No IK foot on Metahumans?

I was expecting to get this out of the box but it doesn’t seem to be the case

Hey @KEV6172!

It is! :star_struck:

Here’s a tutorial on enabling foot IK on the UE mannequin:

(The first half of the tutorial)

And here’s a tutorial on replacing the UE mannequin with a metahuman:

Hope this helps! :innocent:

I’m not using any mannequin, I created a BP from scratch with the metahuman output, IK doesn’t work.

You’ll need to do it the way I explained above to be able to use the already prepared foot IK.

Only Metahumans shipped with City Crowds come with IK bones. The method proposed by Vis Agilis requires you to use the “live retargeting” method. Alternatively, you can add virtual bones to the Metahuman skeleton to have the same functionality of an IK bone. Therefore, the Control Rig “Foot Ik” will work correctly.

It doesn’t work, when I assign the control rig as in that video the character enters in an A Pose

The boolean checked after added the control rig node doesn’t exist either.

Well, it works as it can be seen from the tutorial. You’ll need to provide us some screenshots showing the steps you took if you need help troubleshooting.

To be clear, here’s what you need to do step by step:

  • Migrate one of the UE Mannequins including their dependencies. You can create a new project with the Third Person Template, and all of the dependencies will be selected when you right click on the SKM, then Asset Actions > Migrate. (If you like you can exclude unnecessary stuff such as textures tho. But make sure to include the Skeleton, SKM, and the rigs) After that, all you need to do is to hit OK and select the Content browser of your existing project.

  • Create a new Animation Blueprint for the mannequin (or use the existing one if you migrated that too) and plug the Control Rig node into the main Out Pose of the Anim Graph. The tutorial also shows how to add that Should Do IK Trace pin.

  • Now that we have a character that has IK feet, we can move onto replacing the SKM with a metahuman. Follow the tutorial to see how to add a metahuman to your project, and copying the Skeletal Meshes into our existing Character Blueprint. Then you just set the leader pose, hide the original SKM, set the bones to always refresh (again, you can see how in the tutorial) and that’s it! Now you have a metahuman with IK feet :blush:

Hey something just came to my mind. Perhaps you didn’t select the CR asset from the Control Rig node :thinking:

I suspect that might be the case since you also mentioned A pose. Like I said, I’d recommend first following the both tutorials carefully, and then sharing the steps you took in detail with us if you encounter any issues.

I barely know what I’m doing but got it working by creating the virtual bones, copy/paste everything from the 3rd person char rig into the MH one, and replacing then bones names.
