Planetary Gear vertex anim in UE5.4 We used the pivot painter's pivots not only for the anim but also for computing the tangents for the anisotropic effect.
The animation is created using "Easy Vertex Anim plugin" which we are developing. It's a plugin that allows to author vertex animations in the Unreal Editor and a large library of vertex animation effects. It makes easy for anyone to create a vertex animation directly in UE5.
