Macro Definition Documentation

UE_ALLOW_DISABLE_CANCELLING

#define UE_ALLOW_DISABLE_CANCELLING   1 && !UE_BUILD_SHIPPING

When enabled it is possible to disable request cancellation via the cvar 'ias.EnableCancelation'

UE_ENABLE_IAS_TESTING

#define UE_ENABLE_IAS_TESTING   0 && !UE_BUILD_SHIPPING

When enabled we will run some limited testing on start up for issues that are hard to reproduce with normal gameplay
