Hi all,

Just wondering if there's a way to limit a joint in Kinefx so it can only be moved or rotated a specific amount by a rig pose node?

Thanks,
Pete

It's not working with the Configure Joints node. Only god knows why.
You can use right-click Motion-FX/limit on the rig pose node. Not ideal, but it works.

Cheers

Hey, that works

I get a little worried about using chops, I've had some problems in the past with it updating a little wonky. That was ages ago though so maybe it's better these days. I'll give it a try,

Thanks!

Rig Pose Viewer state has Enforce Transform Limits option defaulting to False
so while in the state, press F to turn them on and it should respect the limits configured using Configure Joints SOP

That's really cool! It's just a shame you have to manually turn it on each time, I'd like the limits to always be in place.
It always reverts back to false too :/ That seems like a weird choice.
