Subject: [PATCH] Don't blindly send unlit chunks when lighting updates are
|
|
allowed
|
|
|
|
Spigot, by default, disables several mechanisms around how chunks are
|
|
lit, if ever, which has forced them to always send chunks before vanilla
|
|
would consider them ready to send, causing for lots of issues around
|
|
lighting glitches.
|
|
|
|
Shamefully, the amount of work to relight chunks can be detremental
|
|
to some servers, meaning that forcibily disabling light updates can
|
|
cause major performance issues.
|
|
|
|
as such, we make a compromise; if this "feature" is disabled, we will
|
|
only send chunks which are actually ready to be sent, otherwise, we
|
|
will always send chunks.
