[Blender 3.1] Eye Rig SLOW AND HARD tutorial (30 minutes)(geometry nodes)

[@griseldaflores6362]

I am a god damn dumb *** lmao, I forgot to apply transform after rotating the sphere 90 degrees over X in the beginning

[@RadarLeon]

..... ah fack I did that too

[@jessicablunt7719]

Thank you for pointing that out. I was almost about to give up.

[@phillparkinson4671]

OMG thank you!!!! - ffs lol 🤦‍♂

[@rudypieplenbosch6752]

I never liked the other eye tutorials since they were all missing something and basically were too simplistic, this one is pretty perfect. I will make me a set of eyes as an asset, thanks man you have great tutorials, I have used several of them already for a small hobby project.

[@guohengchin]

This is hands-down the best eye tutorial for Blender I've come across, for the incredibly realistic result and more importantly the ease of customizing the components of the eye. I am still in awe that I can use this single eye setup for ANY kind of characters--humans, cats, catgirls. 😸 Also, thanks for breaking down the math behind the setup. It helps a lot.

[@sherzoderkinov4498]

6:48 - Those who are not getting correct deform of mesh, Try to change Cross Product -Y values from -1 to positive 1 (there are two of them you need to change) Edit: Select all and rotate -z 180.

[@90bubbel60]

when you mean select all, you just mean the entire sphere?

You are a wonderful person. Before you, I had seen many tutorials to learn geometry nodes, in which most of them just present their work instead of learning the process, but you talk about geometry nodes deeply and meticulously.

[@darshjoshi1641]

By far one of the best Tutorials I have watched with great results and proper explanation for decision making. Thanks! keep them coming

[@bluemosquedesign]

Incredible tutorial. I really appreciate that you share the thinking and reasoning behind why you are using the various nodes. Thank you!

[@gordonbrinkmann]

Great tutorial, the only thing that's bothering in your result is the strong refraction of the cornea. Because you just use a sphere the IOR makes it refract like a solid ball of glass, while in reality it's a kind of transparent skin which has a thickness to it. It's the same as if you're modeling a bottle or a drinking glass - without a solidify modifier or actual mesh thickness it looks like a solid block of glass.

[@IWDSoon]

this is geo nodes

[@MaxEdge420]

I simply didn't bother adjusting the IOR, since I wanted to focus more on the rig. The cornea has a 1.380 IOR, while the Aqueous Humor underneath has 1.330. If the cornea had a solidify modifier, it would mean the Aqueous Humor will have an IOR of 1. You'd actually get closer to a physically accurate result if you use an average IOR of 1.350 and no solidify modifier. Additionally, in this video I only showed Eevee, which uses screen space refractions, which are not physically accurate.

[@cyrotek3518]

I love this. I have no idea what the heck is happening but I just can watch it all day.

[@pitched7401]

Thanks for putting the files in the decription. Awesome tutorial as always. Your Videos show this kind of professional stuff you aren't taught by casual tutorials

[@strugglingengineer1465]

6:00 why not use the norm of the cross product that you already calculated to get the sin and then arcsin it to get the angle? 20:00 why not use the islands and the several other similar selections nodes in geonodes combined with the 'Set Material' Node without having to go in edit mode and select and assign? 23:40 Shouldn't the distance node suffice with the distance from vector (0.5, 0.5, 0) i.e. the centre of the UV map? 27:36 what I think about it? Amazing is an understatement! Excellent work! Subscribed! The eye itself matters less than the plethora of gold nuggets of geonodes techniques you've shown on the way! That being said... if it's not already done, it will be nice to see how you'd make the textures procedurally as well in shading nodes. Thanks a lot!

[@Osterprods]

Thank you very much, I managed to do it following step by step being a newbie to blender and without knowing much English, very well explained, working in the current version

[@Derny.]

the best blender geometry nodes channel!

[@Derny.]

@Captain Reason i had the same experience. it was mostly coincidence. i was searching for a blender snow tutorial. and few hours later I got his "geometry nodes - creating snow" video recommended. i saw the other things he did and I subscribed

[@Mryeo5354]

Agreed he's so detailed

[@M4rt1nX]

I'm in awe cause you always have absolute control of everything and know exactly what you are doing.

Today I learned more useful math from a fox than I did in my last few years of school.

[@phuquoc7918]

You are really pumping out content lately huh. I hope the algorithm picks this channel up.

[@vanished001]

If at 6:48 it doesn't look like that. Its because you're working in +Y not -Y. Change the Cross Product and Dot Product Y values to 1 not -1.

[@Lluc3D]

But you just release a tutorial man! un-stopable !! great work :)

[@neogmz]

This is so incredibly awesome. I just finished the tutorial as an intermediate Blender artist and I learned a lot of things. Thank you so much!! Also, since you didn't mention it, is it possible to set a control for the color of the iris? As to not having to go into the texture every time to alter it

[@edyzartz]

Love this! Thank you so much, the fact that i can control a lot of the parameters of the eye within geonodes is amazing, really helpful for me! I like making a lot of monsters or goo with eyes!

Hey @MaxEdge, man your work is truly inspiring...! Keep it up

[@Bwsab]

Helped me a lot! Thanks!

[@mhollis1989]

IDK what is wrong. For the Cross and Dot Product Nodes, I can only get my mesh to follow yours by substituting -1 for +1. This works until it is time for the cornea, which juts backwards.

[@vanished001]

All the map range values need to be on the negative axis. At 16:14 time stamp it should be -0.730, -1.000, -0.140

[@renato2987]

Did you apply transforms? The sphere needs to have exactly 1 meter in all dimensions. When he types -1 in y axis it means that it is the coordinate the Cross Product will use to create the X axis.

[@ScottRuggels]

I found one problem with the eyeball, unfortunately. When using AutoRigPro, when the eyeball is scaled down and the scale location and rotation is reset, applying the bind modifier causes the eyball to explode, separating the parts, and using the controls causes weird effects. I will probably have to go to a more traditionally constructed eyeball for the current project. Otherwise it's a great eyeball, for certain projects.

[@alexandermoyle9034]

Great tutorial and result! :D I found you can use CG Cookies eyeball textuing set up in combination with this to make the veins and iris procedural too :) thank you for this 🌻

[@nightwintertooth9502]

A feline has made your eyes even more complicated than your initial project with material custom properties for the Iris, Iris Emmission Glow, Pupil, and I added a bloodshot veins layer and ability to tint the surface of the eye, too, as well as made the entire texture procedural with noise layering and RGB masking gradients for some very dynamic, very cool renders of the eye. Thank you for giving the base for free, its been very useful to make very customizable eyes and extend from to make it even more complex with much more configurable options. I also made NodeGraph pass through form Object properties so you can adjust them all from the object tab. If you want the improved project, contact me as it has had a few days of work pumped into it to make it even more customizable, I won't sell or distribute it public it since it started as your work.

[@catchingsky334]

Why not make a follow up tutorial and reference this one as the start point for everyone to follow and drive traffic to this one too :-) Plus we get to see your modifications too :-)

[@Haarthainy]

Hello, I just made my second eyeball following your tutorial here and for some reason both of them did not turn out like yours. I followed as closely as I could and encountered different problems for both eyeballs I made. First eyeball no longer responds to most of the Group Input controls made from the Geometry Nodes while the second eyeball is missing its Iris entirely from view and deformed? Following your tutorial felt very good at first but then I guess something happened midway during the Geometry Node setup itself on both tries. Would like some assistance to find out I am missing but I will still sub and give a like here anyway! =)

[@vincivamos2118]

Hey thanks for the great video, I was wondering where did you get the eye textures from? I was thinking of maybe building a model on top of this one for generation of data for medical applications. Cheers to you and your great work with this one :)

Amazing, thank you! :-) fiddeling around with eyes for years...

[@grimcatnip]

i'm curious if it can pull off an anime effect or other weird effects. Like Heart or Star pupils. Or create strange effects on the iris. Like maybe its green but there's a spot at the bottom that is orange. This gonna be fun to play with.

[@JedahVulture85]

Pretty sure it can be done. This tutorial, while it's about shader nodes and not geometry can give you some ideas on how to do it: kzbin.info/www/bejne/i6fGY4NvZpalkM0 I'm just learning to do these stuff, it's amazing and MaxEdge is one of the bests!

[@KDawg5000]

I finished! I will reply here w/a link to my results. One thing I changed was the names "pupil size" and "iris size", since how it was done in the video, the iris size actually controls the pupil size. Oh, and I also made the bump on my iris negative. It just looked better.

[@KDawg5000]

Here's the result. I'm going to work on the animation and try to mimic the saccade motion of eyes. kzbin.info/www/bejne/nancc5Siipd_Z9E

[@parkeryates9570]

I love it, thank you so much for this tutorial.

[@LEEOSWALD69]

If anyone is having a problem where the image texture is not getting well scaled or just not right I've solved this by putting a mapping node to the left of the image texture node --> connect the mapping vector output to the image texture vector input --> Put a texture coordinate node to the left of the mapping node and connecting the generated texture coordinate to the vector in mapping.

[@pZq_]

Great tutorial. One follow-up upgrade of the eyeball would be reptile type with narrow pupil. Thx!

[@wevster]

This is awesome, thank you so much for this tutorial :)

[@Cuteathon]

This is brilliant. Will the download in your store work for v4? Also, do you have one for an oval eye?

[@stefvoogt5420]

Hi there! Amazing video, was following along perfectly, until I turned on Screen space reflections and refractions in the Eevee settings.. and now I don't see the Red of the Iris material? Everything else looks the same, but the red iris is not showing up.. it's not set to be transparent or anyting; any tips? 19:20 What I have right now is a white eye with a hole in it, and the transparent cornea around the eye. I'm getting the feeling I only need to select the 'outside' faces when creating the white Sclera material, but how do I do that?

[@benjacob416]

Had the same issue. When in the settings for the cornea material scroll down to settings tab and check the box for Raytrace refraction and Subsurface Translucency. This should fix your issue

[@Blackice350]

[SOLVED] Doesn't work right anymore in Blender 4.1. I can open the original file just fine, but importing as an asset result in a glass sphere. I tried to assign materials by hand, but The iris can't be seen through the glass material somehow.

[@elliotmarks06]

@@unicornhuntercg Yeah, but it was not meant to look the most professional. It was just meant to look cool, and for that purpose, it totally did! I can see myself using both of these in the future, one for more casual project, and this one for more professional scenes.

[@lv2draw1]

Was following the tutorial without realising I needed the beta version of blender until i got to 7:35. so was like "wheres the edge neighbours node?!" My bad - didn't notice it was a 3.1 not 3.0 tutorial, although if you have advice for how to go on without the 3.1 specific nodes it'd be welcome. If not, no worries i'lll just have to remember to come back to it in march

[@tuxgirl]

This may be a stupid question, but... At 14:46-ish, why do we only need to add the mesh island blocking to the first set position selection, and not the second one? It seems like we *ought* to be doing both, because we don't want either of the set positions to affect the cornea. I ended up adding it to both, because that felt more correct, but I'm not understanding why the second one doesn't seem to be needed (nor does it appear to change anything).

[@gehteuchnichtsan2436]

Verry nice also the download avcailable works perfectly fin. I have just one issues rendering the eye useless to add to projects. it brakes on resicing. Well i guess i could crowl through the geometry jungle and change any vector some how but i may hope you have a smart solution somewhere? I tried to apply the Geometrie node and evben then the eye Brakes apart up on resizing. special after load it in as asset libery content. Blender version 3.6 LTE

Great video, however, you only made one eye! most people have two. I tried duplicating the, second, but they both don't share the same controls. How would I make two and have them work together off the same controls? The one works great and looks great, thanks.

[@Toxicacidfire]

In case you didn't figure this out, the solution I implemented for this same objective was simply to add a driver to each of the modifier geometry node values on the duplicate eyeball. Set each driver to 'single property' > Set 'prop' to 'Eye.L.001' or whatever you have named your initial eyeball > Set 'path' to the path of the corresponding value on the initial eyeball modifier > Set 'expression' to var (not 'var + 0.173' for example). Now when changing a value on the initial eyeball, the corresponding value on the duplicate eyeball will change as well.

[@jrs7052]
