What do you call a CGI version of an actor?

Question

For example, in the movie Star Wars Carrie Fisher played Princess Leia, but because she was not as young as she used to be, they used a CGI version of her. What do you call the CGI version of an actor? Is there a particular word for it?

Here's an example sentence:

Disney used a ___ of Carrie Fisher in 10 other Star Wars movies.

Answer 1

CGI can be used as a noun adjunct like this:

Disney used a CGI Carrie Fisher in 10 other Star Wars movies.

It's short, specific, and it's something people definitely say. Here are some examples:

• VLOG: LucasFilm Confirmed No CGI Carrie Fisher

• On top of all the action, special effects, explosions, brief clips of fight scenes, and of course, a CGI Samuel L. Jackson who looks way better than actual young Samuel L. Jackson, this trailer does one very important thing… give the audience a better idea of what Captain Marvel will be about. —New Captain Marvel Trailer… Oh Yes It’s Good

• Watch new ‘Pirates of the Caribbean 5’ trailer, featuring CGI Johnny Depp as young Jack Sparrow

Answer 2

The phrase that you use in your question is correct and clear

Disney used a CGI version of ...

You could also use "virtual"

A virtual Carrie Fisher

But this is less explicit and perhaps less clear.
