That definitely looks like a bug, could you post on https://answers.unrealengine.com/ and supply your fbx/max models so we can repro and track the bug?
OK, it's all been decided. Theyve found our man: http://www.thisislondon.co.uk/insiders/guides/articles/14483616?source=Metro /goes off to gather reference.
It should do, yes. I've tested it with 801 and 901. Warren was having issues with it in 801 (that I can't repro here) so any issues there let me know :)
