Live2D eye physics for 3D VTubers - Pendulum Chains

[@clumsymoe]

Suvi on the mission to merge the best of two worlds 💪! I love this new series, it's very creative!

[@tundrakitty]

Wow, this is definitely a step up from the eye highlight jiggle! Thank you so much for the continuous updates and tutorials. I hope you know how much it means to those of us who wish to be anime catgirls but can only afford to DIY models lol.

[@CakeZBread]

I'm going to have to try this out. I have only done eye physics on live 2d models but finally our 3d models can have eye physics thanks to you✨

[@Kana_Fuyuko]

Thanks for the tutorial and update Suvi!!! VNyan is the future!!!

[@HollyriousYT]

Thank you for this! I used it and now have wiggly eyes YAY

[@NishiyamaAika]

Finally it's about damn time Tv T i was searching all over the place for this!

[@moritzruffonei3960]

it took me a while, but finally i was able to make this work today

[@Chrypsis]

suvi the absolute goat of 3D tubers

[@mikantine]

Great tutorial!! Although I am having problems with the highlights and eye keyshapes in unity since I cannot find them even with Hana-tool(i have all the other keyshapes though). How do i get them? :3

[@mickipou]

Waitt omg your voice is smooth and cute like a cat's purr

[@Namipew]

This is very cool, will probably try it out! Thank you Suvi!❤

[@KitsuneShan]

Why are you so genius and kind?

[@xcigaro1637]

This is so creative! Well done Suvi!

[@LumieValkea]

Suvi, you're a hero!

[@briarbaye]

I'm not sure on how exactly I should make the blendshapes for the eye and highlights. Do you need to go about it in Blender?

[@Suvidriel]

If you have vroid model you can use the hana tool data in description. However, if you want to create your own or have non vroid-model then Blender is a way to do it yes.

[@briarbaye]

@@Suvidriel Okay, thank you Suvi!

[@clarissa_g]

Hi! I'm trying to implement this and I'm a bit lost on how to add the additional blend shapes for the eyes to the model using the example data. Do I add the contents of the text file to the PerfectSync_Vroid_v1_0_0_Female.txt file?

[@clarissa_g]

Nevermind, I managed to figure it out. This is great, thank you!

[@MKPanda0428]

Hello! Can you explain how you figured it out? I'm having trouble. Thanks!

[@clarissa_g]

@@MKPanda0428 it's been a while so I don't have the full steps, but I think I was not using the hana tool correctly. I think I had to manually add the blendshapes in Unity via the editor

[@melandeity]

I had this working with a different version of my vtuber but the eyes stopped wobbling since I updated an outfit. I have the parameters, blendshapes and everything, but they still dont move. Any ideas as to why?

[@Cathekk]

I love you Suvi 😭😭💖

[@I3etoCuevas]

Hello Suvi, I cant download the example data is there somewhere else to download it? Thank you so much for all the hardwork ur doing ❤❤❤

[@Suvidriel]

It should be there but do note that it's using http and not https. My operator overcharges for ssl-certificate installation so I don't have one there yet~ Sorry about that. You may have to use some other browser than chrome if that's the one blocking it.

[@I3etoCuevas]

@@Suvidriel I tried with Ms Edge Canary and it worked, Thanks Suvi

[@sehens]

Excellent work as always, Suvi! You have been providing us such nice tutorials for soo long, thank you! One question, are you planning on making a video about how we can do that cat mouth that you have on your avatar (and maybe rig it too)? I have been looking for tutorials about it for so long but theres none 🥲 I'd love to see one from you!

[@Suvidriel]

I just did in blender. I think I saw a cat mouth come with the perfect sync shapekey data for Hana Tool as well when I was testing the other day.

[@LavAriz]

The cat mouth is already a shape key in the stable Vroid app

[@dailydriver3882]

So relaxing o.o Is difficult for me to stay awake

[@gabriellecomeau2338]

You are very skilled ! super Kawaii ! best avatar i 'v seen !

[@SakuraSeed8]

i use ip facetracking on my model using hanna tool. when i go into blender i cant find any of the blenshapes that you used. ie the eyerighttall

[@Suvidriel]

they need to be added. There's the hana tool data in desc that you could use but alternatively you can do them in blender

[@SakuraSeed8]

That is very important👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍

[@Killakuma]

I'd love to know how to make arm rotations with blendshapes!!

[@Suvidriel]

I was testing this on stream last Tuesday actually but yea it might be worthwhile to do a tutorial about it.

[@YOKERMEISTER]

Nice tutorial! I would love to have this but my avatar doesn't blink, can I enable auto blink in Vnyan like VSF?

[@Suvidriel]

You could implement a node graph for the autoblink. Create a timer loop to turn on the blink blendshapes and then open after a while. This is how I've done it few times on stream

[@YOKERMEISTER]

@@Suvidriel oh thank you! I will try ^^

[@YOKERMEISTER]

@@Suvidriel I tried but I couldn't realize how to do it, when you are on stream is too late here in my country. Anyways, thank you for your hard work, you always helped me a lot with your tutorials :D

[@aieu_.n]

This is so awesome! But I have a problem. The eyes shapekey (those one in 2:25) of my model had worked just fine in Blender, but when I import into Unity, all the eyes blendshape didn't work 😭when I have the blendshape on and off, nothing change on my model at all

[@Suvidriel]

Did you set the blendshape clips as well? When you add a shapekey in blender it doesn't get turned into blendshape automatically - they also need to be added to blendshape proxy as blendshape clips.

[@aieu_.n]

@@Suvidriel ohh thank you so much!!

[@GamingHamster86]

Is the Hana Data still up? I was not able to find it.

[@Suvidriel]

It's still up but it the website doesn't have ssl so I guess chrome etc might not like it. I moved the file to dropbox and updated the url in comments so it should download correctly now

[@Zmienny]

:O AWESOME!

[@Louberries]

The example data unfortunately seems to not be working on models exported from VRoid version 1.27 and up 😔 I believe they changed things about the face mesh, so now the shape keys will just implode the eye instead. HANA_tool needed an updated BlendShapeData too for 1.27 for that reason.

[@Suvidriel]

Yea it won't work due to them changing the vertex indexes. You'll have to make those in blender instead

[@literallynobody7477]

How do you setup the blendshapes like that?

[@Suvidriel]

You can do them in blender or if you have vroid model you can use the hana tool data included in the description

[@literallynobody7477]

@@Suvidriel yess i use the hana tool and unity but i dont have those I believe 😭

[@redchick11]

How do you make the shape keys for the highlight and eye jiggle?

[@Suvidriel]

Basically you need to make 2 opposing shape keys. In my case I tend to do like a wide eye and then thin eye to counter that and another pair of tall and short eye. Those are done in Blender

[@8l00my]

You're so cool!!!!

[@ladycapri689]

the blender does not take me u.u in the vnyan I think there is something that I do not do well

[@GooseyGoblin]

LETS GOOOOOOO

[@水の呼吸-t9j]

3Dモデルでーじじょーとー(とても良い) 素敵

[@Katubug]

How do you decide which bone to attach the outputs to?

[@Suvidriel]

You need to make a node graph that sets output parameter value to bone rotation. Look into Hebi's arm sway graph in the discord for ideas on how to do that

[@MrMerlinWasTaken]

is it just me or is this not working with the newer vroid versions past 1.27?

[@Suvidriel]

It does still work - I'm using it personally on my streams as well
