Shape Animation Tool 2.0
At least I updated this tool. Main feature is layers. Now deformation can act independently and with different keys. Overview of the tool you can see in videos from previous version. Also I place the good sample of the using another tool with similar method, as I think, in Hotel Transilvania after 1:35. You can buy this tool from this site for 20$. Free version 1.2 is available also in creative crush.
