Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

crash on startup Attempting to replace an object that hasn't been fully loaded

Hi in my project every time i create a BlueprintClass child of a certain blueprint i get this "crash crash on startup Attempting to replace an object that hasn't been fully loaded"

But i only get that after closing the editor and trying to re-open it.

If don't close the project i can keep coding and doing stuff the crash never occur. It only happens on reload.

I found this similar issue -> https://issues.unrealengine.com/issue/UE-40042

My project setup is kind like this: I have my BlueprintParent, it has a bunch of things (I know its bad), very large blueprint. And this BlueprintParent may have children of the same type as BlueprintParent or not and also may have proceduralMesh.

I'm trying to make children from this BlueprintParent with no success. Debuging i know that "crash on startup Attempting to replace an object that hasn't been fully loaded" is occuring in a proceduralMesh part of the code.

I'm Using 4.15, when i delete my BlueprintChild direct from the project folders it works fine again.

What do you guys need for more testing? Or maybe a work around, i have seen this https://answers.unrealengine.com/questions/559543/crash-attempting-to-replace-an-object-that-hasnt-b-1.html

But cant say if this is going to work.

Thanks, see ya guys.
