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"

Massive perofrmance drop in 4.15

Hello, I created an open world map in 4.13 version and I go around 100 fps. There is a lot of foliage and when I opened the same project in 4.15, I get like 6 fps... Changing the graphics settings does not help at all..

Product Version: UE 4.15

you might have some warnings / errors if you just converted to 4.15 (check materials etc). These could cause the massive fps drop

So I found out that some of the static meshes I used for foliage were causing it. But when I removed the materials from them it did not help. What should I do because I want to use these static meshes
