would be appreciated!

Conflict with Fabric and Aternos?

Not really sure what forums to post this on, but I can’t load up minecraft at all. I’ve been away for 3 months studying abroad, and this is the first time since I’m trying to get on my aternos server.
I have a backup of my aternos server in 1.21.11, so should I just change my versions of everything to that? I honestly have no idea what I’m doing, so any advice would be very much appreciated!
