IK Twist Doesn't Work in Maya 2020

[tkr.k]

As the title says, IK twist doesn't work in Maya2020.

I didn't do anything fancy at all. I just made an IK and tested out the IK twist.

This function is too fundamental not to test out before releasing Maya so I'm wondering whether it's just me or not.

Hello,   

Same for this one.  I'm not seeing any problem with Maya on my windows 10 machine.  Can you make a copy of your preferences folder (C:\Users\user_name\Documents\maya\2023) and then relaunch Maya with new prefs and see if the problem still occurs.

Take a look at the type of ik Solver you are using. 

 As you can see from the "inputs" in the channel box. 

Your 2020 example is using an SC solver or Single Chain solver. which does not have twist

while Your 2018 example is using an RP or Rotate Plane Solver, which has the twist functionality. 

When you create an ik Handle you can choose the type of solver to use. 

The default solver is set to SC    .. open the options and you can change it. 

You can also change the solver type in the attribute editor.

Thanks for your input.

It's on me. I set current solver as SC solver so it's an expected behavior.
