Importing in UE4 leg issues

I am having a issue with importing a model in UE4…It looks good in blender with her legs apart but when I import into UE4 her knees are together…Arms are wrong also…Any ideas if I might be doing something wrong?

Please see pics below

Thanks in advance guys…

Are you certain you have applied the location / rotation of the bones in blender?

I just messaged the guy that is making this for me…Looking at the pictures it looks like W is not applied…whatever W is :)…Thanks for the info Imma get hime to apply it and resend it to me…

Do you know what W rotartion is? and how to apply it? he is having issues applying it and if he changes it to 0 it puts her arms behind her head…

In pose mode, have him go to pose>Apply>Apply pose as Rest position

See if that works.

It didn’t help…He said he weighted the dress…could that be the issue? Also wanted to say thank you for helping. He joined a blender group and is working with them guys and he has a few ideas now…If you want you can close this post or set it answered I think we have a idea on what to do.
