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"

UE4 using more RAM after light build than before

Hi all, i have run into a weird issue concerning the RAM usage of the UE4Editor process.

Build: 4.4.0-2237849

So here is what's happening and i hope you can reproduce it this way:

  1. I start the editor and open my project. The process is using about 2 GB of ram.

  2. I click on Build Light Only and wait until it has finished.

  3. After that the Editor process itself is using about 6 GB of ram.

  4. Everytime i click on Build Light Only all this repeats and the ram usage is increased by another 2 GB.

Specs: i7 4790k, 32gb ram, gtx 680 and a freshly installed win7 64bit.

And here is a screenshot i made to visualize it a little bit better.

Is this a real bug or am i just doing something horribly wrong?

Thank you for having a look.

I actually found an easy way to reproduce this issue.

  1. Create an empty Project and Map.

  2. Add a Stationary Directional Light and default size Lightmass Importance Volume.

  3. Create a Landscape with the following parameters. List item

5.Hit Build Lighting Only.
