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"

Lods doesnt affect performace.

I have a bunch of meshes with LODs. I can see, that LODs working well in scene and editor, but performance not improving, no matter, LODs imported or not. Maybe I missed something?

Just using LODs for meshes won't improve performance. LODs are usful for:

  1. Cutting of triangles, when you have big vistats with a lot of meshes.

  2. Cutting of materials, if you have big vistast. Far LODs usually don't nee more than one, very simple (one texture) material.

If you have performance bottleneck I recommend checking this link:

https://docs.unrealengine.com/latest/INT/Engine/Rendering/PerformanceProfiling/GPU/index.html

As well as click on arrow (top left corner of Viewport) and there is Stats, submenu, and Advanced. There are various profiling stats like SceneRendering, ShadowsRendering, etc.
