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"

ca. 1300 static meshes (spheres) - optimizing rendering

Hey guys,

I am building a fairly simple prototype that basically only spawns 1300 spheres from a csv-sheet. The spheres are blueprints with some logic applied to them. Mostly they have force applied to them. The force pulls them to a gravity-center where they create a big "blob".

When I am standing some meters away it's all fine. But when I go closer it starts to lag like crazy. I was thinking it has to do with higher quality rendering when I am closer - opposed to less quality when I am standing further away.

My question: what are the options I have to lower the quality of the rendering for the spheres to see whether the visual quality is what causes the performance-drop?

thanks alot in advance!

Note: I am new to UE4 and making my first prototype, so even obvious answers might help!

Product Version: UE 4.15

Press F2 in game, this will switch to unlit render, which is simple as possible.

To understand where it lags use ptofiling.
