Issue description
When creating a block, Light opacity is described incorrectly:
This property makes the block allow (1) or not (0) the light to pass through, 126 makes it semi-transparent (only in some Minecraft versions) and 255 will allow all light through
Setting it to 255 made light not pass through, while 0 let it pass
Thank for letting me know :)
I will fix it.
