What version of the AnyBody Modeling System and the AMMR are you using.
I cant replicate the error. Do you have anything else affecting this node?
What example model did you start from?
The version of AMS I use is 6.1,and the version of AMMR I use is 1.6.6.Maybe the reason for this problem is that these two versions are too old.
I started with the StandingModel in Demo. I only added the definition of this node, so I don't think I have anything else to affect this node.
If you can't help because the version is too old, it doesn't matter. I will try to solve this problem myself. Thank you in advance.
There might have been a change to one of the leg models in the time from your version to the current.
We generally don't support such old versions.
Try to see if the sRel of the node is somehow affected by another object.
also see if the Foot segments are somehow different between the two leg models.
