  To  make  building  spawn  work ,  you  need  to  configure  the  data  in  DT_Objects_info   (/Content/CA_Code/Blueprints/Wiki/DT_Objects_info.uasset)  Specifically  for  spawning,  a  Class  reference  needs  to  be  specified.  If  it's  not  
specified,
 
the
 
code
 
won't
 
know
 
what
 
to
 
spawn,
 
won't
 
know
 
the
 
price,
 
and
 
so
 
on
  If  the  class  is  invalid,  hovering  over  the  icon  will  print  a  message  to  the  log
