Rigging birds is always a challenge, especially when the film has a low budget and we cannot afford hair simulation with feather collision. As a result, on Butterfly Tale, we have to be very creative! With Singing Frog Studio, we used feathers in geometry with a system described below. Take a look! 🎬
✅ All wing feathers are combined in only one mesh (left and right side together), excluding the ‘’finger’’ feathers.
✅ The arm feathers are deformed by a skinned lattice, which allows for smooth silhouettes and easy deformation.
✅ To prevent the feathers from stretching in width due to the lattices, post-envelope blendshapes are added. These correct each feather’s width based on angle interpolators that are specifically placed on each wing articulation. Having a single mesh for the arm feathers also allows for easy modeling and mirroring of the blendshapes.
We were very happy with the result in this production context!
