Torch Optimizer shows numbers on the ground to help you to place torches or other light sources for maximum mob spawning blockage.


The default shortcut key to turn on/off light level overlay is F7. You can change it in “Options -> Controls”.   You can use Shift + F7 to toggle sky light calculation. Ctrl + F7 to toggle overlay display (1.12.2 & below)   Initial Version to 1.12.2-2.0.4
, (comma) to change the optimal torch position by plus one. . (period) to change the optimal torch position by minus one.
[ (Left Bracket) to change the optimal torch position by plus one. ] (Right Bracket) to change the optimal torch position by minus one.


If you enable optimizeEnable in the gui config you will get an asterisk placement on the ground at position number 2. However you can further change where the placement will be from 0 to 15.
