Automatic Eye Blinking Animation in Under 5 Minutes (Unity)

[@Shihiko]

Nice, the short and clear formats always easy to follow along.

[@ReForgeMode]

Glad you're here! I am planning to be uploading more frequent and more impactful tutorials this year, so stay tuned!

[@gamelevelarts4831]

Nice tutorial, easy to set up my character. thank you!

[@ReForgeMode]

Haha, glad I could help!

[@MrRiceKrispyNotTaken]

hey dude I'm curious if you're going to make a tutorial for creating ragdolls that uses the VROID Component, you're rocking with these tutorials that are God sent 🔥🔥🔥🔥

[@ReForgeMode]

Haha, glad I could help! Ragdoll huh? Sure! I add it to my list of things to make. That should be quite fun!

[@MrRiceKrispyNotTaken]

Also, I'm curious if you're going to make a tutorial of using the newer UniVRM since there's a lot of stuffs that were added but i can't figure how to use them 👀

[@ReForgeMode]

Oh yes I will. It should only take a while to make, since I am working on a different project these days. The newer UniVRM is way different than the last.

[@MrRiceKrispyNotTaken]

@@ReForgeMode looking forward to this, since the current documentation of it is... lack cluster even if you translated it lol

[@Mikes-Code]

Did someone deal with black flickering particles on the model mesh when animated?

[@ReForgeMode]

Huh, that seems like a shader error. Please send your image to our discord server forum so I can analyze it.

[@nagiaVR]

thank you so much for this!!!!

[@KikoDevOfficial]

hello will you make tutorial on the player script of vriod model??

[@ReForgeMode]

I did. It's right here: kzbin.info/www/bejne/jobYpqp4icuAd68

[@KikoDevOfficial]

@@ReForgeMode no like no jumping just crouching and sprinting waiking

[@ReForgeMode]

@@KikoDevOfficial You can just disable jumping on your character controller. It is more effective to use existing character controller.

[@valsinoen9114]

Hello! If I use a walking animation, will it not be interrupted by an eye blink animation?

[@ReForgeMode]

Hi! No, it shouldn't. If you use the script method, you can instead put the eye blink on LateUpdate() instead of Update() to override the animation. If you use Animator, make sure to put the Eye Blink Layer on the lowest layer. The lowest layer got priority over the top ones. Cheers! 😄😄

[@ammoniti0n]

This doesn't work for me. There are no errors for the script. And for the animation, the eye doesn't blink even though in the Animator, the Blinking is being used. I think the problem lies in the controller slider unable to be changed when in play mode. This goes for some others. Is there a fix on this?

[@ReForgeMode]

Have you disabled the VRMInstance component in your player character?

[@ammoniti0n]

@@ReForgeMode Oh, I missed it. Thanks a lot!

[@aucusticguitar8069]

@@ReForgeMode I disabled VRMInstance and I still cannot modify the Blendshapes in the playmode. I even unchecked clamp blendshape weight range in the Player settings to see if it would change and it still doesn't work

[@katsukiz2002]

Hi thanks for your tutorial!! I could attach it, but it doesn't blink during play mode. I changed the name of blendshape of the script. Di you know how to solve it?

[@ReForgeMode]

Well, the name of your eye blink blendshape must match with the one in the script. If you need further help, please join our Discord server so you can send the screenshot of your scripts. Link is in the description.

[@rizydev9501]

I have one question, the characters above are very beautiful, but for the characters in Vroid Studio, in the sample models section, you don't need to put credits, do you?

[@ReForgeMode]

No, you don't need to. The characters I'm using is a sample VRoid model from the application itself. If you create a model from scratch, those are completely yours. The only time you need credits and permission is if you use other people's models.

[@xLeroVA]

do u use an old version of unity because i cant follow exactly even tho its still there but somewhere/ renamed other in the newe Versions

[@ReForgeMode]

What is "still there"? Be more specific.

[@oppaidah]

Is there a way to make the character always looking at the camera/viewer?

[@ReForgeMode]

That is possible in the old UniVRM. But the new version is a bit more complicated. You can somewhat do it right now by enabling that component at the start. Just put the camera into the field in there.

I have a error: Array index (1) is out of bounds (size=1) UnityEngine.StackTraceUtility:ExtractStackTrace ()

[@ReForgeMode]

That means there is a slight error on your for or while loops. Make sure to check if the length or index are copied perfectly from the video. You can also download the project files from GitHub. Link is in the video description.

@@ReForgeMode I was tried to turn off this script and this is working without script :D Why I need this script so? It is working just with animations

[@ReForgeMode]

If you notice in the video, I presented two ways to do blinking animations: using a script or using animation. You can pick either one. The advantage of using script is that it's flexible. You can adjust how often your character blinks at any time and can even stop your character from blinking by just disabling the component. Using animation, you can't just change just the speed of eye closing without affecting the entire animation. The advantage of animation is that it's simple. You just put it there and it works.

[@NullZ1]

I did the same , the solution was on the Private void awake dont use "Fcl_Eye_close" name , use the name that you gave your blendshapes. , if you use the Fcl_Eye_Close , Unity will try to find that name and give you an error thus giving you a "-1" since its a non existant shapekey .

[@nekomanz]

but how to make it so your hand gesturs that close your eyes not override your blink so your eye lashes go into your face

[@ReForgeMode]

What are you asking here? Hand gesture or eye lashes problem? Most problems could be solved with Animator layering. Put the layers you want to prioritize at the very bottom. So, Facial expression should be at the last layer.

[@nekomanz]

​@@ReForgeMode I need a tutorial on animator layering honestly. Also idk im trying to find any videos on how to use them im trying to do the layer thing its hoestly dump you cant keyfram animators off

[@ReForgeMode]

@@nekomanz I am still not sure what problem are you struggling with in the animator. But here's the basics: When layering different animations together, you can set an Animation Mask in each layer to focus on just a certain part of the body to apply the layer to. For example, if we just want head movement, we can create a Mask to just the head. Then, you can also create an Empty State where no animation was assigned in the layers. This will make the Base Layer animation run normally.

[@nekomanz]

@@ReForgeMode nvm i did it lol

[@ReForgeMode]

@@nekomanz Haha. Nice! 😄😄

[@aucusticguitar8069]

By any chance do you know how to add subtle hair physics without enabling VRM Instance?

[@ReForgeMode]

Hmmm... Not at the moment. I am looking to fix VRMInstance if possible. Somehow, something breaks its code there. Maybe I'll be able to disable just one of its modules.

[@aucusticguitar8069]

@ReForgeMode its okay i figured it out. I used a dynamic bone script to set the physics on each section of the hair

[@liro.u]

​Hi @@ReForgeMode ! Do you have found a way to implement blinking and let VRMInstance Enable ?

[@liro.u]

Ok i have find a solution, if i set the update type to null it work fine (the hair animation and the blink animation)

[@liro.u]

here is a better code to implement the blinker with the VRMInstance enable and the updateType set to update or late update using System.Collections; using UnityEngine; using UniVRM10; namespace MovementSystem { public class EyeBlinker : MonoBehaviour { protected Vrm10Instance vrmInstance; protected ExpressionKey blinkExpressionKey; [Header("Properties")] public float blinkInterval = 5.0f; public float blinkEyeCloseDuration = 0.06f; public float blinkOpeningSeconds = 0.03f; public float blinkClosingSeconds = 0.1f; protected Coroutine blinkCoroutine; private void Awake() { vrmInstance = GetComponent(); blinkExpressionKey = ExpressionKey.Blink; } private IEnumerator BlinkRoutine() { while (true) { yield return new WaitForSeconds(blinkInterval); float value = 0f; float closeSpeed = 1.0f / blinkClosingSeconds; while (value < 1) { value += Time.deltaTime * closeSpeed; vrmInstance.Runtime.Expression.SetWeight(blinkExpressionKey, value); yield return null; } vrmInstance.Runtime.Expression.SetWeight(blinkExpressionKey, 1); yield return new WaitForSeconds(blinkEyeCloseDuration); value = 1f; float openSpeed = 1.0f / blinkOpeningSeconds; while (value > 0) { value -= Time.deltaTime * openSpeed; vrmInstance.Runtime.Expression.SetWeight(blinkExpressionKey, value); yield return null; } vrmInstance.Runtime.Expression.SetWeight(blinkExpressionKey, 0); } } private void OnEnable() { blinkCoroutine = StartCoroutine(BlinkRoutine()); } private void OnDisable() { if (blinkCoroutine != null) { StopCoroutine(blinkCoroutine); blinkCoroutine = null; } } } }

[@apreako]

hello sepertinya tidak mengaktifkan skrip VRMInstance bisa menyebabkan error, walaupun animasi bisa berjalan dengan baik, tetapi saya menemukan referensi pada dokumentasi UniVRM terbaru dengan menginstal juga package VRM_Samples-0.112.0_6a46.unitypackage, disitu saya masih menemukan Skrip Blinker dengan nama VRM10Blinker. setelah saya tambahkan ke model saya skrip tersebut berjalan dengan baik tanpa harus menonaktifkan skrip VRMInstance. Pada model default juga sekarang sudah terdapat opsi untuk mengatur LookAt VRM versi 1 Unity 2022.3.1f saya sudah test dan berjalan dengan baik dengan menggunakan cara tersebut

[@ReForgeMode]

Hmm, oke terima kasih infonya. Error seperti apa ya? Terakhir saya cek, VRMInstance itu bikin masalah juga klo mau bikin Facial Expression lewat animation, klo misalnya mau bikin transisi antar Facial Animation.

[@apreako]

@@ReForgeMode ya betul sekali, saya juga sedang kesulitan membuat expression melalui animation, akhirnya saya mencoba implementasi melalui script seperti pada script VRMAutoExpression yang merupakan script bawaan pada package VRMSample. Versi terbaru memang baru update beberapa hari yang lalu, sampai sekarang saya masih kebingungan bagaimana caranya fungsi LookAt pada VRMInstance bisa menggerakan seluruh kepala bukan hanya bola matanya saja. Hmmm

[@apreako]

BTW saya sangat senang mengunjungi channel anda, semoga channel ini terus berkembang, karena untuk kedepanya saya yakin penggunaan VRM pada unity akan semakin berkembang, sukses terus untuk channel ini
