Full engine build
- It takes several hundred GB’s of space
- It can take several hours to build
Engine build for games on existing engine versions
This is faster and takes less space.
- Install source, run setup.bat, generate project files.bat
- DO NOT COMPILE FROM UE4.SLN
- Create C++ project from Epic Launcher in same version
- Switch the project to the source build (should be available via uproject’s switch version function)
- Build from your game’s sln file
- Build the project not solution, as building solution will sometimes build all the extra crap you don’t need, which means you won’t save any time
