Geotiff import error cesium UE4

Hi, I keep trying to import a geotiff file but it keeps crashing UE4 with the error:

Fatal error: [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/Core/Private/GenericPlatform/GenericPlatformMemory.cpp] [Line: 197] Ran out of memory allocating 18446744072087848704 bytes with alignment 0

its not running out of RAM, and I can load larger laz files in that this problem file.
Is the file at fault or could it be a bug?

Hi @UnrealVistas,

Could you post the steps you took to load the geotiff file? In addition, if you are able to provide the file in question, that would be helpful so that we can get to the bottom of this.

I’m not actually sure if we specifically support loading Geotiffs directly - I’ll find out.
