What happened?

Skybox doesn't load before or after defeating the Ender Dragon. I've turned off and back on the custom skybox fully reloading my client each time. There is not a pull down for Minecraft 1.21.1 Version which is the one I'm using. Maybe unrelated but I am seeing some odd terrain gen in the void from the main Island. And with those crystal spires.

BetterEnd

21.0.11

BCLib

21.0.13

Fabric API

0.103.0+1.21.1

Fabric Loader

0.16.5

Minecraft

1.20.4

Relevant log output

I am unsure what is relevant. https://mclo.gs/Y1v3rFX

Other Mods

All mentioned in the log link above. Going to trim the fat and test with only Better end and relevant dependents.

Update with only BCLib 21.0.13, BetterEnd 21.0.11, Fabric API 0.103.0+1.21.1 and World Weaver 21.0.13.

Client completely reloaded for each example below

Custom Skybox: False

Custom Skybox: True

I too am having this same issue, tests and all. My guess is something to do with the addition of World Weaver being introduced, so hopefully we see a fix soon.

I've been going crazy trying to figure this one out myself, but I've got nothing. I even cobbled together an update for BetterEndSky (the standalone End sky mod derived from BetterEnd) using the sky renderer code from BetterEnd but that gives the same result, a blank gray skybox. My suspicion is that something is borked in BetterEndSkyRenderer.java that's preventing the textures from being applied, but I have no idea what.

Really hoping this gets fixed before the next major update, I love that custom sky.
