Hi,

Hey -

Where are you using #define WITH\_SUBSTEPPING 0? Is there any other information you can provide to help me test/reproduce this on my end?

Cheers

Hi ,

1. Download 4.10 sources from the Github
2. Run Setup.bat
3. Run GenerateProjectFiles.bat
4. Open UE4 solution
5. Find Engine\Source\Runtime\Engine\Public\EngineDefines.h file
6. Find #define WITH\_SUBSTEPPING 1, change it to: #define WITH\_SUBSTEPPING 0
7. Try compile the engine

Regards

Hey -

I was able to reproduce the build failure and have entered a bug report for this issue (UE-23805) for further investigation.

Cheers
