For more direct control, use Inverse Kinematics (IK) to drive the entire tentacle chain with a single target controller. 2D Workflow (After Effects)
Use an Array Modifier with an "object offset" (using an empty) to create a tapering effect where the tail gets thinner toward the end. PB HD - Tentacles for anime girl.mp4
Convert pins into "bones" using the Duik Angela or Duik Basel plugins. Use FK (Forward Kinematics) for rotation animation, which creates natural deflection. For more direct control, use Inverse Kinematics (IK)
Use procedural motor systems to automate the "wavy" idle animation of long tentacle chains. 3. Anime-Specific Animation Techniques For more direct control
