Layered translucent blocks do not render correctly
RdSt14 opened this issue · 28 comments
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
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).
With Sodium:
Without Sodium:
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.
when looking throught stained glass, air and then more stained glass, parts of it are missing:

Note that this issue affects subchunk borders, not just chunk borders. You'll see the same effect on the vertical axis, if you cross borders.
The issues with slime and honey blocks seem to be at least partly fixed in the 1.17 beta version.
1.17 beta version "seems" fix this issue, but in some cases it's still werid(For example the slime block behind white stained glass).
more pics ig, havent seen anyone mention how borked kelp is (except for the topmost part for some reason?)
I notice this bug while viewing a column of water threw a multichunk plane of glass and notice it only effected the water and stained glass in the same sub chunk
.
I noticed the kelp and water appear to render incorrectly with many blocks, not just glass. This was on version 0.3.2+build.7
Also, all one-block tall ice appears to not render any submerged parts.
This bug is:
- issues related to interactions between multiple layers semi-transparent blocks, such as water, ice, stained glass, nether portals, etc.
This bug is not:
- issues related to blocks with clip transparency, such as glass
- issues related to one layer of translucency, such as the water + kelp rendering issues reported in #932
We know a lot about this bug already. Please refrain from posting unless you have something new to add.
I want to add to this issue two further things that I noticed:
- only happens with stained glass
- weird things happen on chunk borders
Here are two pictures from 1.18.1 (0.4.0-alpha5+build.9)
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.
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
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.
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!
