It can be quite challenging to get back from a ragdoll state. In this tutorial it is shown step by step how to go into ragdoll and how to get back to the locomotion state. It is based on the Third Person Template and uses three animations from the Meta Human Sample project. We go from preparing the physics asset over going into ragdoll and how to use the pose snapshot to blend from the last physical driven pose into a linear animation. It touches how to adjust the tick, how to get proper rotation and what settings are needed in the state machine so Animation Blueprint and Character Blueprint can work in the right order.

Perfect timing. I appreciated the new features/settings covered in this tutorial. I’ll give it a try early next week. Thank you.
@AndiEpic Hi dev this is great, I love that you showed all the issues including the settings, order of nodes as I had problems with this prior, and you provided solutions. This is much appreciated. I was wondering if you could do tutorials on blending it with death animations so that we can still have certain random animations but it will eventually be diffused randomly with the physics thereafter.
This is a video I made with physical animations, ragdoll ang getup previously, some logic I used from a getup asset. Thank you
I am using this fetal pose in the video even if it is not “really” used. With the motors you can try to drive the physcis a bit more towards the pose. I assume you can do something similar with a death animation. It is also a bit easier when you do not need to recover from it.
That’s a really cool video, thanks for sharing. I have to check out this tutorial next
Had to add ragdoll recovery to my game and came across your tutorial. I already had ragdoll set up and I’m using a different skeleton but it was easy enough to follow along and modify my setup. Not only do I have this really nice recovery now but all the other details you mention really improves the quality of the ragdoll and I’m super happy with the result. Thank you so much
hi,
thanks a lot for this great tutorial
you brought it clear to the point and it´s a joy to learn from it. after searching for this effect i finally got it in game and thanks for the metahuman animation tip, works like a charm. the only weird thing was, i first took the new skeleton from u5 and retarget it to u4, but this messes up the animation. then i tried using u4 skeleton straight and it works without any problems
many thanks!
cheers
Omg, adding that capsule body to the root of the skeleton was the key to fixing months of frustration of trying to get this to work smoothly. Thanks so much
(still using UE4 btw)
Great Tutorial Everything works great, I also had the small camera glitch But when I Implemented the ( vector spring interp ) It was even worse, I have gone over that part many times but I cant see the issue.
so I had to implement this solution instead.
How to make a character automatically rise after falling and coming to a complete stop, based on this tutorial?
Thank you, Andreas! Works like a charm
Another solution for the camera glitch. The issue is when setting the offset, it was set relative to the object root (which is on the ground), while the camera tracks middle of the capsule. This causes camera to jump half-capsule height, if the character is in the air (on the ground it is mitigated by the capsule not allowed to go under ground). If you get pelvis to capsule offset instead, the camera shouldn’t move at all. Better to do it every time the ToRagdoll is called, because pelvis offset can be different in various animation phases. Now because capsule center follows pelvis (instead of capsule bottom followinf pelvis in the original solution), capsule bottom tends to go underground. So changing the trace to go from tracked location half-capsule down instead will detect when the capsule bottom goes underground and snap it back. And that’s all. There is still small glitch when Ragdoll finishes (seems the physical capsule position is not the same as the tracked one, but I didn’t figure out that yet). Here are the blueprints:
-
At ToRagdoll start (the rest is the same, BeginPlay code removed):
-
Completely reworked capsule tracking (without Vinterp):
In the capsule tracking, I track from pelvis, not from the pelvis+offset, because that location can end under ground. Not sure if it can cause issues with different character.
I just started learning Unreal, so the things can be a bit rough. In any case, thanks for the tutorial, I learned quite a bit, including a few nice tricks.
Adding animations to downloadables would have been nice. 4gb unexpected download is not so nice.
