thickness of the open books

Hello Frank,

We have this in plans for version 5. So far the only option you have is to use the Scale gizmo.

I'll merge this idea with the main one of the same topic. Please feel free to upvote it.

Cheers!

was this ever added to version 5? I don't see it.

Not yet, there will be an update dedicated to books. We plan to do it there.

Exactly what I was looking for! It would be a great improvement. 

Boxshot 5.2 is going to be mostly about books and this was the first thing we did there. Unfortunately, it was hard to stop, so we went a little bit further, but hope you will like the results: https://boxshot.com/2020/04/21/boxshot-5-2.html

Boxshot 5.2.2 has all the books customisable, including the open ones. You can try it here: https://boxshot.com/2020/06/22/boxshot-5-2-2.html
