Unreal Engine Issues and Bug Tracker (UE-42334)

Description

Crash using Import Commandlet on FBX that gets "Bones are too small" error when imported manually

Error from manual import:

Warning The bone size is too small to create Physics Asset 'ButterflyValve_0_PhysicsAsset' from Skeletal Mesh 'ButterflyValve_0'. You will have to create physics asset manually.

Error message:

Fatal error: [Link Removed] [Line: 553]
Attempted to create a package with name containing double slashes. PackageName: /Game/Test_ImportCommandlet//ButterflyValve_0

Most recent user affected CL: 3249277

Logs: Attached

Steps to Reproduce

Download the attached json and fbx files

Create a batch file with the following:

$UE4EDITOR-CMD.EXE_FILEPATH $UE_PROJECTFILE -run=ImportAssets -AllowCommandletRendering -source=$FBX_FILEPATH -dest=Test_ImportCommandlet\ -importsettings=$SETTINGS_JSONFILE -replaceexisting

3) Attempt to run the batch file

Result: Crash
Expected: Imports successfully, just without the Physics Asset (like it does when importing manually)
