Softimage to UE4 - FBX import failed, want to know why

Hi David, thanks for the reply

No, I’m using the FBX within Softimage 2013 ( not sure right now which version, but should be 2013 release ), no standalone converter.
If I remember correctly the 2015 FBX plugin ( for Maya and others ) doesn’t work very well with UE4, is that right?
