Can I use animations from Blender's rigify, into Unity3d?

I read up on the unity forum about Rigify being bad or not totally useful.

I don’t know if I’m asking this right. But I’m wanting to export my animation for my character, into unity by using rigify.

I believe I would have to export my skeletal that moves with my animation.
Then I simply make it a child of my Character Model.

If there’s something I’m missing, please let me know.
I’m kind of new to 3d animations.

Hi, yes you can use Rigify. In short you need to rig your model and then animate the skeleton then export your model and animations - check the Unity documentation and tutorials:

Good luck and have fun!
