I used pose to pose and straight ahead animation to combine walking, turning and looking, running and jumping. It was challenging to make it look seamless.
cool shot, nice effect!
Your animation is a bit stiff and you could add some more weight to your character, especially in the pelvis with some movements side to side and up and down when he is getting ready to jump.
But it’s a really cool project
Seamless looks is not that hard to achieve in my opinion. Make it look natural, like in “not stiff”, is much harder. Yours is okay in the second half but very unnatural at the start. Cool explosion effect though!
