I made 4 versions.

The first one may look pretty bad. But it actually lines up pretty well on the cables. The other 3 do not line up at all.

Here is my block_cable.png

These textures are very hard to do... So most of it looks plain.
If someone wants to redo the uninsulated wire. Then please do.

I wish each side of the cables used there own texture. I hate how all sides share the same texture. Makes things almost impossible.

Edit: i played around with them in my world and i quite like them both the uninsulated and insulated cables

Hmm, interesting creations. I think they may need a tweak.

I really don't like the cables. In game they look like a pin-stripe suit.

My attempt at copper cables:

Though, you can see the issue with the sides. A lot of the time they line up but sometimes they don't.

Also the middle where they turn goes very fuzzy, but I must say it's a lot better to look at then totally straight lines.

I like cadens,

I wanted to do something like that. I just did not know how to line up the cables properly.
