I have a master tier sub and have content sharing enabled in a campaign, a friend of mine has the EGTW and I can acces the book, but when I want to create a character, i.e. Echo Knight, it doesnt show. But he can use my content to create characters.

On the “home” tab of the character creator, the toggle next to “critical role content” needs to be on (red).

Yup, it's enabled but still doesn't work :(

You can only use the content shared to you specifically within that campaign. Are you attempting to build this character in that campaign?

That's it, thank you! :D
