Rider and Unreal C++


I noticed while building Unreal project that the compiler compile files like 1/95, 2/95 ...etc. I dont know does it use CPU threads in compiling ? if no can be done to get faster compile ?

Hi William,

Rider uses Unreal Engine infrastructure to build projects. If you want to adjust number of processes UBT uses to build your project, you can try using different ProcessorCountMultiplier and MaxProcessorCount.


You can also try using FastBuild if you want to reduce build times. You might find these articles helpful: 1, 2. Please note that currently Rider will not be able to build FastBuild-based projects due to the issue RIDER-67391.
