In Oblivion races had a weight attribute that scaled them across depending on whether they were on orc, elf, or anything in between, in Daggerfall, some races had completely different character art(Orcs for example):
In Skyrim, despite how unique each of the 10 races are proposed to be, and their historical disparity in strength, size, and speed, all of their bodies look exactly the same, and the height differences between them are smaller now then they ever have been in previous games. Orcs are big and burly, High elves tower above the other races, and wood elves are as short as they were in previous installments. This mod diversifies the heights and proportions(Skeleton nif edits using XPMSE skeleton as a base) of all the races in game based on the lore and previous games. Gives all races and genders unique height and body morphs based on lore and abilities.
