Metahuman custom Hair only few strands showing when binded to head

[PaolaOCR]

Hello

I made some custom hair for my metahuman, I added them as new groom in the blueprint and they look perfect and in the correct position but then when I create the binding most of them disappear and only very few strands showing instead of the full version.

I also changed the setting to “inclusive” in the progect settings because before they were completely disappearing. But this didn’t solve the problem completely.

This is what it looks like:

Any help would be very appreciated

I have been doing some tests and looks like if I use a very low density in the Xgen options in Maya, and then I bring it in Unreal and bind it to the head, it works.

Instead as soon as I add more density to have a bit more details, once I bind the groom on the head most of them disappear (looks like only the strands where the guides are stay visible).

No clue how to solve this atm.
