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.

Yeah, right. As I can see in ProfileGPU - its not LODs. Thanks for link.
