Face scale on Football demo

[andrewdeutsch]

Hey Jeeliz,
I've been using the Football Fan effect as a foundation for a project (it's very very good) and would love to be able to add some elements to the chin. When the mouth is opening, though, the texture image doesn't scale. Can you recommend the most efficient way of making the y scale of the 'mask' respond to the mouth movement?
Thanks so much!

Hi Andrew,

In the function callbackTrack, executed for each frame, the argument is detectState.
You can get the opening of the mouth with detectState.expressions[0] (expressions is an array because maybe in the futur we will add other expressions). This is a coefficient between 0 (mouth closed) and 1 (mouth open).

However, to amplify the movement, you should apply a smoothstep function to this value for example : var correctedSmoothStep(0.3, 0.6, detectState.expressions[0]).

Currently the makeup is applied on a transparent face mesh, rendered above the face.
I think the best way to scale the mask with mouth mouvement would be to have 2 face meshes, one with mouth closed (like the current one) and the other with the mouth opened and to mix them using the mouth opening coefficient as keyframe coefficients.

Thanks, Xavier, that makes sense. I didn't see the blend file for the mesh in the project demo assets. Ideally I'd start with that for the open mouth mesh. For many other projects you have blend assets available. Am I missing it's location?
Thanks.

This is true this is an error we would add it by tomorrow (the developer who had done this demo is in France)

thanks!

Hi Andrew,

The football_makeup demo is pushed in the threejs jeelizFaceFilter demos. You'll find the .blend file for the face mesh here.

I'm currently updating the other available demos with the missing Blender assets.

Amazing, thank you Benjamin.
