Partial incompatibility with Sodium (Flywheel backend)

[AeiouEnigma]

Create's shafts, belts, crushing wheels, and probably more do not render at all while the Flywheel backend is enabled.

[AeiouEnigma]

Haven't found any issues at all with Sodium when Flywheel backend is disabled

No doubt sodium's internals have changed, but this needs to be fixed on their end

@Jozufozu would I have your blessing in potentially adapting your linked code into a PR to sodium-fabric, in the event I get such a thing working right?

[Jozufozu]

Absolutely, ping me if you get it working and I'll help verify

[AeiouEnigma]

Okay it's not quite as plug-and-play as I was hoping. No improvement when flywheel backend is enabled, and making that change to sodium as-written also newly breaks things when flywheel backend is disabled

This task is officially beyond me lol

[Oliver-makes-code]

It seems to work fine with Indium

[AeiouEnigma]

how

[AeiouEnigma]

Could this be an nvidia issue?

[Oliver-makes-code]

Possibly, Sodium has had problems with driver-specific things in the past

[Oliver-makes-code]

Here's a small update: It fixes it, but only for a period of time, and then it spams the following error in the console:

[22:42:44] [Render thread/INFO]: OpenGL debug message: id=1282, source=API, type=ERROR, severity=HIGH, message='Error has been generated. GL error GL_INVALID_OPERATION in (null): (ID: 173538523) Generic error'

[Oliver-makes-code]

It occurs when chunks are reloaded after the blocks are placed

[Oliver-makes-code]

Gonna look into this to see what the cause is

[Oliver-makes-code]

It looks like that when a chunk reload is triggered via world reload, f3+a, or unloading a chunk, FlyWheel removes the models it needs to render, and Sodium's renderer doesn't call the methods that FlyWheel uses to put them back

[Oliver-makes-code]

ChunkRenderDispatcher$RenderChunk$RebuildTask$handleBlockEntity (ChunkBuilder$BuiltChunk$RebuildTask$addBlockEntity on yarn) isn't called on sodium's side, and that's what FlyWheel uses to re-add the BlockEntities.

Same issue exists on Canvas Renderer, unsure if I should create a new issue since it might be the same error causing it on both renderers.

[Oliver-makes-code]

As of the latest version, It straight up crashes during startup due to a mixin conflict with LevelRendererMixin and MixinWorldRenderer on Flywheel and Sodium respectively

The crash will be fixed in the next Flywheel update.

Partially fixed in builds 343 and 344. Still crashes occasionally but it works now. World launches, belts and entities are rendered properly. Even Shaders are partially working. Great job, @AeiouEnigma

[AeiouEnigma]

Appreciate it, but truly the credit needs to go to Jozufozu and Pepper :)

I only took 2 minutes to merge the existing code from the forge version.

To avoid crashes, just make sure to set /flywheel backend off. Shaders seem to work fine with contraptions if you use Iris's new configuration menu to disable shader-based shadows, if the option exists for your particular shaderpack.

Will try that. Thanks!

Why is this issue still open?

[AeiouEnigma]

Why is this issue still open?

Because using Sodium, even with Indium installed, still results in severe rendering issues when the Flywheel backend is enabled.

[DarianLStephens]

I was trying it a few minutes ago, and everything looked how I'd expect coming from the Forge version.

Yeah, I see. Okay

Have you disabled flywheel backend?

[DarianLStephens]

I haven't.
Just installed the latest artifact and everything's peachy.

Flywheel: Off

[DarianLStephens]

Wait, is it off by default? I just noticed that text on the right, but I haven't run that /flywheel backend off command.

Not sure. Maybe it should be Off

[RedWideWeb]

@AeiouEnigma should Flywheel be marked as Off in F3 menu

[DarianLStephens]

Running /flywheel backend batching crashed the game instantly.
Running /flywheel backend instancing does the same.

I guess that means it was off the entire time and I just never noticed.

Known issue with Iris, though we haven't actually opened an Issue about that

For me it was instancing by default. So before I disabled it i ran just /flywheel backend and it printed default value which was instancing for me.

[AeiouEnigma]

Running the /flywheel backend instancing or /flywheel backend batching commands with sodium installed results in various blocks having messed up or non-existent rendering

[DarianLStephens]

Yeah, Iris does not like this.
Turning shaders on made contraptions (the windmill) disappear, and turning them back off just crashed the game.

With Iris off, it's defaulting to Instancing, and I'm seeing the same issues as here.

Batching just makes it all disappear:

For shaders disable Realtime shadows. This fixes the Windmills

[AeiouEnigma]

If the world loads while the flywheel backend is enabled, things will probably look just fine until the renderer reloads.

Contraptions not rendering with certain shaders enabled is another known issue. If the shaderpack has an option to disable shadows, that may 'fix' the problem.

[DarianLStephens]

Interestingly, newly-placed blocks seem to render just fine, but toggling Flywheel or using F3+A makes things disappear.

The cogwheel was even spinning.

[DarianLStephens]

More of things working after replacing the blocks manually.

[RedWideWeb]

There are no shafts on the gearboxes

[AeiouEnigma]

Alright I appreciate it but you can both stop updating on every minor detail lol, the issue is known

Okay, sorry.

[AeiouEnigma]

No harm done 😄

[PepperCode1]

This was fixed completely in Flywheel as of yesterday, and I am not aware of any issues with Create specifically, so I am closing this issue. If there are other problems please open a new one.
