all added animations would not work, only vanilla animations would work (running, jumping, swinging a weapon, etc.). when trying them they would not work, my character would just stand there in a T-pose. i did the normal steps: i enabled the mods that needed FNIS in MO, ran FNIS and updated the FNIS Behavior (with GENDER and SKELETON patches), installed the file's from the Overwrite folder in MO, enabled them and tried them. I recently installed a couple of mods that use FNIS (because some are not appropriate i shall not list them here, more info below).
