Hi Thanks for the replies (was expecting an email alert when there was a reply but not the case).
That was one tutorial I had tried following various times and it didn’t work for me, as they skip the part where my issue is, which is what exactly are they bringing into unreal in the first place. They say they have the file in the link below the video, and there is a file, but it is just the mesh- there is no skeleton or bones in it so the file is not very helpful.
Metathesus: You mention it’s a bad idea to do this in 3dsmax - could you say why you say that please, as that might give me a clue as to what a modern better alternative might be 
Thanks!
