Viseme RIG test

Hello,

in order to faster the mouth animation process of a character,
i try to create a viseme rig.

I have put on an object a pose morph tag with 6 sliders for 6 visemes.
I created a dynamic text in user data, to edit viseme orders .
I created an Xpresso tag, with python node, to control visemes sliders.
It works, but in a boolean way !

I want to improve this Xpresso and python Rig to control sliders
in a linear way (from 0% to 100%, or 100% to 0%) !
With duration for the moving sliders between viseme orders
With conditions for the position of the sliders (e.g.: if slider 1 at position 0, go to 100, if slider 2 at position 100, go to 0 ....).

How can i do it ?
I'm a python rookie !

Thank's

Hi Gal, thanks for writing us.

With regard to the issue reported, it looks to me like some sorting of unwanted data-clamping effect due to type casting. To be more helpful please provide your code snippet ( or a complete test asset) in order to dig further.

Best, Riccardo

Hi Ricardo,

Thank you for your answer.

I've a little bit improved my xpresso nodes, simple but efficient !

The viseme are controlled in a boolean way = step key frame.
With controlling the global intensity of the pose morph tag,
i can have more interpolation of the lips movement between the viseme step keys frames.

How to improved python code in order to have viseme linear key frames ?

Thanks
Best regards

This is my simple python code :

Hi Gal, thanks for following-up.

With regard to your setup, without changing too much things, you could simply consider to add an additional float parameter to your VISEME data - in order to have three input params "neutral", "VISEME" and a "weight" - and use its value defined by a curve in your python script (below to keep your naming scheme is called Input2) in order to change the weight of your VISEME rig.

def main():

    global Output1, Output2, Output3, Output4,  Output5,  Output6,  Output7,  Output8,  Output9,  Output10,  Output11

Hello

Thank you Ricardo for the code and this option.
It works for me !

Is there a way to control an interpolation of data (e.g. 0 to 100) on a duration (e.g. 10 frames) with python, with only one order keyframe ?

If you have an advice or a weblink to better learn python for C4D, i'll take it !

Thanks

Gal

Hi! You could go for CTracks via Python. You'd have to get the track for a position parameter, for example, or create one, then get curve, then add keys. Later, you could simply range map it back to your Xpresso rig. it It's definitely doable!
