EYE ADVANCED - Realistic Eye Shader

I should’ve been more careful.

 

@Escope12 No Worries!

 

I bought the Eye Advanced Shader

 

I was recently viewing a presentation by Activsion/Blizzard on their research into realistic eye shading, and this part caught my eye in particular (ouch pun).

I think it would be fantastic if this could be supported.

being able to mask the reflection like this would up the realism. I know you have the shadow masks, but that's not quite the same thing, it darkens but doesn't really affect the reflection portion.

 

@CeeBee This should be doable. I could at the very least apply the shadow mask to reflections as well. Good idea, I will put this on my list for the next update.

 

Nice find! It's very subtle but compared to these off and on images, it shows how much more realistic it actually makes it.

 

Yes, chingwa will be happy to know that just about every other trick for eyes that they demonstrate in their presentation, his shader already has. (with the exception of the moisture mesh, but that isn't really covered by the eye shader.)

 

I would like to do something about moisture mesh, but it's kind of out of my hands since that has to be very specific to the character model.

 

Maybe a sample? And then a few pointers about how to customize?

 

Yeah I fudged something for the time being with a free "Puddle" shader I found on the Asset Store:





But, I can't say I'm happy with the result. Will probably circle back to that later. But it's ok for now.

Your eye however, looks great. Kudos!

 

Hi, I also wanted to report what appears to be a bug with the Sclera Size and the Sclera Shading.
I was seeing some odd effects and finally figured it out. I turned the shading up high to make it more obvious:


As you increase the Sclera Size, the Sclera Shading also scales along with the Sclera texture. You can only use the shading basically with a Sclera Size of 0.85 which is kind of limiting. Ideally, the Sclera Shading shouldn't scale with the Sclera Texture at all, it should stay the same scale regardless of the Sclera Size.

 

@CeeBee Thanks for the bug report! I will check it out this week and hopefully put together a shader fix.

 

@ceebeee I have a patch-fix available for the sclera shading issue you noted above. It also has a preliminary edit to remove reflections from the underedge of the eye, I added a new slider where you can control the reflection mask amount. Currently it is using the sclera mask texture, but I may add a new specific texture to control this before I release the next udpate.

Send me a PM or an email at konnichiwa@tanukidigital.com and I'll send you the patch.

 

I tried the patch, It looks good. It resolves the Sclera scaling issue, and I think using the Sclera and Iris shadow masks as the reflection mask is a reasonable strategy. Thanks for your work on this

 

Hello, I want to know that there is support for Unity2017.4.2f2 and deferred rendering and VR (Multi Pass) ^^"?

 

Unity 2017.4 == Unity 2017.3. Since it works for me, I can confirm it works for Unity 2017.4.

 

@Maskvp I support all Unity versions after 5.3.4, so 2017 is inlcuded, and official release versions of 2018 are included. Deferred rendering is supported as well. VR Multi Pass is untested... perhaps a VR customercan chime in here and give their input?

 

I'm on the fence with the asset because Unity Web player doesn't work with firefox (or at least for the majority of us it doesnt.) Can you upload a quick video to the thread here maybe, or provide a windows player? I just wanna see it in action a bit. Thanks so much, this looks AWESOME! -proceeds to scan forums for any missed examples.-

 

@Wolfride Hey thanks for your interest! You can download and check out a windows versions here:
http://www.tanukidigital.com/eyeadvanced/demo/demofiles/EyeAdvancedDemo.zip

 

Yeeesss thank you so much!! I can't wait to check this out; it's so exciting. And glancing through the thread, I saw someone mention extracting from demos (pertains to window builds, I would guess.) That is why I'd be okay with just video demos; if there is a risk for a piracy influx by providing more accessible demos, another solution should be presented.

Edit: Wow. This blows everything else in the Unity store away! Best eyes available to date. And I can actually afford this one on an indie budget. (At 40 I probably wouldn't until the end of the game, coming back to replace all the placeholder textures. Weird what a 5 dollar difference makes.)

I'm going to pick this up on next payday. Edit 2: Lawl caved and bought it now. Please keep working on this. Do what no one else is doing.

 

@Wolfride Thank you very much for your in depth review! I'm glad to hear you are enjoying the eyes Also I will take your suggestions into consideration for future updates.

Just FYI, you CAN add a glow to the eyes by changing the "Glow Color" setting. Just make sure to adjust the color alpha channel as well. This will put a glow on the entire iris... perhaps in the future I can make it more detailed where you edit a texture channel for this.

 

@chingwa @Stormy102

thanks for the reply ^^

 

I definitely love this assets from the photos and Demo but I can't use it yet, I'm already using the High Definition Render Pipeline so this asset is at the moment useless for me, I will definitely look at this plugin and wait for support

 

In general, don't expect a lot of support from plugins for HDRP in 2018. That's because from what I've read Unity doesn't expect HDRP to be completed or stable till the final release of the year.

 

Hi guys, does this asset work with emission? e.g: Eyes showing in the dark or emit light on eyeglasses.

 

@anomas yes, the Pupil has the option for an emission glow color in the shader. It is black by default, but changing the color and raising the alpha channel will allow the pupil area to glow.

 

I have purchased your EyeAdvanced and I totally love it.
Will you provide a version for HDRP, or do you think it should stay as it is?
I don't know if the new shaders bring anything good for us in respect to EyeAdvanced.

 

I was thinking that using the HDRP shaders might be a good decision (once it's out of beta) because then nothing can get broken anymore with new Unity versions, right?
I guess that you could utilize Lit shader.
Can you please correct me if I'm wrong about any assumption?

 

@OfficialHermie I don't have near-term plans to support HDRP. Just like many others I am waiting to see how the development of HDRP goes, and for Unity to release more stable and feature complete version. Eventually once the new SRP features are standardized I'll most certainly be doing some kind of HDRP update, but I have no idea when that will be.

If only But yes I am waiting so that this type of issue is kept at the absolute minimum.

 

I'm using the HDRP pipeline, it's amazingly stable and looks amazing.
When I try to use EyeAdvanced in the HDRP demo scene (Unity 2018.2.0f2), the material gets purple.
I'm not sure what goes wrong here. Textures all look fine, I guess it's something internal?

Can you provide a fix?

 

@OfficialHermie Please read one post above, as I've already stated my policy on HDRP. It will eventually support HDRP, but not soon. Those using LWRP and HDRP need to understand that these features are still in Preview mode and use them at their own risk. (such as shaders / assets not working properly).

Absolutely loving this asset! Brought a lot of life into my characters!

I got to thinking. Is there a way to have the eye shadows not actually move with the eye? Like, for example if your character looks down, the shadows move with the eye, and what you can still see of the iris is mostly shadowed.

 

Hi @BoxxyBrown glad to hear you're enjoying the eyes!
There isn't currently a way to keep the eyeadvanced shading from rotating from within the shader itself, since everything is rendered in one pass on the same object.

However you can get around this by duplicating the eyes and and using the shading texture on a new material on top of the EyeAdvanced eyes. Like so...



To get the above I did the following...

1. Duplicated the left and right eyes, and enlarged them to 1.1X the size as the original objects.
2. Made a new Standard material for the new shading objects and set the mode to Fade.
3. Edited the EyeAdvanced shading texture so the shading was in the alpha channel.
4. Applied the new texture in the Albedo material slot, then rotated each new object to best fit the head/eye shape.
5. Once I was happy with it all I separated the new objects from the original objects.

I'm attaching the custom texture below. You can follow the image for the material settings I used. This now lets me rotate the eye separate from the shading

 

That actually works really well and looks a lot better with my random eye movements! Thanks so much

 

does it support on HD Render Pipeline?

 

The Shader is not written for Unity's preview HDRP system. More info is available a few posts up.

 

Great!! Thanks!! Finally, all my beloved assets get ready for HDRP!!

Edit: DAMN!!!!!! I mis-read and I understood "The shader is NOW rewritten..."

You should really do this now as most other "pro" assets have already done that.

 

HDRP is still in preview. Expecting publishers to chase preview/beta stuff for free isn't reasonable.

 

@MrG Yes, but many asset publishers already do it anyways.

 

Also, @chingwa is the master of eye shading.
And since HDRP Shaders will also work for eyes (I haven't investigated yet in which way), he might contribute to the HDRP shaders with his knowlege.

 

I just received an email about how dilation works in Eye Advanced, and thought I would share an example here. Dilation can be controlled on the shader itself using the Pupil Dilation setting or accessing it directly through code via the "_pupilSize" shader parameter. Also, there is an example component that performs auto-dilation depending on the amount of light the eye is receiving.

 

Sorry for the offtopic, but dang, may I know what skin shader did you use for this?

Its brilliant!

 

@Stormy102 sourced the images from this presentation....
https://www.gdcvault.com/play/1018270/Next-Generation-Character

There's a PDF available of the presentation somewhere... it's worth a read through.

 

Aha I wish I had that skin shader - it was from the images in the presentation I'm afraid

 

Anxiously awating the HDRP update

You can already get decent looking skin in Unity , you just have to learn how to use its power

 

I don't really want to switch to HDRP at this stage tho

 

I know, I was on the edge too but after seeing the Heretic demo there were no second thoughts.
Not regretting it one second except for losing access to EYE ADVANCED for the moment.

 

Any HDRP releases will be in addition to the standard unity rendering, at least for the forseeable future. Though eventually I assume Unity will deprecate the standard rendering and focuse exclusively on their render pipelines. Probably still have a couple years before that happens.

 

Yeah I think it looks really good but the graphics we have at the moment are pretty good - its not worth the time needed to transition and learn at this stage... maybe soon

As long as you can offer Eye Advanced in HDRP I'll be happy

 

I have no doubt chingwa will do so once HDRP is production-ready!
