Physical Animation Issues

[fallow depot]

Hey guys I'm following the tutorial here: https://www.youtube.com/watch?v=46NfgXlnCzM
I'm currently at 39:40 when he's showing the animation while the simulation is active, i've watched from 35:00 to 45:00 several times now but i can't for the life of my get my animation to react in the same way as the video.
Simulation simply just ragdolls as if it had no strengths; i can see the animation trying to work (Twitching in the legs etc.) but it looks nothing like the one in the video.
Any insight as to why this is happening and a possible solution to get it working would be greatly appreciated 🙂

Hey hey! Are you using Unreal 5? You might need to up the strengths of the values - the move to Chaos Physics has left phys anims in a very poor state haha

Heyo, Yeh i'm on the latest UE5 release, it's extremely bizarre, i have to set the strength etc. on every bone instead of just the spine as was done in the video
But then even with the strengths it doesn't show correctly in the preview of it, it just ragdolls as if nothing happened, however if you go in game and fire it, it works somewhat correctly.

However you have to apply it to every bone instead of just the spine, so the legs are also affected and don't apply the animation the same as in the video either.
This is my first time diving into physics assets so it's all new and i may just be being stupid 😂
