EYE ADVANCED - Realistic Eye Shader

Does Eye advanced work in Unity 2019?

Thanks!

 

Yes it should work in 2019.x without any problems, as long as you're using the standard Unity renderer.

 

Thank you for the fast reply.

Great! I will buy it then.

 

Hi,

I am having a little problem with the auto "pupil dilation" feature. I wonder if you can help me.
In the demo scene the "auto pupil dilation" works fine but when trying to use the feature on my own character, it doesn't work. You can see the attached picture to see my setup.

Any help would be appreciated!

Thanks!

 

@netpost Hmm, I'm not really sure why it wouldn't be working. It operates based on the Intensity setting of the directional light, and generally expects it to be 1.0 or higher. If you have a lower intensity you may see mixed results. Also it only runs in play mode. Perhaps try disconnecting the scene eye object from the prefab (i.e. gameobject/break prefab instance) and see if it helps?

 

Thanks for the quick reply.

I deactivated my character leaving the eyes all by themselves and it worked. I then reactivate my character game object and it still work, but it is more subtle because the lighting is not as strong as when there is no head wrapping the eyes socket. So I understand now that the intensity of the light make the dilation happen and not necessarily the direction of the light.

So everything is good. Thank you for the great support!

 

It seems like the web player version doesn't work. Any suggestions? Thanks!

 

@starsmiling Thanks for letting me know. I'll have to take a look at the website code to see what the trouble is. In the meantime you can download a direct demo appliction (for PC) here:

Edit: I got the page working again but the webplayer isn't working. You can download the PC demo direct from the page now: http://www.tanukidigital.com/eyeadvanced/demo/

 

Can you provide any hints on doing this. Or support if I get stuck?

 

@FS9606 If you can replace the eyes on your character with a normal Unity sphere, then you can setup Eye Advanced eye prefabs in the exact same manner. Generally this involves positioning the eye prefab in Unity and parenting it to your character "eye" bone object. Easy as pie.

 

Hi this looks great, can I ask a few pre-sales questions

1) Does it work with HDRP?

2) My animated characters are alembic files from Maya, can I just simply apply your eye material to my characters eye geometry?

Many thanks

 

@dmattock EyeAdvanced will not currently work with HDRP. There is still so much in flux with Unity's pipeline that it hasn't been worth investing the time (not to mention frustrations whn they change from version to version). Once they have an official release that is not marked "preview" I will investigate putting out an HDRP-compatible version.

As for using the material by itself, in some cases this may be possible (depending on the existing geometry / uv coordinates), but in most cases you'll need to replace the existing eye geometry with EyeAdvanced prefab objects... parenting them to any existing eye "bone" transforms to control movement.

 

Hi checking back again on whether you have tested in mobile... The results look different than in editor for iOS on iPhone XS Max

@ina interesting. Are you sure it's not just a difference in lighting overall? The skin also looks different as if the scene light is either warmer or with a higher intensity, or possibly it's a difference in postprocessing between editor/device?

 

turned out to be a LOD issue! different diffuse texture for each LOD...

 

Any change of a LWRP/ URP version soonish? Would be really appreciated

 

@timbokoppers I'll be investigating LWRP /URP and possibly HDRP versions in the next couple months I think. Exact timing is still TBD.

 

@chingwa LWRP should be high on your priorities. Anyone doing modern VR dev can't use this product until then

 

Hi, I'm trying to implement daz characters into unity, they use combined meshes for both eyes and the textures look like this:



Is it possible to use your shader to render these eye models?

 

@Harekelas Hmmm... you would either need to have separate eye objects and replace them with EyeAdvanced prefabs (which is the recommended method), or rework the eye UVs so that they follow the EyeAdvanced uv set. Below is an image of the UV layout:

 

Can I simply change the texture to fit the UV of the models?

 

You could probably do that. I have not tried it myself but I can't think of why it wouldn't work. The main problem with doing it this way is that there are multiple textures in Eye Advanced that combine to build the eye visuals. Eye Sclera, Iris, normal, and mask textures would all need to be edited.

 

Yeah, I plan to edit all of them.

 

Tried to edit the textures, but it doesn't seem to work, I've readjusted the UV of the eyes, see if this can work.

 

I remodeled the eyes into a sphere like this:


And the uv is unwrapped like you suggested:


But now I got this kind of artifact in the middle of the eye:


The material looks correct, I think it still got something to do with the uv or the mesh. What do you think the cause might be?

 

I'm not really sure what would be causing the center spot. Possibly has to do with calculations in the shader for parallax or the pupil dilation or iris size as all 3 of these do calculations based on the center of the uv layout. Or it's possible it's something in the mesh. If you'd like to send a copy of your new mesh over I'd be happy to check it out on my end. Feel free to email a download link to konnichiwa[at]tanukidigital.com if you don't want to post publicly.

 

I've sent you a dropbox link to my modified eye mesh.

 

This is the most beautiful eye effect on the asset store! When will it support URP? We very much hope it supports URP. Update please~~~~~

 

I have a question about this shader? Is it possible to bake the shader into a separate iris texture with Unity?

 

I'm not sure what you mean by baking the shader. Can you elaborate?

 

What I mean is How can I fix the eye iris texture and make it into a new texture with the shader?

 

Do you want to use this eye shader in your final product, or if you want to bake the eye effect into a texture then use another shader in the final product with the baked texture?
If latter, there is no way to "bake" the eye effects, you'll need this shader for them to look like this.
If you want a texture of the full eye (not as procedural as in this shader) with this shader's look you may need to create a new shader to generate this texture.

If you want to create and use your own eye iris textures for the eye, you can simply create your own texture through eyes' photos in photoshop then replace the iris texture with your own's.

And if your character model's eyes does not fit this shader's uv, you should change the eye mesh in blender or other 3d software and map the uv to this shader's texture.

 

I want to bake the eye effect into a texture. How do I do that in Photoshop?

 

You can't do it in PS, but you can write a shader to gather pixel color info from each uv coord. But why do you want to bake the results into a texture? A single texture won't have the parallax effects and the eye bulge effects in this shader. Why not directly use this shader and feed it custom textures to make them look like what you want?
I just don't see the reason here.

 

@Harekelas is correct. The shader is there specifically to render the special eye refraction and parallax effects. This cannot be imported into photoshop.

 

So what should I do?

 

I don't understand what you are trying to do. What is the reason that you aren't using the included eye prefabs (model/shader/texture) as intended?

 

Hello All,

I'm happy to announce that Eye Advanced version 1.1.0 is now ready for download...

Download Here: http://www.tanukidigital.com/download

This update adds support for both the HDRP and URP render pipelines. This was a much requested feature, and has been a long time in coming. I hope it helps to make your SRP transitions a bit easier. 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.

In addition to adding SRP support,here was a small fix for the overall brightness setting behavior, and I removed the old Unity 4.0 shaders from the package since they are over 5 years old and outdated by today's Unity standards.

Version 1.1.0 is also now available on the Asset Store.

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

All the best,
Justin Kellis
Tanuki Digital


------------------------------------------
RELEASE NOTES - Version 1.1.0
------------------------------------------
- Added HDRP Support (see _SRP folder for details).
- Added URP Support (see _SRP folder for details).
- Fixed Overall Brightness setting so that it now applies properly to albedo again.
- Removed Unity 4.x version of shaders from package

 

hello @chingwa
I tried importing Eye Advanced into a 2020.1 beta project with HDRP 8.1 and the overall Brightness seems to be off in that version of SRP. The shader is drawing and everything, but the eye stays almost completely black, no matter how much I increase the light intensity. Have you got any suggestions, what one can do about that?
Greetings!

 

@ElevenGame Thanks for the report! Unity beta releases always seem to have weird stuff going on, which is why I don't typically pay attention to bugs until the official release is out. But I'll take a look at 2020.1 on my end and see if I get a similar issue.

 

@ElevenGame I can only recreate this issue in the Demo scene that comes with EyeAdvanced. It seems related to the 2 demo "controller" scripts that are on the scene camera. With those disabled the light and brightness then works as expected. Also when I try the eye in a different beta HDRP scene the brightness also works as expected. Is this what you are seeing on your end?

 

@chingwa thanks for investigating. Disabling the controller scripts did not help in my case. But i found out that adding correct volume overrides to the scene with visual environment and sky fixes the issue for me. (I don't know why the hdrp default settings did not achieve that..) So the eyes are looking good now even in 2020.1 beta.

 

Great, glad to hear it’s working now!

 

Hey, was considering picking Eye Advanced up and was wondering if there was anything included for tear line rendering or if that's an exercise left for the buyer?

 

Hey @GuitarBro thanks for your interest! Considering that tear lines are usually very dependent on the face model being used (and the overall eye opening shape), this is necessarily left up to the end user.

 

Ok, thanks. Makes sense, just wanted to know what all I would be getting beforehand.

 

hello, i'm thinking about buying this Asset here ^^

I have the following situation: I have a realistic character and I want to give them beautiful eyes with this asset here, because the original texture / material doesn't look as good as I would like.

now my question: are there no problems with the UVs of the eyes ? If I apply this Material from the Asset to the original eyes, aren't there problems with UVs then ?

 

@w0rks-Dev It is recommended to not just apply the material, but to use the included eye prefab object as well... replacing your character eyes. In some cases it may be possible to use the material as-is, but it expects a particular mapping for the eye object, and you'll likely find even a small mismatch in the eye-object UVs will cause the EyeAdvanced material to not display correctly.

You can see a few posts up about a successful remapping of existing eye coordinates:
https://forum.unity.com/threads/eye-advanced-realistic-eye-shader.299760/page-4#post-5334102

But again, in most cases it's recommended to just replace the existing eye objects completely.

 

yes, but then I can't do anything with it . . i am not at all familiar with UVs and i'm not the modeler either...

 

when i buy it,. . can I then exchange the model in blender ?
