[Blender] Clothing ignores Character mesh


I have imported a character from Blender to UE4 with no problems so far, and I wanted to use the Clothing Tool of UE4 to make my scarf a cloth asset. But the scarf goes through my character mesh as you can see in this picture :

I have checked everything about dimensions. In Blender, I’m using the metric unit and everything seems alright, even after the export. I have also note that the approx size of my scarf changes after using the clothing tool with crazy dimensions. Before being a cloth asset it was clean with correct dimensions…

Any ideas to correct this ? Thank you for your attention !
