simple rigging setups using kinefx

 

typical basic kinefx rigging for organicish shapes

simple rigid body FK rig. Key points are packing each rigid part, and using the capture packed geo node. make sure the skeleton points are at the desired pivot points.

basic setup here - line as a skeleton, isolate the FBIK controller points. the MATCH BY ATTRIBUTE setting is usually what makes things work! Also on the FBIK node, you might need to tweak the tolerance parameter.

look at constraint but only in the X or Y etc

 

There's a Look At Constraint, in the Constraints tab, however if you only want this aim to work on the X, or maybe just the Y, you have to dig into the constraint, then go to the Common Tab (see top screenshot) and then only specify the rx or ry in the scope.

Remember to use Nulls to set custom pivots etc, then parent your desired geometry to the null.
