the problem is that with optifine installed the electrodes dont render correctly.

i tried it in my moddpack without optifine and it still breaks the rendering .
optifine on its own breaks it but some other mod seems to break it to

I don't have Optifine (I have FoamFix) and I noticed the same thing with copper and gold connectors. I'm not sure if it might be because I don't have IC2 or GT installed (so nothing that makes an EU energy-net

ill try it with ic2

the rendering still doesnt work

The connector render issue is easy, I forgot to remove one check when I made the connectors work without IC2 (the one for registering the models). The OF issue is something completely different, I'll try to get that fixed but can't promise anything.
