Fresh install, latest version, new character.
Can’t export OBJ, FBX.
(Only iAvatar, iClone send, USD, BVH and GoZ are availbale)
Now what? 
Hi…
Does it remain greyed out with all characters, including standard CC3+ characters, or is this issue with one particular character?
You should also try deselecting the character and then reselecting it to see if it resolve the issue…
Hi Pete!
I’ve found the problem. I had to update the texture pack, now it allows to export all.
Thanks!
