Rig Your First Humanoid in Maya Pt.12 – IK/FK Arm Switching

Welcome to Part 12 of the Vertmode Beginner Humanoid Rigging Series! In this episode, we complete the Junk Buddy arm rig by building a functional IK/FK switching system for the arms inside Autodesk Maya. With both the FK and IK arm systems now complete, it’s time to blend them together into a seamless animator-friendly workflow. This is one of the most important systems in a professional character rig and allows animators to switch between: ✔ FK controls for arcs and natural movement ✔ IK controls for contact, posing, and precise positioning We’ll walk through the full setup process while discussing how professional rigs manage visibility, constraints, and animator usability. ━━━━━━━━━━━━━━━ IN THIS EPISODE ━━━━━━━━━━━━━━━ ✔ Creating an IK/FK switch attribute ✔ Blending between IK and FK arm systems ✔ Managing control visibility ✔ Using constraints for seamless switching ✔ Preventing double transforms ✔ Organizing clean hierarchy systems ✔ Building animator-friendly workflows ✔ Testing the rig for animation usability ✔ Troubleshooting common IK/FK issues We also discuss: ✔ Why animators constantly switch between IK and FK ✔ IK vs FK strengths and weaknesses ✔ Common beginner switching mistakes ✔ Keeping rigs modular and scalable ✔ Building production-friendly rig systems ✔ Why clean organization matters for complex rigs By the end of this episode, the Junk Buddy rig will have fully functional IK/FK arm switching, bringing the rig much closer to a complete production-ready humanoid setup. ━━━━━━━━━━━━━━━ DOWNLOADS & RESOURCES ━━━━━━━━━━━━━━━ Download the Junk Buddy Model: https://vertmode.gumroad.com/l/abrgkb...
