This is a 3Dmodel and animations of European robin.
Two models were included.
These models tailored to Blender's unit.
The wing span is about 22cm.
The feature of the model is that it has a realistic proportion of the skeleton so that the pose folding feathers and the flapping animation are reproduced.
The flapping motion is not just a vertical motion but a three-dimensional motion of the humerus, ulna and metacarpals is reproduced.
The animation set has basic items that you can move freely within the game engine.
note:To use Root Motion with UE4, I need 3dsMax.
Animation names are listed in the documentation.
