You have 30 seconds to explain why IC2 cables still do not support it, like Applied Energistics, Thermal Expansion and a tonn of other mods do.
You have 30 seconds to explain why i not BAN you for this post ?
sorry you had your 30 seconds
FMP (forge multi part) is buggy (i've had problems with them when "playing" Agrarian skies) and many mods stopped supporting it, including Applied Energistics (see AE2 facades).
You got IC2 Construction Foam + obscurator for your hiding purposes, learn to use them.
IC2 will NOT support FMP.
