Puppet2D integrates with Unity’s animation system and adds mesh deformation to create bendable joints for skeletal based animation.
Ranked in these QuestionsQuestion Ranking
Pro Mesh Deformation
Instead of having to change sprites to bend legs or other joints mesh deformation changes the mesh shape based on joint weights to bend and move.
Pro Inverse Kinematic bones
Bones will move and rotate reacting to the position of the rest of the skeleton. The animator does not have to animate each part of a joint but rather have it follow realistically. Also can be used for ragdoll effects based on physics.
Pro Built on top of Unity’s animation system
Mecanim and state machines work natively since Puppet2D builds on top of Unity’s built in animation system.
Con Forced editor scaling causes problems
Puppet2D adjust the scaling of bones in the editor for display purposes, which results in unintended behavior if other objects use a bone as a parent.
