IK/FK switch generated from apex limb component: question 2026年8月20日5:14

AntonMoss
Here's another solution that I think works pretty well. I initially thought about going through the apex graphs to set up some bidirectional control, but then realized very quickly that you can run into some "conditional" issues, and the menu items, abstract controls, ik/fk, are pretty complicated under the hood. Then I remembered you can trigger selections by selecting a object, similar to what you see in the autorig component for the hand/fingers. What you're seeing here is a tool that allows you to specify a trigger, and when that trigger is pressed, it will then select any number of specified controls, in this case, the configs for the arms and legs.

Make sure you drop the am_TriggerSelection.1.0.bgeo component into your ../Documents/houdiniXX/apexcomponent directory.

Thank you so much for this. This is honestly a perfect way to approach the global IK/FK switching issue, and it solves the problem much more cleanly than what I was trying before. I really appreciate you taking the time to put this component together and explain it.

If you used the autorig builder, this might be an easier option for you in the meantime. Select the Main_Manager>Select All Configs, then set the ikfkblend to 0 or 1.

Thank you so much. I will take a look at this workflow. Cheers.

IK/FK switch generated from apex limb component: question 2026年8月19日11:50

Anyone know how I can add a button to the rig after the limb component that switches all the limbs for the arms and legs between IK/FK at one time?

Currently you have to change each manually. I would like a global IK/FK switch while still maintaining the ability to switch each limb if possible.
