cheap face mocap pt1

I’ve recently watched this tutorial on Pluralsight (ex digital tutors) on Creating Custom Facial Motion Capture in Maya

It’s a nice and simple tutorial that teaches you to track some facial motion capture in matchmover, export the tracked data as locators in maya, and then parent the locators on an existing rig.

The only bit where it was a bit “meh”, is the part where you have to constraint the generated locators to the animation controls.

Generally, face control have values that range from -1 to 1 and from 0 to 1, but the controls I’ve exported from matchmover had crazy values, and to fit the animation curves within these ranges can be a very boring job.

Therefore I thought…wouldn’t be awesome if I could select the locator and re-normalize the curves based on a range I decide?  So I made a script for that!

Now it doesn’t have a UI, but that’s the next step. If you want to play with it now, just copy and have fun with it!

 

In the meantime I’ll leave you with the mocap video I made 😀


I should really build a facecam because trying to stay still while performing was very hard…

More updates soon!

Motionbuilder constraint tool update

hey I’ve updated the parent script I made on this previous post.
Now is more efficient, and it will change the name in the navigator based on the type of constraint (I’ve set it to work only on position, rotation and parent but it’s easy to modify it)  so it will look like this:

hope it helps 🙂

Motionbuilder aux effector switch

Hey everyone,
I’ve recently wrote this script (which I suggest to bind to an hotkey shortcut) that switches the values of the aux effector between 100% and 0% and will disable the “animatable” attrubute.

enjoy!

 

 

Woot! I finally finished Codeacademy’s python course!

It took me ages to complete this course, but I can finally remove it from my to do list of this year! 🙂
I’ve learned loads, and I strongly recommend to bot anyone who wants to learn this language from scratch and to those who want to improve their fundamentals.
This course is really well explained and if you get stuck you can always turn on the hints or read people’s questions in the q&a forum.

Below you can find the entire course structure:


Python Syntax

This tutorial will introduce you to Python, a general-purpose, object-oriented interpreted language you can use for countless standalone projects or scripting applications.

Tip Calculator

Now that you’ve completed the lesson on Python syntax, let’s see if you can put your newfound skills to use. In this project, you’ll create a simple calculator that determines the price of a meal after tax and tip.

Motionbuilder parent constraint tool

I’m currently working on the ultimate parent constraint tool for Motionbuilder.
So far the tool is very simple: select the child, select the parent and you have your constraint. In the future I want to add the option to automatically key the weight values before and after a certain range and choose the type of constraint as well.

This is what it looks like in action:

And this is the code:
