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"

100+ strange texture files appeared in level folder (4.8.3)

Hi everyone

I'm posting this after a thorough search for a similar post, but it seems like no one has experienced a similar issue yet.

So, lately we've been experiencing a very peculiar problem concerning some of our level files. What you can see in this first screenshot is what happened to my "Maps" folder after tweaking our lighting a little bit (adding fog, tweaking bloom and directional light) inside the editor.

All those texture files appeared first when I saved my level. My first move was then to delete all of them, resulting in losing my level.

Having done that, I reverted after deleting the "Intermediate" and "Saved" folders from the trunk, hoping that would fix it. When I came back into the editor, the texture files were gone, but as soon as I saved the level, the texture files reappeared (even though all our lighting tweaks were gone !).

Here is what is displayed when I check any of those texture files inside the reference viewer : alt text

What is actually referenced is my level file

Furthermore, those files don't appear in my browser and will automatically get checked in and out whenever I wheck in/out my level file : alt text

I really can't understand the dependence between those files and my level. Apart from that, everything looks fine and works as before. I'm really looking forward to any help/suggestions from your part !

Hi there, I also experienced this for the first time today. i found a solution by first deleting all the textures (while having the map open in the viewport so you're able to save it again shortly after). I then went to project settings-->rendering and unticked the Generate Landscape Real-Time GI Data box. Saving the map right after didn't generate those textures and everything works perfectly. The strange thing is that I never ticked that box in the first place? Messing around with the lighting probably triggered it. Cheers!

Hey @Matlink ! Thanks for the answer !

I forgot to tag the issue as resolved. I found the answer to the problem in this thread but thank you anyway ! (That would've helped me a lot if I hadn't found it). Seems like this issue causes a lot of crashes too (moving the level around the content browser for instance).

That's the thread btw : https://answers.unrealengine.com/questions/237692/256-landscape-textures-show-up-in-maps-folder-why.html
