Your instructions are unclear because you write
If you are on iClone 8.6 or Character Creator 4.6 → just apply the AI Render patch in Disk1 (ignore the iC / CC patch in the ZIP).
But when you install the ai render button doesn’t appear at all in iclone.
Is there any solution to this or can someone who has installed IC version 8.6 simply not use AI Render?
