  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
