Layered translucent blocks do not render correctly

[RdSt14]

Expected Behavior

Water will be visible inside glass stained pipes, commonly used in water elevators

Actual Behavior

Water is not visible through stained glasses, although items can be seen flowing

Reproduction Steps

Make a water tube, doesn't matter if its flowing or a water elevator type.

also it show other weird thing like the sky rendering black instead of white or stained glass can't show other stained glasses behind them

[jellysquid3]

Sodium does not implement quad sorting for translucent block faces, leading to all kinds of translucency issues. I'll be making this a tracking issue for other problems caused by it.

Can confirm all kinds of weird behaviour with translucent blocks.

You can even see chunk borders in ice:

More images of the issue

no rendering issue when water rendering isn't effecting the block

Only top texture on the block renders through water

As a result of the issue above, you cannot see certain transparent blocks above you while inside of water

Issue applies to flowing water as well

Also, portals are invisible behind glass.

See this video by Xisumavoid for another example of this issue with Honey Blocks (they are almost as see-through as glass, even though they shouldn't be that translucent).

Nether Portals also not showing up

Just in case this is useful, not sure if I'm rehashing what's already known -

I'm getting same rendering as @zLauch on f577eb2 (and also on ishland's 1.16.2 support PR, though evidently that's not the actual cause) but not 0.1.0. Hardware is AMD Mullins, happens with all of sodium's rendering modes.

Java is version 1.8.0_262, using 64-bit architecture.

Not sure if this is helpful/already known but it seems like on chunk borders translucency effects are less broken? I've only tested it with honey/slime blocks but it seems like when you have two blocks on either side of a chunk border the middle part gets rendered correctly. The image should be a bit better at explaining.

Water in a water column renders with strips and breaks off directly on the borders it seems like. This changes while you move through the column where you can see random vertical and horizontal "panes" of darker water.

Not sure if it's been referenced elsewhere but on subchunks it adds slices/faces to water

I have the same problem with glass not rendering through water.

[RedstoneManiac3Xbox]

is there an actual implementable fix for this yet? or am I gonna be stuck not viewing the waterfalls in my terrarium?

No, it's a WIP. See: pull request

[FreezePhoenix]

Don't know if anyone has noticed - but this only affects things that are placed in Translucent render layers. This includes water, tinted glass, stained glass, honey, slime, etc. It would appear that faces are simply sorted by some insertion order.

[JaehaerysWise]

Posted another issue about water rendering issue in stained glass, but I feel like I should add it here as well

Please stop!

...adding yet more images of the same thing

This bug is being actively worked on, and we don't need any more information about it.
Instead, sit down, relax, and wait patiently.

Thanks!

This problem will be resolved in Sodium 0.6 with the introduction of #2016.
