Is it possible with xml to remove the squiglty line that shows an object is connected to power? I am the author of the ceiling lights mod and would rather not have to see that because it makes no sense to have a power cord connected to a ceiling light.
That's a core engine effect and is based purely on if the power trader is in the same cell as it's parent power transmitter. The only way to "get rid of it" would be the replace the texture for the wire with a "blank" texture but, that would be a global change and effect all buildings which draw power.
