I am fed up with ragdoll problem
It took me too much time to optimize ragdoll physic for my characters
Regardless how much effort, ragdoll still dance like hell

Is there any a real GUIDE for a smooth ragdoll ? or any note any suggestion to solve 'break dance' ragdoll

Why physic works so well but ragdoll.
Look at this...

If the case, make sure the ragdoll Collison proxies don't collide with each other, only the world this is what's probably causing the ragdoll spasms.

Btw disabling self collision for the ragdoll, will also have a nasty side effect that is the ragdoll parts will interpenetrate each other, so you need to make sure to put good movement limits in the ragdoll joints to prevent that.

Another idea is to add more damping or gradually increase it when the ragdoll started on either ragdoll or ragdoll's bone actor, so it will move slower, heavier and less likely to dance, also less likely to get launched when they piled up or walking on them.

I haven't look at the source code for it, but what is the effect of gravity on the ragdoll? What happens if you double the gravity?

RE: I am fed up with ragdoll problem
Hi,
Ragdoll creation is here:
https://github.com/Esenthel/EsenthelEngi...l.cpp#L137
Which uses joints here:
https://github.com/Esenthel/EsenthelEngi...t.cpp#L474
createBodyHinge
createBodySpherical
Later here and here:
https://github.com/Esenthel/EsenthelEngi...t.cpp#L195
https://github.com/Esenthel/EsenthelEngi...t.cpp#L238
You could experiment with modifying the source code.
I remember ragdoll worked more stable in older physx versions, maybe engine ragdoll/joint codes need to be tweaked for the newer version. But I'm too busy with other things at the moment to look into that now.

RE: I am fed up with ragdoll problem
I hope Esenthel don't mind me mentioning and posting links of other engines here but if someone reads this and think in UE4 or even Unity, ragdolls work flawlessly then you should read the following, this guy is making his game on UE4.
https://outofhell.net/2021/08/13/all-par...e-process/

And Unity3D 5
https://forum.unity.com/threads/how-can-...ut.328348/

Making ragdolls work well, is a surprisingly trick business no matter the engine.

Strange. UE4 Ragdoll works quite nicely for me.

RE: I am fed up with ragdoll problem
Cool effect wink
Default esenthel tutorial ragdoll has some shakiness / issues but not so big like yours. So you could try to investigate more, your own codes and ragdoll setup in the editor.
Sorry but at the current state of donations I can't improve/investigate ragdolls at the moment.
Now I'm focusing to finish my game - https://facebook.com/DungeonHeroRPG
The way to go would be probably google for some PhysX ragdoll tutorial source code, and try to replicate the code in the engine.
Sorry that I can't be more helpful about this right now.

RE: I am fed up with ragdoll problem
A simple workaround is just skip ragdoll and use some death animation. That will work good enough.

RE: I am fed up with ragdoll problem
Is there any plan in the near future to update physx to 4.x and add the missing physx module ?

Maybe an idea of when that would be implemented might help find the temporary solution

I can understand some of the frustration that has been coming off this thread regarding
the ragdoll. it is not in everyone coding toolbox to be able to pull that off

On the flip side, making B-boying are easy, looks cool, and of the chart!
Though I wonder what is your Ragdoll bone and AG_RAGDOLL collision group look like because I never experienced those yet, just a bit of bouncy.

I thought you're working on World of Esenthel. Wonder if my android save file is still around.

RE: I am fed up with ragdoll problem
I'm working on both remake of the dungeon game, and World of Esenthel.
Dungeon remake will be released in a couple months, and World of Esenthel later, because that's a much bigger project.
Remake will not support older savegame files wink Too much has changed.
