I ran a quick test over the week to see if the Creature Animation Tool would work with PlayCanvas.
Looks like a really interesting tool animating. And works without any issues into PlayCanvas, I just dropped in their FBX export sample and setup the materials. Animation worked with no alterations.
Thank you for posting this. I was just looking for a good sprite design tool and this looks great!
