i dont know how to make animations in ue4 can you make it in engine like unity or you have to make it in blender,max etc?
Double click on your skeletal mesh - in persona you have to click on the record button - move the bones - give it a name and save it. It’s recommended to use a program like blender, 3ds max,… because you will be faster + it’s easier and better to create animations
so in theory i can make one?
Yep, with the steps that I posted above
