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"

Disabling LPV plugin crashes Editor after Restart

I set up a blank project, tweaking project settings then went to plugins to disable what platform/project doesn't require. After restarting Editor got this crash. So, can't load project and now I have to create a new one.

For whatever reason I got 3 consecutive crashes (clicked Ok on first one, then got 2 more same Error pop up messages).

That wasn't an issue with 4.10.4

Hi motorsep,

I was unable to reproduce this crash. Can you provide more specific steps like these I used to try and reproduce the issue:

  1. In UE4.11 preview 7 create a new blank project without Starter Content

  2. Choose File>Package Project>Supported Platforms

  3. Deselect all platforms except "Windows" (*IMPORTANT: list all platforms you have selected)

  4. Save Project

  5. Close Project

  6. Close Launcher

  7. Restart Launcher

  8. Launch Test project RESULT: No crash EXPECTED: Editor to crash upon launch of test project.

I did better - recorded a video :)


So when I do all that, crash happens whether I have all platforms enabled or all disabled except Android (which is my target platform).

Addendum: After enabling the Light Propagation Volume per instructions on the following link, retried steps above:


Still unable to reproduce crash.

Sure thing, no problem!

I just want to confirm 4.11p8 has the same issue.
