What kind of data can be replicated?

I haven’t seen any info on this.
I have a custom object that won’t replicate and always says “NOT supported”.

LogNetPackageMap: Warning: FNetGUIDCache::SupportsObject: B_ItemObject_C /ShooterMaps/Maps/UEDPIE_0_L_Basic.L_Basic:PersistentLevel.B_Item_C_0.B_ItemObject_C_22 NOT Supported.

I assume basic values can and custom objects can’t? Or maybe certain types of values are prohibited?

This object for example contains:

  • boolean
  • int point
  • material interface
  • material interface
  • blueprint class (removed, still unsupported)
  • name
  • integer
  • enum
  • widget (probably not supported?) (removed, still unsupported)
  • float
  • lyra character part (might not be supported?) (removed, still unsupported)

I found some info…
that seems to generally imply things can be replicated if they exist on both client and server (ex. widgets don’t). Actor and component references can if set to replicate, or have the same name on client and server (not sure when they wouldn’t).

“All other UObjects (non actors or components) must come directly from loaded packages”

Not sure what that means?
