Transferring morph targets to clothing, SORTA… Its not perfect, but it does transfer something… You lose some of the detail if you have complex geometry with like dangle things or pockets that are half open… But it will work for say a T-Shirt.
Here is a video I made of me transferring the morph target, maybe someone with more skills than me can show me how to improve this and get the results I am really looking for… I am soaking in all kinds of information at once here, I have been learning blender, animations, rigging, weight painting, Blueprinting and all sorts… This one task alone has prevented me learning anything for about 3 week now as I have been trying to just combat this problem. It only took me about 2 weeks to learn the previous. I know I have wasted my time, which is what disappoints me… I even spend like 48 hours solid designing morph targets without knowing that I couldn’t use them 
Here is the video, maybe it will help someone do some other task.
I should give this quest up and accept its not possible. Feel like just giving up making a game full stop now.
Thanks.
