[Issue]: Cauldron Rendering issues with Sodium

[SplendidAlakey]

MC 1.18.2
Fabric API 0.51.1
Jello 3.2.2
Mo'Structures 1.4.2
Sodium 0.4.1
Indium 1.0.3

To reproduce:

1. Install the mods listed above and the dependencies for Jello; Mo'Structures is likely not needed, because it adds no new blocks, but it's extremely easy to reproduce the issue with the mod installed and that's the method I will be describing
2. Load into any world, you can create a new one; also doesn't matter if it's single-player or server
3. Type /locate mostructures:the_castle_in_the_sky in the chat; teleport to the location it gives you
4. Look up, find the floating island, fly around it until you see this:

Edit: forgot to mention - removing Jello or Sodium fixes the issue.

Hmm that is Really interesting Log... Some how a Skull Block Entity is somehow being cast to one of Jellos internal Color Block Entity for Cauldrons... wtf

[SplendidAlakey]

There is a skelly skull in this structure, maybe Mo'Structures places it in a some "hacky" way. But by just looking at it I couldn't spot anything abnormal, it just looks like a regular skeleton skull placed on a block. And since Mo'Structures doesn't add any new blocks or anything like that, it must be reproducible in vanilla + Jello.

And how were you able to tell it's specifically a skull and that it tries to cast to a colour blockEntity for cauldrons from my logs? Asking because I'd like to get better at reading logs. All I could gather was that it's some coloured storage blockEntity from Jello 😄

[Dragon-Seeker]

The class name is obfuscated due to how minecraft is compiled and de-compiled so its just given a generic class name that can be put into a mapping bot in dev discord servers to find what class it really is. Typically via a /mapping command using the Linkie Discord Bot.

The main issue is that a disconnect possible due to structure generation with a near by Cauldron as that Block Entity is used for storing custom cauldron color so from what the log states there seems to be cauldron at a skull blocks position in the world somehow which really makes no senses

Ahh, got it. I thought maybe there was like a website with all vanilla classes deobfuscated. Thanks for the tip.

Went inside the structure, and there is indeed a cauldron next to a skull. Not sure if it's guaranteed to spawn next to a skull, but possibly? Will try placing skulls next to cauldrons without Mo'Structures and see what happens.

[SplendidAlakey]

1. Created a new world
2. Got a cauldron, a bottle of water and a skeleton skull from the creative inventory
3. Placed a cauldron down, then placed a skeleton skull next to it just like above
4. Filled the cauldron with water using bottles - water did not render at all
5. Breaking the skull allowed the water to render
6. Placing the skull down again made the skull invisible

Well that is great to know and really god dam concerning to say the least.....

[Dragon-Seeker]

What's worse is it dose such with any Block Entity as I just tested it with a chest and it proceed to output a similar error.

[Dragon-Seeker]

Seems to be a weird side effect of Sodiums Biome Blending that will attempt to blend the nearby blocks and use the Original blocks color method to do such causing the issue

[Dragon-Seeker]

Its now fixed but it now causes cauldrons to render color very wrong(Issue on sodium repo... There may be a way to add compatibility with sodium though

Without Sodium:

With Sodium:

[SplendidAlakey]

Does disabling biome blending in Sodium options fix it? If there's even such an option still (the thread on Sodium's repo is fairly old). If yes, then I might also just use that workaround for now.

[Dragon-Seeker]

Ill add a check as It shouldn't matter for internals of fabric and/or minecraft to prevent this bug from happening but will keep this open until I can find a solution to prevent the incorrect color blending.

[Dragon-Seeker]

Patch for the Rendering Crash in the latest version: 3.2.3+1.18.2

[SplendidAlakey]

will keep this open until I can find a solution to prevent the incorrect color blending.

There's a mod that promises to fix that: https://www.curseforge.com/minecraft/mc-mods/unofficial-sodium-biome-blending-fix

I'm currently taking a break from MC until 1.19.1+, so didn't test the mod myself, but decided to link it in case someone finds this thread.
