I finally got the 3rd person swimming animations to work in 1st person!
Thanks to Hrnchamd for showing me where to hex edit the MW.exe to keep the game from blocking them.
Hrnchamd is a wizard!
We are both testing a bit to make sure there isn't any unforeseen weirdness from disabling that bit.
Hopefully the switch will be in the next MCP release & then I will release The mod.
