Macro Definition Documentation

UE_ENABLE_BULKDATA_RANGE_TEST

#define UE_ENABLE_BULKDATA_RANGE_TEST   0

When enabled calls to FChunkReadFileHandle::ReadRequest will validate that the request is within the bulkdata payload bounds. Currently disabled as FFileCache still uses the handle to represent the entire .ubulk file rather than the specific bulkdata payload.
