Reallusion’s Cartoon Animator 5 desktop cartoon production software is coming soon, and there are offers in the emails such as ‘buy an upgrade and get version 5 free when it appears’. It’s good software for making that kind of animation, especially for a small studio. Professional, fairly easy to use, very well documented and supported. Though you to be aware that you probably need to budget four times the initial ‘sticker price’, if you’re going to fully get into the expensive Reallusion ecosystem with motion add-ons and expansion packs and suchlike.
