Hello all,
Sorry for late reply but I have seen how to fix it.
For some reason gmod will tell you that ulx sbox_maxwire_hydraulics is an invalid or unknown cvar, but it isn't. If you add rcon in fron tof it.
Also in the ulx settings there is no limit for hydraulics, motors, latches, soundemitters and such. They have very weird command name cvars, like sbox maxwire_latchs for wired latches.
Maybe you could add them to the menu. I've seeked for over a week for these commands.
Thanks for all the help
