I kept watching tutorials on how to make a custom ped, and so I imported the ig_bankman model it parts keep saying fake bones. How do I fix this? I am using 3ds Max 2022 and GIMS Evo.

UPDATE:
I think it was an export problem because when I try to export the original ped from 3ds to gta, I tried loading the original ped and still crashed. Anyone know what to do?

So I got 3ds max for a free trial and installed GIMS EVO. I decided to make my own ped. This is my first time using 3ds max. I wanted to change my peds head so I imported the two peds but I decided to import one of peds head only. i deleted the head of the other ped and place the new head to the body. once I was finished, I extracted the files to openIV. When I try to load in my ped the game crashes. I thought it was just my game so I load back in. I load in different models to see if it was just my game but it wasnt because all of the other models work instead of my newly edited one. Can someone help me in on this?
