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"

Unreal Engine freezes when i load a foliage type

When i drag a foliage type into the foliage type drag and drop thing the unreal editor freezes! It's really annoying! My computer also gets very hot when the unreal editor freezes, like 80 degrees celsius (176 degrees fahrenheit).

Here are some examples: https://youtu.be/2brId_Bx4dM https://youtu.be/eHRBwn3zMNU

(using Unreal Engine 4.12.3)

Product Version: UE 4.12

Hey GamerOrigineel,

If my memory serves correct, the assets you are attempting to load in both video examples come from the Kite Demo/Open World Demo project. If that is the case, and you migrated them from a separate project, they need to be initialized and loaded into memory before you can use them.

This freezing does not occur with a simple cube mesh when you click and drag it into the Foliage Mode, so this does not have to do with the foliage mode itself. The assets you are opening are very high poly and use large textures. Your computer needs to finish processing the assets, which is happening during the freeze. You will see the engine is still running processes when the freeze occurs. I would try waiting for at least 5 minutes before trying to close the editor.

Let me know if you have further questions or need additional assistance.

I have the same issues, nowadays, yes using the Kite demo. I understand the need to load these high quality assets... But, can I let them load all at once as its own thing? So it doesn't freeze me when I select and add some as Foliage. Like right-click menu option over a folder in the content menu.

EDIT: Seems like Validate Assets in Folder do this, but I don't really know the technical correctness of that.
