sodium-fabric-mc1.17.1-0.3.3+build.8

Expected Behavior

When I began using Sodium a few months ago, I immediately noticed the performance improvements. This was expected/as advertised. However, I also expected Sodium to render things to look the same as they do in Vanilla Minecraft. This turned out to not be the case. For months now, Sodium has completely failed to render water columns correctly.

Actual Behavior

To demonstrate the problems that have existed in Sodium and still exist in Sodium with water rendering, I constructed a hollow column of barriers, into which I poured a water bucket. Only the top water block is a source block; the rest of the column is downward-flowing. It looks like this:

I then positioned myself at a specific angle, looking at the water column, and I took screenshots of the column in Sodium 0.3.2, Sodium 0.3.3, and Vanilla 1.17.1. Here are the results:

1. Sodium 0.3.2 produced strange, segmented blotches of darker color in water columns when looking at them from odd/oblique angles. I am glad to be rid of this strange behavior.
2. Sodium 0.3.3 produces a plain, translucent, completely untextured column. How the heck did you guys let this happen?

Next, I converted the entire column of water into water source blocks by placing kelp all the way up the column. I then positioned myself at the same angle as before, and took screenshots in the same three versions as before. Here are the results:

1. Sodium 0.3.2 strangely refuses to render any of the water in a column of water sources filled with kelp. Once again, I am glad to be rid of this wacky behavior.
2. Sodium 0.3.3 renders both the kelp and the water, but once again, the water is completely untextured.

Reproduction Steps

Make a column of water, then run/fly around and look at it from assorted angles. Seriously, that's all you have to do.

Layered translucency effects are not yet implemented, so the behaviour you're reporting with just water in 0.3.2 is a duplicate of #38
The kelp issue is a duplicate of #913, which as you can see is fixed in 0.3.3.
The untextured water situation is new to me, and I can confirm it. Not sure if this may have the same root cause as #38.

damn, i forgot to test barrier blocks, this will be broken also for light blocks.

now on to why did this happen?
simply i never tested with barrier blocks, totally forgot they existed and turns out they have a totally different interaction with water. Glass and other transparent objects will set the water to a non-animated texture. Special blocks such as these go against that assumption.

it'll be caused by this here https://github.com/CaffeineMC/sodium-fabric/pull/892/files#diff-3486df2d697d632a02fa5eaeb85a0590a3a1e89df7c11488eeb9cf8b92d41fbbR324

the fix looks to be pretty simple, instead of checking for air i should have been checking adjBlock.getRenderType() != BlockRenderType.INVISIBLE which seems to work correctly

Please keep this tone out of issues in the future.

This is a free project that attempts to re-implement the entire chunk rendering pipeline. Like all software, it is subject to bugs. Water rendering in Minecraft is full of special cases and has been continuously hacked on to with every update of the game. It is not entirely straight forward to fix all these cases, and we sometimes miss regressions when one hacky behavior breaks another hacky behavior.

Please keep this tone out of issues in the future.

You know what, you're totally right. My bad.
Compared to a few other mods on which I've reported bugs, you guys pleasantly surprised me with how quickly you addressed this issue. You have my thanks and my apologies for the manner in which I originally reported this.

Real quick, can I ask a question about the labels you have added to this issue?
I'm curious about the B-1.17 label. Does the addition of this label mean anything about whether or not this will be addressed in 1.18 Sodium?

This plain texture is used in vanilla for water which is against glass, but Sodium appears to use it much more liberally. For example, it appears next to signs, and also results in the inside of water just not having any texture planes:

Yeah, I've noticed some stuff like that. I mean, I really appreciate how much optimization Sodium is able to pull off. Without Sodium, my computer can't get any better than like 20 fps in Minecraft. I just wish they could figure out how to make water look right.

Still happens sadly and it's really jarring to look at. It's especially jarring behind ice or even worse behind tinted glass.
Some of the water textures vanish and some remain in form of odd squares and rectangles poking out.
Like so:
#1214

Still experiencing what looks like faces inside flowing water rendering incorrectly on sodium 0.4.1 - is there a way to fix this on my end I am unaware of? As you can see in the screenshot below, it happens when the water is not next to a solid block.

Closing this issue and moving to a new one at #1369, as this issue is still present in newer versions of Sodium and Minecraft.

We know the issue still happens, and it is being worked on. Creating new issues to report the same problem so that it "gets looked at" is not going to result in anything but the issue tracker getting spammed.

According to the author of PepperCode1/Continuity#245, this bug still happens, but when the overlay texture is used should not deviate from vanilla since commit a2bb59e. Does this issue still happen or is there a different but seemingly related issue?

The incorrect water overlay sprite has been fixed. The water having "holes" inside of it when looking at it from certain angles is a different issue (#38).
