As you've probably heard Antics' latest version, V5, has just been released and it looks like the team have hit a home run!
There's some info on the website, which among other features describes how
you can add expressions!
They say you use the emotion tool and then click on one of our predefined expressions to instantly add emotion and then you can use fine-grained controls to edit facial expressions intuitively, adding or taking away degrees of happiness, sadness, anger, and so on. To really hone in on the exact expression you need, and convey a truly subtle emotion.
I totally agree. The smile on my face gets bigger every time I think about those sliders!
Full review coming soon.
