FK problems

[Rough1]

Hello,
I have bought a model that is already rigged with a FK setup. I want to bring him from standing to a sitting position, but because of the rigging, its very hard to keyframe the extremities. The big problem is, the feet are going through the floor, and keyframing is not looking good. How can I keep the feet stuck to the floor?
Thx in advance,
Simon

Hi Simon,

Planting the foot flat on the ground might take a few iterations. Since I don't have the file here, I can't tell you more.

Typically, Inverse kinematics is used to make the end of a leg more easily placed.

Please have a look here:

Around minute 20, see timestamps. Typically a 2D IK setup.

Let me know how it goes.

All the best
