okay, im getting red everywhere.

i know how to fix it, by adding reflection probes and
compiling reflections

but.. when i run that step

opens game, tries to load map and after awhile
error:

script compile error
(see console for details)
cannot switch on undefined

the compiler console stays blank
and the ingame console shows nothing at all..

i have a .gsc , copy & pasted
and a .arena
any other scripts i need??
do i need .fx even if i dont put any fx in my map??
