Hi Sebastien! I'm also just starting with APEX, but it appears to me that for your "ik1" and "ik2" autorig nodes, on the "Driven" tab, needs to have "_l" in each of the root, mid, and tip parameters.
So it becomes:
ik1: "hip_l", "knee_l", "ankle_l"
ik2: "scapula_l", "elbow_l", "palm_l"

Remember to set unique names for the polevector and ikhandle in the "Controls" tab so front and back legs have individual controls

Now you might see one of the annoying issues I've run into with IK. It doesn't seem to like mirrored skeletons with negative scaled transforms. It might be worth it to add new drivers to your driven tips maybe with the transformdrivers Autorig Component.

I'm still new to all this, so plenty of grains of salt. But I hope it helps you.

Hi Sebastian, i couldn't get the multik autorig component so i just used the smoothik on both the arm and legs instead.
The issue James mentioned also happened, you have to set the skeletonmirror node from scale to rotation.

Hi guys,
The apex setup is better, but I have a lot to fix before I can use it. If you have any advice, I would be really thankful.

Hi, please have a look at some of the example files to see how they are set up.

Hi William,
What is your suggestion for eyes with the different parts? I use the jointcaptureproximity for the eyesball, but for the rest should I use blendshape or skining?

I found that video on sidefx website:

Thank you for helping.

Hi have a look on youtube for rigging tutorials, the DCC doesnt matter. The principles are mostly the same.
Then try and build it in apex.

The chicken and the luchador are both set up using pose blends for the facial animation, you can have a look at how that was set up.
I am using a custom setup for the pose blends in those examples. We have a brand new pose blend component that you can use for that.

Thank you William for your feedback, I always know 3ds max and Maya rig, I will check out the new pose blend
