Hi, i was using a Riften deck piece for one of my projects and found that there is a big invisible gap where the player walks, making it impossible to use, but i really need it. If your in the creation kit load up a RTMjollDeck01 and the gap is on the wide edge opposite side of the railing. I don't know much about editing nif's meshes but if someone can help i have the nif of that piece extracted for possible fixing if anyone can.

Maybe you could use NifUtilsSuite and make new collision for the mesh.

This page has a link to NifUtilsSuite and info on how to use it.

I added the missing collision. See if it works for you (did for me):

Awesome! Good as new, thanks a lot
