Thanks a lot for helping me and especially for the explanation !

I do not know all the Houdini's subtleties to make rigs and I wanted to make it with only bones (without Nulls) to export it on Unity but I guess I have to go step by step when I build the rig not to have so many issues . ^^"

Thanks again .

Hello,

I have a strange issue while animating with IK, sometimes when simply moving the model, the IK snap and jump irregularly. And bones does some unwanted rotation when slightly moving them.

I've attached a file where you can see the issue described above.
just open the file, click on play… the animation is broken on the legs.

Thanks for your help

I create a FK/IK switch system for the arms of my rig ( I know ,it's quite basical). To controle it , I create a parameter (Integer) which controle the Blend of the IK (the value of the parameter = the value of the Blend). It works but when I create an animation of the FK/IK's controller ( a switch from FK to IK ) , the IKs are broken ( it's like if the IKS are no more applied to the bones ). The only way that I found to ‘'fix’' it was to switch the IK Dampening from 0 to 1 to 0 but it did not solve completly the problem ( it comes back after some manipulations ).

I share the files who contains the problems ( with a simple animation of the FK/IK's Switch).

Thanks in advance to anyone who takes the time to read this and maybe help me.
