How can I resolve the error "In Powerup: Found more than one edit/visibility specifier (VisibleDefaultsOnly), only one is allowed"?

VisibleDefaultsOnly is EditDefaultsOnly are specifiers which set access property in property editor, you can’t use both of them is same time, you need to pick one of them.

  • Visible* = Read-only
  • Edit* = Read-Write

In other words you trying to make your property Read-Only and Read-Write in same time :stuck_out_tongue: Considering you trying to use “EditDefaultsOnly” means you just need this one, so remove “VisibleDefaultsOnly”
