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"

Widget Fatal Error - Happens during Packaging and after Opening the Project

Hello everyone,

in my Project (Blueprints only) i want to use widgets. I created 3 different from the widget blueprint in the user interface section. I added content and animations.

In the first time of creating these things without closing the unrael engine, everything is working fine in the editor viewport. However, if i want to package the project or i reopen the project in the unreal engine, every time i get fatal errors.

In the widget i have to change (adding a variable, text, button or anything else) and everything appears and can be compiled, however thats no solution because the problems from above in launching and packaging still happen.

Here are the Errors from the OutputLog:

  • LogBlueprint: Warning: [Compiler BP_Origin_Widget_appearing_AreaNaming] Get : 'Fade' variable not found. Base class was probably changed. /Game/Blueprints/Interaction/Text/BP_Origin_Widget_appearing_AreaNaming.BP_Origin_Widget_appearing_AreaNaming

Here are some Pictures from one Widget:

Here is the Designer, the Fade Animation is shown correctly also in the animation graph alt text

Here you see the Graph and the missing fade as well the image alt text

After changing something (here i added a variable but not compiled yet), everything shows up again alt text

Thats how i add the Widget to the Viewport: alt text

The Base class of the widgets have not be changed and the Data shows up in the explorer in the correct place with the correct name. Creating a new Widget will cause the same errors and I also tried to migrate the complete project into a new one but the problem was the same.

I could eliminate the possibility of producing these errors from other blueprint. After i disconnected the widgets from the Blueprints to avoid running them i could package the game without any problems. Does someone knows this kind of Problem? Is there some solution or do i have to do this project without widgets?

  • I have also added a clean Widget Blueprint without any changes, here are the Errors of this situation:
