Jets Model Rigging Debrief #2: Expression Based Cat Ear Movement with #vbridger ! This isn't your run of the mill cat ears with wiggly physics and animation- this makes use of your expressions and moves the ear like an actual cat!! 1/X #Live2D #VTubeStudio

As a non-cat owner, I needed to know the basics on how the cat moves its ear based on expressions. After a quick google search, I have determined 2 expressions that gives a lot of life to the ears, namely angry and fear/sad(in which case I just named this sad) 2/X

In a quick Summary, what I did was: 1. create formulas for sad and angry in VBridger 2. add the same tracking parameters in live2D cubism 3. use the tracking parameters as inputs for the cat ear physics 4. link the VBridger parameters to the tracking parameters in VTS 3/X

How I tackled this is too long for twitter, so here's a scuffed google docs on how I did it! This rather advanced, and I am not confident that I explained it well. So I HIGHLY advice reading up on the fundamentals first before trying this out. 4/X

In retrospect, It's a nice quirky addition to Jet's model. It adds a lot more character to the ear as opposed to just a wiggly thing on the head. If I were to tackle this again, I might have added more jiggles. P.S. I'm pretty sure this can also be done with pure physics only.

IMPORTANT DETAIL I FORGOT!!!!! You need to download the nvidia tracking version of Vbridger to get the approx function working!!!!!

This is awesome! I'm trying to study and recreate this myself but I'm struggling to get the code to be valid, ((Brows)+(Mouthsmile)) is working, but the code fails when adding in the approx(A,B,Delta) function :( is there something I'm missing?

YOU MADE ME REALIZE IMPORTANT DETAIL I FORGOT!!!!! You need to download the nvidia tracking version of Vbridger to get the approx function working! this can be done easily in the game properties in steam. right click vbridger app in the library list > properties > betas.

ok this is actually pretty damn detailed Im loving this

Ham your brain 🤯 this is so cool and adds so much expressiveness to the model!!

this looks fucking amazing, definitely the best cat ears I've seen 🫡
