It's a addon,and there is no tile Entity.actually,all is done by a new block called PCB,which,when placed under the redstonewire,will reshape it's pointing according to the PCB's metadata.
So, this mod worn't lag the game too much,or maybe boost a little bit since redstonewire pointing is not calculated on PCB.
PCB is create when Rendering potash on stone and...something I'm not sure.maybe something redstone is scare of, so they won't touch the rest part,Anyway,we well see it in the release
PCB current looking:
the PCB it self could be an Aesthetic block with proper texture I think
as you can see, the redstonewire runs on the direction the PCB block is pointing to
Finally, I decide to adopt etching technique to create PCB. you'll need fermentedSpiderEye as acid, potash as protection, and stone as base material in an stoked Stewing Pot.
I still need some testing and it should be ok in a few days,if noting goes wrong.
