In the current version of the mod(1.3.2-12), ME cables and a lot of other Transparent blocks(lever,vanilla glass,etc) blocks the light from the floodlight.
Could you adjust the light blocking mechanics to allow the floodlight to pierce through the transparent blocks?(don't remove old mechanics, make them configurable)
And also add a type of floodlight that is expensiver(may need nickel or platinum to craft if present or diamond if not) to make but its light can pierce through all blocks?
No need to make the blocks pierced to glow. Just make the air blocks behind the pierced blocks glow.
