Maxscript: Biped Constraint

This is a maxscript (written for 3ds Max 2016) that I use to rig humanoid rigs, such as those created by Character Creator 3, to a 3ds max biped for animation purposes.

This is a work in progress script, this being version 3.  Eventually, I'll be uploading more detailed documentation, but for now, I'm releasing the script here.  Feel free to comment or start a discussion if you are having issues with it.  Feedback is appreciated and will be taken into consideration for future updates.

Tutorials

There will now be tutorials provided here.  

Tutorial 1: Rig Setup

Tutorial 2: Version 4.0 Documentation

Change Log

Version 4.0.2

• Addressed an issue where some rigs would still have incorrect rotation  after applying the orientation constraints.

Version 4.0.1

• New version available.  This version allows for rigs that do not have the same number of spine, fingers, etc., as those required in version 3 without needing to create more or unnecessary bones
• More features will be coming soon for this version such has tails and props

Version 3.3.2

• Small bug fix addressing one of the helper objects not being created.

Version 3.3.1

• Updated how hands are aligned for more accuracy.

Version 3.3.0

• Updated the population wizard to be more clear and include nub selection
• Updated the helper system.  Helpers can be deleted so they only some can be used instead of forcing all of them
• Rearranged some buttons and removed the Rotation Setup button.
• Included a tutorial link for version 3.3.0

Version 3.2.2

• When using the bone wizard, pressing right-click will enter the children of the selected object without progressing what biped bone you are trying to define.

Version 3.2.1

• Added a header that indicates which version the user is using
• Due to the increased interest in the animation recording tool, I removed a try-catch statement so users can get more details error information if the tool fails. 
• Note:  This tool was build with 3ds Max 2016, so using it in different versions may yield different results.
• Additional Note:  Animation recording was made with short animations in mind; animations over 100 frames, especially when recording every frame, can take some time.

Version 3.2.0

• Fixed a bug where recording the entire animation did not work.
• Added the functionality to  adjust which frames are used when recording (every frame, every others, every third, etc.)

Version 3.1.0

• More warning messages as opposed to just locking out them window when making a mistake
• When doing the final constraint, the root uses a Link Constraint instead of being a child of the temp rig, thus preserving the originally hierarchy better
