do you hold down the key for playback

Yes

there's no errors in the console, and you do happen to have things recorded for animation in the first place?

No errors, if "things" are meaning addons then only ragdoll mover

i mean if you recorded any entities to be animated with smh, mostly. can't playback stuff if there's nothing to playback

Oh then, no, only ragdoll

does the ragdoll change its position when you move the playhead around the timeline? mostly between 2 keyframes it would have recorded

Yes, it changes

and putting playhead on first keyframe there and holding down the playback bind doesn't do anything? what if you also enter +smh_playback in console? to stop it you would need to enter -smh_playback btw

still dont working

even when you enter command in the console?

yes, idk what to do with it. theoretically this addon can conflict with other or not?

shrug. i'd say perhaps issue was in don't animate physbones option, but when you move playhead stuff does get positioned and all. technically you can try disabling all other addons except for smh and check again

okay, thanks, i will write later if this will help

Well, idk why but it works now.
I didn`t do anything, well... just bug maybe
