Acronym is an arbitrary choice
It is internally called ShaderParamAnim, indeed with no U inside. I tried to find a meaning for the U anywhere, but it seems to have been an arbitrary choice to make it differentiate from other structures. - Ray Koopa (talk) 15:30, 28 May 2017 (UTC)
- How did you find that? All I know is that the three different types of FSHU is specified. But I don't think they just decide to put a letter in the end, it should have a meaning.
