EYE ADVANCED - Realistic Eye Shader

can I import the eye model into blender without problems ?

 

Exchange the object in Unity... Simply delete the existing eye objects and put EyeAdvanced Eye Prefabs in their place, parenting them to the eye bones of your character model.

IF the eyes in your character are not separate objects then you'll need to first delete the eyes in a 3d modelling app, before bringing the character into Unity.

 

No, You should use EyeAdvanced Materials and Prefabs in Unity, not in a 3D modelling app.

 

this is how it looks for me: https://ibb.co/qFTKDg8

 

the character will be animated..

 

rigged & animated ^^

 

From your screenshot it looks like the eyes are separate objects. Simply scale EyeAdvanced prefabs to the same position/size and delete the original eye objects. If you rig the character, then parent the EyeAdvanced prefabs to the eye bones for eye animations to work. Should be all you need to do.

 

it will be rigged in blender . . . how does that work ?!

 

In Unity you go to the eye bone object in your character hierarchy and drag the EyeAdvanced prefab onto the bone object, which makes it a sub-object of that object (this is known as "parenting" the eye to the bone object). The EyeAdvanced prefab will then automatically follow the bone rotations.

 

okay i am beginning to understand it ^^ i hope

so if the original eyes are rigged & animated, I can still exchange them in Unity, and the animation would still work...

I hope I got that right :0

 

Pretty much. Unity objects will not automatically inherit animation/skinning data from a skinned mesh, BUT they WILL follow animated bones that they are parented too.

 

@Works-Dev you can use the shader and it's material on any eye model that has the same UV setup. But as chingwa mentioned, it is easier to use the included mesh and replace your model's eyes with that compared to reworking the UVs of it's original eyes. All of that can be done in Blender of course and it is not too difficult. Just make sure the eyes end up in the same place and are rigged to the same bone as the original eyes were. It isn't possible to just put the material on some random eye mesh, because how should the shader know, where the center of the eyes are, etc. that's not how modeling works..

 

I bought it yesterday & it looks really good

only I don't know if I can exchange it properly... i will experiment a little...

 

Yeah, good luck with that! Remember that experience with Blender is experience for life, since you will never be able to not afford that tool. ;-)

 

why doesn't it work that the eye delitions moves ?

I do not know what I'm doing wrong.

 

@w0rks-Dev Make sure the correct directional light is in the dilation slot. Also dilation does not work while not playing, try playing your scene and checking the dilation function.

 

Oh, I thought it would also work in edit mode xD

 

Thanks for this great asset!

I've switched my project to URP and now the sclera is getting dark areas when further away from the camera. This happens with and without LODs.

Here's the demo scene in builtin SRP with the camera further away, looking good:

And here's the demo scene in URP, with dark areas on the sclera:

How can this be fixed?

 

@Faikus I'm glad to hear your enjoying EyeAdvanced! These dark areas in URP seem to be related to texture import settings. What I recommend is to disable the "generate Mip Maps" setting on the Texture importer for both the eyeball_iris texture and the eyeball_mask texture. If you are still seeing this then you should reduce the "limbal ring amount" setting in your eyeadvanced material until you no longer see this artifact.

It's possible there is something in the shader that is not clamping texture values properly in URP. I will take a look into this. In the meantime I think the above should help a lot.

 

Thanks, disabling mipmaps worked!

 

Hi I have downloaded your demo project and got few questions.

First of when I set pupil dilation to 0% I got iris darkening on the border (only in a girl scene), this might be the same problem as above but it is an official demo so I had to ask.

I want to have white sclera but in this demo it is red when I set sclera color to white, is this changeable ?

Is it possible to have even bigger iris than what demo allows ?

I need vertical pupil changeable to big oval (cat like eyes) but I don't see any settings of that kind in demo.

 

@koirat Thanks for your interest in EyeAdvanced!

I think the eye darkening you're seeing in the demo is due to the limbal darkening setting (which not adjustable in the demo scene but certainly is on the material). I only see it when using large pupil sizes, so this could then be adjusted accordingly as needed.

You aren't able to get a completely white Sclera in the demo due to the underlying base texture having a reddish wrap around the sides and back (assumed it will be incorporated into a character so would not see most of it). You could replace the sclera texture with a white texture in order to get full white.

The iris max size is determined by clamping in the shader, so by default you would not be able to get bigger than what is shown in the demo.

It is possible to do cat-like pupil shapes, though it is not shown in the demo. you would simply need to replace the iris and iris mask textures on the eye material. There is an example cat iris/mask texture included.

 

I just started working with your asset and I'm very pleased with the results. I did have one issue where the eyes started looking black as they got further away from the camera. I discovered it was the Limbal Ring Amount causing the problem and setting it to 0 fixed it. Is this a bug by chance? I don't see any difference up close with any value so it seems like an unnecessary item. In the image, you can see two identical sets with the top set to 0 and the bottom set to 1.

 

@reggie_sgs Yes this seems to be a bug when using EyeAdvanced in URP (as detailed in the posts above, also see the above for a partial solution regarding clamp settings) Hopefully I'll have a URP shader update to fix this soon.

 

@chingwa , Hello, Can I easy to make a animation for iris in your eyes shader by change UV of iris texture?
I need to animation like rotate the eye iris. Can i do that with your asset?

 

I don’t recommend animating the UVs, as it might inadvertently change the expected mapping and cause graphics glitches. I instead recommend rotation the eye object, or better, parenting EyeAdvanced prefab to your eye bone, and rotating/animating the bone.

 

Hi, is it possible to change the color of the pupil? (I have a specific use-case)
Otherwise the shader looks incredibly realistic! Well done.
Greetings, Fabian

 

@MrBrightside There isn't an option in the material to change the pupil color. I will investigate adding this as a feature. However if you don't need the pupil color to be editable you can just change the pupil in the main texture to be a different color (the texture in the "iris texture" slot).

 

Thank you for the quick answer, I think changing the texture is sufficient for now, but adding it to the material would make it easier for me.

 

Hello All,

I'm happy to announce that Eye Advanced version 1.1.1 is now ready for download...
Download Here: http://www.tanukidigital.com/download

This update adds adds the limbal ring shader feature into HDRP and URP render pipelines, which was missing it before. It also improves limbal rendering by giving a new option to use a color tint to the limbal ring, and improved some of the rendering for more realistic look. Those who were already using this feature may need to adjust their settings slightly after upgrading. Finally the minimum compatible version has been raised to Unity 5.6.7, though I don't expect many are still using such an old Unity version at this point.

To enable SRP support make sure to import EyeAdvanced into your existing HDRP or URP project, then double-click on the relevant .unitypackage file from the newly added "_SRP" folder. This will import and update all shaders / textures / materials as necessary for that pipeline.

Version 1.1.1 will be available on the Asset Store later this week.

As always, let me know if you have problems/questions/feedback etc, either by email or on the forums!

All the best,
Justin Kellis

Sweet! I would love to see some screenshots, maybe a before and after of the update!

 

Hello, and thanks for the beautiful eyes! About VR compability, I made a build for Quest 2 and the eyes of my character were not visible. Is this shader not Quest compatible?

 

Hello, is HDRP 12 (Unity 2021.3) supported?

 

@ThisGuyThatsHere Yes, It is compatible with 2021.3 and HDRP 12.

 

Hi! Is this asset compatible with the latest versions of Unity (2022.x and URP 14)?
