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"

UE crashes as soon as I add assets (mesh/materials)

Hi everyone,

Super excited to start playing around in UE. I download and install, add the Open World Demo Collection to my project, ready to place meshes, materials and what have you, but as soon as I do UE crashes. It freezes and I cannot click or do anything except force quitting it.

Tried looking online and here on the forums but no luck. Anyone have any ideas? I did reinstall twice, added the package twice, rebooted my PC twice.

Appreciate any help!


[EDIT] Actually it crashes/freezes whenever I even click one of the assets. Left- or righclicks.

Product Version: UE 4.10

Hi Icebergplz,

This isn't a crash or a bug with the editor. The content in question is meant for high-end machines. The content's description covers this as well that it can take upwards of an hour to open for the first time. Depending on your system specs this can take even longer.

The reason this takes the time it does is because these assets have very large textures (8192x8192) and complex geometry. On the first open the DerivedDataCache has to be written so they can be opened more quickly with subsequent use.

You can read up on this here: https://docs.unrealengine.com/latest/INT/Engine/Basics/DerivedDataCache/index.html

I hope this helps explain why you're seeing this on your end.

Hi Tim, thank you for your answer.

All right, then I think I got it. I appreciate you giving me the link, I'll check it out.

What could be a nice feature in the future is to let the user see a loading bar/progress screen as the assets load so it won't confuse us (me) that much.

Once again, thanks.

Regards ice
