The mod without FOMOD installer for those who prefer manual installations.

Uses Dynamic Animation Replacer. See description. Compatible with Sexy Random Idles (https://www.nexusmods.com/skyrimspecialedition/mods/42332)

FIXED VERSION: now each animation (including vanilla or your replacer) should have 25% chance of being used.
