Continue improving Final IK, it's documentation and add more features. I will be concentrating mostly on developing the Full Body IK and VR IK part of the package, based on Your feedback and practical use cases.

Anything else I should know before buying?

Make sure to read the Online User Manual about the components that interest you the most.

There is a section about the requirements and limitations of each component.

Looking forward to working together,

Partel Lang - developer of Final IK
