I'm just starting to learn KineFX and trying use the Attach Joint Geo node to create rig controllers. After creating them I am unable to select them. In a Rig Pose node when I mouse over the joints, the controllers become highlighted, and rotating the joints themselves also rotates the rig geo, so I know they're connected. I just can't select the controllers themselves. Is there a trick to setting them up properly? Is it a bug?

can you share your hip?

NURBS may be the cause. POLYGON might work.

Did You expose the rigpose parameters to a digital asset interface?
And did You modify the default state of Your rig asset to "kinefx__rigpose" int the digital asset properties?
