Hello, has anyone gotten the new FEM sliding constraint to work? In a simple example it just behaves as fixed constraints between the two FEM objects. I can't get any sliding behavior. What's the secret? Thank you!

I've discovered that the FEM sliding constraint does not work with the stable neo-hookean variant. The correct behavior is only seen when using the Corotated Linear model. I believe that this is a bug as it is not advertised to only work with the specific corotated model. Using Houdini 18.5.351

Already logged it, just wanted to see if anyone else has seen this or had work-arounds?
