“Better Beast Races” cleans up the blocky angles on the heads, mouths, hands and bodies of Skyrim’s beast races, specifically the reptilian Argonians and cat-like Khajiit. Mod creator Xenius blames the “angular shapes” on “compressed object space normal maps,” probably due to the game’s space-constrained console roots. The latest version (v2) adds “more detailed diffuse and specular maps.”
