Description:
Importing a binary FBX 7.4 file that was exported in Blender, which contains at least one animation makes the editor hang at 75% of the progress bar for about 1 to 2 seconds before it crashes. That didn’t happen with Unreal Engine 4.12.5.
Exporting from Blender as FBX ASCII 6.1 doesn’t cause a crash upon importing into the unreal editor, but doesn’t import the animation.
Caveat: At a first glance, the console output suggests the issue might be happening during mesh triangulation. However, pre-triangulated meshes crash as well, with the last operation instead being related to material processing in that case. It’s possible the console output might be a bit misleading in that regard.
