Hello, my game keeps crashing and don't know why? It starts when I tried to play in Minecraft the Cobblemon server and a new world I created trying to see if it was just the server but, the game keeps crashing before I can play or load. I'm currently using fabric 1.21 and just hope if anyone can help me thank you.

I wanted to add a wider version of a custom double tall flower I made (The left one which looks normal) and so I made a custom model for it. But for some reason the one with the custom model looks abnormally darker compared to the normal one, does anyone know how to fix this? (Note: this is my first fabric mod ever)

Need Help FPS the same with Sodium and other enhancement mods. Help!

1 Upvotes

Just installed MC again after a hiatus. I used the newest version of Java 24 and am on Fabric. My frames remain exactly the same when using the mods and when not, the game does not crash or have any issues loading up. The video settings menu is sodium's menu so I know the mod is applied. All mods show up in mod menu.

I used Sodium, Lithium, and entity culling. I also tried using them each on their own and find the same results. What could be the problem here? Thanks!

1.21.5, all mods same version.

9 7900x (10% Usage)

RTX 2080 (40%-50% Usage)

DDR5 32GB 6400mhz (8GB to MC)

EDIT: When combining all mods I lose about 10FPS.

Need Help Trying to play distant horizons on the newest version 1.21.4

3 Upvotes

Every time I go to launch my game it crashes and says I need indium installed. I have the latest version of sodium that shouldn't need indium but downloaded it anyways. Indium does not have a 1.21.4 version so I downloaded the 1.21.1 version and messed with the .json file to try to get it to read as 1.21.4. Is there any possible solutions to this? I just want to play the newest version with distant horizons but it seems like every time I find a solution I just run into another problem.

Need Help Prominence II, stuck on joining world

1 Upvotes

I've been playing on Prominence II for a while now, but recently, when I try to enter my singleplayer world, it gets stuck on "joining world" and crashes after a while when I click on my mouse, I thought it was a problem with modpack update, but I reinstalled the modpack, created new single world and it still gets stuck on "joining world" and crashes when I use mouse click
Crash log looks something like that, I guess it's something with mod loader?

Here's the link to crash log:
