I saw a develop tutorial making a running animation with only 2 frames and achieved very smooth result with interpolation. What i don’t understand is, shouldn’t it be 4 frames cause each foot need 2 frames? How to use left foot forward frame to the right foot? And I don’t know whether the interpolation process should be done in a third party software, such as Blender, or could it be done within UE so that I just need to import 2 frames from the animation software.
