pre 1.13 blocks over water rendering issue

[terbin]

There is an issue rendering blocks directly over the water in pre-1.13 regions perhaps.

There is a layer of snow at y=63 directly over the water.

Here is the example 1.12.2 region r.-74.-93.zip

Rendering the 1.12.2 region with latest minutor - rendering incorrectly. 4 Chunks not rendering snow at y=64

Updating the region to 1.19.2 and rendering it with latest minutor - rendering correctly

When I open this Region file in NBTexplorer and look to these Chunks (e.g. -2349/-2945 versus -2349/-2946)

• (I see that there is a Section Y==14 with some glass)
• Sections 0 to 4 are present which is expected, as 16 Block layers per Sections is 0..3 for 0..63 and another one for 64
• Section Y==4 contains Block data field and Data data filed with all 0 -> AIR
• Section Y==3 contains one last layer of snow (0x50 -> ID=80)

So it would be expected, that there is NOTHING above Y>=64

When I open this Region in Minecraft 1.12.2 I can see your snow Blocks . . .

What is interesting is, that it works in Chunks that are located more to the north. It seems, that only these Chunks are affected that have the glass layer at Y==239

Good point here's a bigger section - one more region to the south. It's pretty strange

1.12.2 region file

updated to 1.19

Your build looks nice, Christmas themed? Maybe you could add that Region file also? Than I have something to show for the kids ...

Hi Etlam,

Absolutely - here is the world download with level.dat Emperium Christmas Base 2019-12-25.zip

It's from an anarchy server called 2b2t, so while I've removed some signs, better doublecheck before you show the kids. I run a mc museum server for destroyed builds from that server: thearchive.world

Something your kids might enjoy are my cinematics from that server: https://youtube.com/terbin
