Hot Reload makes changed C++ classes unknown

Development Programming & Scripting

Hi .

  • 4.6.1
  • simple changes such as adding variables in such way that remapping of class at hot reload is necessary!!
  • No, it happens on HotReload. Closing editor, compile from VS and open Editor again will make the types known again.

I very much think this issue is related to 2 other posts I have posted earlier to which you have not answered on my new comments.

HotReload seems to change types such that ‘many’ things go wrong:

  • Serialize to file with PerObjectCongfig
  • Custom components in blueprints appear with different name, eg ComponentName_HOTRELOADED_0 etc.
  • Ambiguous warnings are posted from Unreal at runtime where it shows the original name + ComponentName_HOTRELOADED_XXX etc.
  • Cast in code fails

See also my other posts on this. This is probably all very much related to hotReload changing the actual type in memory.
