Custom AnimGraphNode with packaged game

Hi all,

I have implemented some custom AnimNodes which are implemented in a runtime plugin module and corresponding AnimGraphNodes implemented in the editor module for the plugin. However, when I try to run a packaged game which was packaged using just the binaries of the plugin I get the following error:

LogProperty:Error: Struct type unknown for property 'StructProperty /Game/Mannequin/Animations/ThirdPerson_AnimBP.ThirdPerson_AnimBP_C:AnimGraphNode_Custom_4F15357F4632CE8636A0988C7AB3B9C5'; perhaps the USTRUCT() was renamed or deleted?

What is the correct way for packaging in this situation ?

This error does not occur if I am trying to package from a project which sees the code of the plugin as well …

Thanks !



Could you please upload your full error output log as a .txt file? It looks as though you need to verify that the USTRUCT is entered correctly or hasn’t been modified previously.

  • It would be extremely helpful if you could tell me exactly how you’re packaging your project.
  • Show me how the USTRUCT is set up as well as how it’s referenced in the project. Screenshots are greatly appreciated.

I have somehow mysteriously fixed the bug. I will need to figure out what exactly caused it to go away, but I am happy to mark this issue as resolved. I will post here if and when I figure out what exactly was causing the bug or if it resurfaces. Thanks for your help !
