I'm sculpting a Custom Body For Crusader Kings 3 and I'm a bit stuck.

[TakeshiBellpepper]

Hey guys! I'm working on Mastiyya/Hathor mod, I'm in the midst of sculpting a custom body for the mod! (in the future, custom erotic egyptian underwear, and better pregnancy bodies) I have a big issue though, I have the body sculpted and exported into the game...

but it's looks quite jagged in some areas, but see the hip? You CAN SEE THE SCULPT OMFGGG.

 

Where I am lost: I'm using Blender, PDX tools, all I did was grab the body from in game, and resculpt it and re-apply the UV mesh, and then I made a copy of the asset. Armature is untouched! 

 

Are there any reasons as to what could be causing this? I'm new to blender, only a week in, so I'm still learning the ropes here.

 

Thank you all for taking the time to read.
