Motion Path Pro

Motion Path Pro is a Blender addon available on Superhive (formerly Blender Market).

It is designed to make the work of polishing animation faster and easier.

Key features include:

• Editable motion path: edit motion paths right in the 3d View.
• Real-Time Motion Path Updates: It allows users to update motion paths in real-time, from both the graph editor and viewport windows.
• Object and Rig Compatibility: Motion Path Pro works with any kind of object, including meshes, cameras, and empties. Its Paths List feature uses a calculation method different from Blender's original motion path and works with any rig, no matter how complex or heavy it is. It is confirmed to work with rigs like Rigify, Auto-Rig Pro, and custom rigs.
• Animation Tools: It offers several advanced controls, including Reference line, Timeline visualization, Handle setup, and Full keyframes control.
• Drawing Functionality: The add-on includes features like "Draw Animation in viewport window" and "Draw poses". When drawing animation, users can choose the transformation axis they want to draw on and control time and space. This drawing functionality works with both objects and bones.
• Smart Offset: A new feature available is the Smart Offset operator, which is an animation tool designed to offset all the keyframes on the selected fcurve.
