Fatal error: [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/Core/Private/GenericPlatform/GenericPlatformMemory.cpp] [Line: 197] Ran out of memory allocating 7447602000 bytes with alignment 0
Apparently it’s an insufficient RAM memory issue. You’re gonna need more ram or optimize the asset so your RAM doesn’t get fully saturated while importing.
I had the same issue importing a tree asset I’m building. I reduced the polycount and it’s working now. I’m also gonna try not having other programs opened while importing, maybe I have enough RAM (32 GB), but a % of it may be being used with Chrome and SpeedTrees open at the same time.
But the byte count in your error message (7447602000 bytes) is equivalent to 7.44 GB, which is quite a lot of additional RAM being needed to finish importing the character. In my case, I’m only needing 0.88 GB more of RAM memory.
