case was found where it could cause light to become incorrect But we still get to optimize out any same block updates which reduces light operations

Subject: [PATCH] Optimize Light Recalculations
|
|
|
|
The server triggers light recalculations even if the new block
|
|
is the same as the old block. At this time, BlockData Properties
|
|
do not impact light calculations.
|
|
|
|
So the only way light should change, is if the block itself
|
|
changes from 1 block to another.
