AnimExport Pro is a Blender addon that provides a production-tested pipeline for moving animations from Blender into Unity or Unreal Engine. Root motion extraction, clip splitting, Mixamo cleanup, humanoid validation, and batch FBX export all run from a single sidebar panel in the 3D Viewport.
Root motion extraction pulls root bone translation into object-level animation, with a choice of horizontal, vertical, or both, and can inject motion back into the bone hierarchy for in-place animation. Clip splitting lets you define named clips with start and end frame ranges in a scrollable list, then split one long action into individual clip actions offset to frame 0 that preserve interpolation, easing, and handles. A non-destructive blend preview uses temporary NLA strips, and Mixamo cleanup renames bones from a built-in map, strips the mixamorig prefix, and applies a scale fix.
The addon supports Blender 3.0 and newer, tested through the 4.x series, and exports FBX to Unity and Unreal Engine 4 and 5. It works with custom rigs, Mixamo, Rigify, or game-engine skeletons on Windows, macOS, and Linux.
