Here we go xD the left and right hand lightning xD Make separate segments with only the origins changed. Like this:
Electricity
{
name Lefthand
spawnflags org2OnTrace
origin 0 -10 -1 0 -7 1
...
}
Electricity
{
name Righthand
spawnflags org2OnTrace
origin 0 10 1 0 7 1
...
}
Change the origin values depending on how far apart the hands are.
Note that because of this spawnflag, both bolts will end on the same location. If you don't want that, you need to set a origin2.
