IKControl for Custom Rig not Working

I’m working on a spider rig that I’d like to animate procedurally with Inverse Kinematics. However, I’m still new to Inverse Kinematics and rigging in Roblox. As you can see in the video, the model is rigged correctly (I think?) but the legs won’t move with the part despite having an IKControl. Any advice?

It’s best to move the IKControl that is inside the “RootPart” and move it to the Humanoid

Hey,did you find a solution? sorry for bumping but ive been struggling with the same problem,and i have no idea how to fix it, can you give me information on how you rigged it and how did you get it working?
