All previous (old) values to the left were based on what is used in the game for the official Maxis file. All current (new) values to the right are based on what you’re using in this new clothing mesh.
We begin by reading the list from top to bottom. You count the rows starting with the first line representing “0”, and adding 1 more for each line. You add numbers using the hexadecimal numbering system (0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F).
For example, 9 + 1 = A, not 10. Or, F + 1 = 10. Or 89 + 3 = 8C. Etc.
