See UE-38525. Occurs when there is no material assigned to the model in your DCC tools
Using the test asset provide the editor will crash when changing the import to Skeletal Mesh.
This is a regression from 4.13 where this could be imported as Skeletal Mesh without issue. In 4.14 and 4.15 the Editor will cause a crash.
Working: 4.13 Binary CL-3172292
Broken: 4.14 Binary CL-3195953
Broken: 4.15 Dev-Rendering CL-3201999
1. Use the attached Test Asset
2. On the Import Options set it to Skeletal Mesh
3. Click Import
