Unreal Engine to Steam VR Home


can’t find any solution for my problem:

I have a HTC Vive Pro working with Steam VR.
In Steam it is possible to upload your own Steam VR home environment.
For Example you can export your Blender Project to .obj and upload it to Steam VR, so you can just walk around there.

I tried to export my Unreal Engine Scene into the Steam VR Home but I’m not able to get it working.

Does anyone had success exporting Unreal Engine projects to Steam VR Home?

Can’t find any solution so far…

Thanks in advance
