Hi! Getting a little frustrated here, hoping for a solid explaination or best practice.
EDITED 4.25.2020*****    https://youtu.be/05d01pBx74A     **********
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^example youtube video
I have been animating with iClone since about 2015 to create animation loops for 2D fighting games. 
This issue I am about to explain has come and gone and I don't understand why some updates I have this issues and then other updates the problem is gone. 

Current Version: iClone 7.72.3818.1 

PROCESS:
I import my custom character that uses the iClone standard animation rig ( iAvatar or CC3 Character Creator file directly exported to iC7)
I select the character and press 'N' to dial up 'Edit Motion Layer'.
I left click the LOCK icons adjacent to the feet (ankles?) 
After turning the LOCKs on, I click on the 'hip bone' and I either do a soft rotation (press E) or move hip position on z,x,y axis (press 'W')
Using the options listed above I make very soft movement adjustments to hip rotation and hip's Z position to create an animation loop (Think standing Idle stance)

PROBLEM:
The feet on the animation loop slide around instead of staying stationary. 
This has come and gone with different updates in iClone 6 or 7 and I would love to know why and how I can end this problem. My process hasn't changed but something has in the appliaction

Thanks!!! :)
Ps: Perfect world, it would be great if we could dial into the actual x,y,z, coordinates via the UI and just copy the position of said bone and apply it to desired frames.
If I am an idiot and have missed a glaring option, please, call me out!
:D

Hi

The feet are locked as default if you click them you will unlock them.
You can get the x y z bone co-ordinates in the edit motion layer by selecting the FK Mode and selecting one of the bones.

Thanks Chris - I don't think you understood exactly what is happening.

Even with the lock enabled the problem is persistent - the application slides the feet around in the filler between key frames, I will upload it on video to demo.

When you first open the Edit Motion Layer panel, the feet are locked by default. Notice the T and R indicators in the dots, and also that the little locks for the feet are closed. So if clicked them thinking you were locking them, you were actually unlocking them. See here:

When this issue becomes overly annoying and well over the level I can tolerate, I use Reach Effectors to animate feet.
Animate all bones normally, but if you need to move/rotate feet, animate those reach effector balls.
Inconvenient and annoying - yes, but gets the job done.

Thanks for the link!

Someone posted the solution and then deleted the comment - or atleast, I can't see it on the thread anymore - anyway - issue resolved:
Thank you!

Did you ever figure out how to fix the sliding feet issue? I’m having the same issue but I’m not sure how reach effectors would help.
By 4u2ges - 5 Years Ago
When you enable Reach Effectors you animate feet with Reach Effector Dummies as oppose to feet bones.
As I mentioned, it is not exactly convenient, but does fight feet slide effectively.

For this example I animated pose to pose.
If I need to lock the feet for certain number of frames between 2 poses, it is almost impossible to do with feet/leg bones
(otherwise you have to do dozens of tweaks in between frames cluttering your timeline).

You could also go back to iclone 2: :hehe:

Now, RL doesn't care anymore.

I don't remember it working in iClone 2...:unsure: A button is easily added...:P

Hi.

Is this the motion ruler tool you have in the background of the video?

I see there is more people having sliding feet issues.

We discussed the example karate kid pose problem from RL manual I try to replicate to learn.

https://forum.reallusion.com/440330/Walker-UVI-Footstep-Foley-Designer-ExperiencesHints-Tips?PageIndex=6

So, should I also try to use the reach effectors as well in my problem?

Have you finished making the motion ruler tool?

Thanks for all the help:-)

reach effectors and foot contact helped in my test case.
