In this page, you can adjust some preferences that affect performance of processing C++ code.

Index Unreal Engine source files

Clear this checkbox to skip indexing of the Unreal engine code. Normally you want to do this if you notice any performance degradation when developing your game.

When the indexing is enabled, you will have a number of features. For example, use any symbols from the engine and ReSharper will automatically add missing #includes, or find usages of engine classes — for example, TArray<T>— in the engine's code and study how they are used there.

If the indexing is disabled, ReSharper will still index header file names, which is very fast but it will let you have code completion for includes, for example, #include <unreal/SomeClassFromUnreal.h>. Once you include a header, its code will be indexed automatically, so you will have code completion and analysis for symbols from the included header.

Index third party code Clear this checkbox if you want to skip indexing source files under the ThirdParty folder of the engine.
Index plugins Clear this checkbox if you want to skip indexing source files under the Plugins folder of the engine.
Enable background indexing of Unreal Engine source files ReSharper indexes the engine code in the background by default, so that you can start working with your game logic code long before the engine code is fully processed. Turning off background indexing will result in a faster but more intrusive initial indexing.
Use Unreal Engine project model (starting from 4.24) Reading .uproject and other UE-specific project files allows ReSharper to better understand plugin and module references, and to suggest only available and applicable items in the #include and code completion lists.
Regenerate project properties on configuration change The Unreal Engine project model information is essential when you have different settings for various build configurations, targets, and platforms. With enabled experimental support, you can switch between configurations and be sure ReSharper will work properly for all of them.
Treat Unreal Engine symbols as non-project in Search Everywhere/Go To Matching symbols from the engine project will only be shown when no symbols are found in the game projects.
