OBJ and FBX import crash

Hallo everyone,

i am tying to import some OBJ files into the UE4.10.1 but the engine consumes all my memory (16gb) and after starting to swap it crashes.

The OBJ file is generated with OSM2World 0.2.0 .
I have tried to convert the file to FBX with blender but UE4 crashes also.
I tried it with combine mesh and not combine in UE4.10.1 and UE4.9.2 but always with the same result.

For better debugging purposes I have made a a repo with some additional info and the files.
The screen shot is from another file.

Hello mflender -

I am assuming based on the image you linked to that when you engine crashes you are not seeing the crash reporter. Can you take a look at the following wiki and post your Windows event viewer logs here?

A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums

In addition, I would try to break up the map that you have generated in Blender into several FBXs. That is a general recommendation for any extremely large environment.

Thank You

I added the information you wanted me to. But i wonder if you can re-enact the import error with the OBJ and FBX files i provided. Then you have the error messages kind of first handed.

I have already tried to break the map in smaller chunks with mixed results:
Some of the chunks are working but others don’t and i need all of them to work. It is quite impractical to add all small chunks by hand, is there an automated way of doing so ?

Hello mflender -

I was able to reproduce the crash internally and have entered a bug report as UE-24747. As we investigate a solution I will keep you informed here.

Thank You
