I'd love to hear any crits about it. This horse is what I've been working in my internship. As a side note, the horse isn't going to rear up high and long enough for a kick. Though once I finish this I'll do one with a kick. It might seem robotic because I'm using linear tangents. I'm more concerned how the timing is... too fast, slow on certain parts? etc. I'll post one with the tangents smoothed later today.

the horse needs to stay up longer in the animation, and smooth out those tangents make him look natural. have him kick while he's up in his rearing too.

keep going

Yeah, he'll probably stay up a bit longer once I smooth the tangents. Also forgot to mention that it's not that high of a rear up, so I won't have him kick. I did have a kick in my previous animation but I scrapped that and started this new one. I'll probably try adding a kick once I finish this one.

Thanks for the quick reply :)

Yes, definitely need to have the horse stay up longer (perhaps as long as the entire piece is so far), maybe kick at the air with the front hooves. I think you need more anticipation before the rear up. I'd add lots more secondary animation on the head and tail, both before and after.

- made the pelvis use spline tangents and tweaked it so the horse stays in the air longer, I think I can go for bit more.
- had the shoulders show more of an impact when the front legs hit the ground.
- tried to make the back legs exert more muscle.

I tried to play a little with the y translate on the pelvis but I don't think it's too much. The horse looks like he's humping the air now. I'll probably add more frames before and after the rearing. I'm only using 45 frames on this. I'll concentrate the those rear legs on my next update too. I'm going to animate the tail when I'm done with the body since the motion of the tail depends on the body. It would suck if I animate the tail and I make a big change to the body so I'd have to change the tail, you know?

keep him up in the air long enough to do three kicks a right left right combo, also you might want to slow down his descent to the ground from his reared back standing position. it's all alittle too fast still

- extended total frames to 60

How's the speed of him going up and down?

Arrrgh, I should be working on my essay :p

the speed is better but he needs slightly more hangtime, have you ever seen a horse rearing, im lucky enough to have a dad who rides so i've seen one in real life. i would suggest renting a horse movie, preferably a western or a movie about a wild horse like black stallion. to get a reference for horses rearing. also it doesn't look natural cuz there's no kicking.

I've been using this as my main reference. (Click here ( for a colored version.)
I have a bunch of other movies but this is the closest one to what I want. This ( one is close too.

The hang time and duration of the action is better. I thinkthis is really all about weight. Make it look and feel like the horse has a lot of weight that it must move around.

1) It takes effort to kick off the ground, make it look like that. ie... do a strong anticipation. Also, you have the body still lowering in the front when the front hooves are off the ground.
2) Hang time suggests weight and gives drama which is why it needs to be long.
3) The decent to earth is too slow, too floaty. Dump it back to earth fast, make the hooves hit hard, then cushion the body at the bottom.
4) Secondary action in the head, the neck, the tail also suggests weight.

Reference is great. Very helpful, but often you need to exaggerate the action to make it look realistic, to sell the action. Better yet is to act out the action yourself. Be the horse, feel the weight, do thumbnail sketches.

Hehe, I have acted it out. Felt strange to do it though, but I did get a better idea of the animation.

horserearing_04 (
- Added more frames to 72
- Changed the animation of the rear legs in the beginning. Rather than taking a step back, they shuffle forward and then rear.
- Animated the tail.... it's pretty bad, might as well disregard it
- The file shows 3 animations. The only difference is the timing of the right rear leg stepping back.

I tried to break up the legs a bit by not having them do the same thing (going up and landing at the same time) I think I need to exaggerate it a bit more. And I think I made the rising too slow, need to speed it back up.

Thanks again everyone.

Hay (pun intended)! I have a couple of horses of my own and I get to watch them rear once in a blue moon. Your latest update is lookin' really good. I like the longer hangtime, and I also like the feeling of weight in the horse's torso and shoulders when he lands. One thing. When he rears up, he needs to have his body positioned more over his back hooves for the amount of time he stays up. In your video referance, the horse does more of a hop than a rear, and the chest shouldn't move very much. But with your animation I really like the beginning of the rear, I can almost see the muscles in his back pulling his chest up. Really good! just balance him out better!.
Good luck!:thumbsup:

- Reduced frames to 61
- Made the drop a bit harder
- Now with forward movement, the horse doesn't go back to its original location but still maintains original pose.
- Softer landing, the studio didn't want an angry stomp.
- Broke up the legs a bit more.
- Tail still sucks, it's being animated with an ik spline. I'm considering on animating it with fk.

Thanks Corey. I moved the body back and stiffened the chest some.

Now that I look at it, when it gets on its hind legs it doesn't look like there's weight being applied to the feet. I'll work on that next.

Wow, I've made some progress since the first one eh? :)
