I plan to make some custom animations (props,ragdolls,facial animation…), and there are a lot of addons when I search for “animations addon”

Could you recommend me the best (and most advanced) of your opinion?

Henry’s Animation Tool, if you wish to stay entirely within Garry’s Mod, or something more advanced

Thank you. That’s exactly what I was looking for. Now I am thinking of going advanced with your posted tutorial…
