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"

No Destructible Meshes in 4.18.


in any version since 4.15. I got the problem that, whenever I package a game, which succeeds, the packaged game immediately crashes (got an open question regarding this problem, but nobody's taking any notice so far...)

Now I tried version 4.18. and it destroys the whole project as it doesn't recognize any destructible meshes anymore (can't create new destructible meshes either) . How do I fix that issue?

Found the same issue. It looks like now this is a plugin (Apex), so if you enable it, everything should work as before.

How do you enable the plugin if you can't open the editor?

You need to edit the uplugin file at: :\Program Files\Epic Games\UE_4.18\Engine\Plugins\Runtime\ApexDestruction\ApexDestruction.uplugin

And change EnabledByDefault to true.

As noted in other answers, this was moved to the Apex plugin which is not loaded by default, even if you already have destructible meshes and are migrating to 4.18. You can enable it by opening the editor, going to Edit > Plugins, and under the Physics section, checking the box for the Apex Destruction plugin.

Or, if you can't open the editor, edit your uproject file and add it to the plugin list, like so:

     "FileVersion": 3,
     "EngineAssociation": "4.18",
     "Category": "",
     "Description": "",
     "Plugins": [
             "Name": "ApexDestruction",
             "Enabled": true
