Outdated light when generated underwater lava becomes obsidian

airone01 opened this issue · comments

Client version: 1.12.2 (vanilla)
Server OS: Windows 11
Cuberite Commit id: 95bc2ea

Expected behavior

Underwater lava lakes don't show light, as lava is transformed into obsidian.

Actual behavior

Lava lakes generate underwater, and the light is calculated. The player will thus see light underwater, but there are no light sources, just obsidian caused from the lava underwater.
This doesn't seem client-sided.
Placing blocks on the light source and removing them won't change the lighting.

Steps to reproduce the behavior

Generate a world. I recommend world seed 1293767702.

this is a feature, not a bug. close this report. it is not our problem

Yes, but the lighting coming through (or instead of?) blocks isn't.

I'm not sure what feature you're referencing, this sounds like a bug to me...

its client side

Is it ?
Can you include screenshots of this behavior in vanilla in your comment ? I have yet to witness this in solo. I think the light calculations are handled by the server, no ?

no i cant but i seen some times glitched light engine on 1.8.9 - 1.12.2

like bedrock light on bedrock i seen some times broken light like light with out light source (not the bedrock edition)

it happens allot of times on low light settings

That doesn't prove that it's client-sided. This may simply be a bug in the notchian server as well, as light calculation has always been a bit laggy/broken in vanilla. But as far as i know, cuberite doesn't work the same way at all as the vanilla server, hence the possibility of patching it and hence this issue.
