Hi,
I recently bought CC4 and have been wondering what is the workflow like to source custom animations without having to buy iClone. 
My target software is Unreal Engine 5.

I have three questions

1. If I buy for example this pack
https://www.reallusion.com/ContentStore/iClone/pack/iClone7-Motion-Rifle-Combat-Patrol/default.html
Will I be able to import and preview that in CC4 and export to Unreal Engine 5 or will I still be required to buy also iClone?

2. Also, I see good looking animations in Actorcore website. But will I be able to use them with my CC4 based characters?

3, Will I be able to anyhow animate CC4 characters in Maya preferably by using Human IK control rig? I tried but the workflow gets so complicated that I might be faster off by starting from scratch and skill CC4 altogether.
