So do you need to do those console commands? Cuz if you do i'm probably just going to go to my corner and cry.
Nope, I've included a tool, the "Wire Wand", so you can mess around with them without needing the console.
I just ran a test to see how much more efficient using particles to render the wires instead. I found that particles give me average 132.3 FPS compared to average 75.9 FPS for static shapes, so I think I am going to make it use particles.
Particles also give a little more freedom for the appearance of wires. The thing I don't like about them is that they are not visible through transparent bricks. However, with that much of a performance difference I think I'll have to use them.
