If anyone is having trouble getting a material on the final geometry - In geometry nodes, add a “set material” node right before the group output. If it has the material assigned there it should work as intended.
Oh - thank you for that!
THANK YOU !
Real MVP status right here!
You are a life saver! Thank you soooo MUCH!!!
thank you very much! i was pretty confused n frustrated for a good five minutes there lol
feel like this would be insanely good for something like a giants causeway effect, again smashing it with these tutorials!

I have seen at least 5 hex grid geo node videos in the last 2 months alone and they all gone over my head at some point. This was great! Thanks!
+1 sub
I love it when people skip on something you have to look at their mouse to see what they've changed :D Good tutorial BTW! Thanks :)
Subbed and liked :)
Holy Moly, you are good in Blender.
Also its amazing how much Blender has grown!
Man , just wanna say you really have a talent to make everything look good in blender
Amazing tutorial and straight to the point. Earned my sub and like
this is so cool i'm glad southern shotty recommended your channel
In Blender 4, the random scale is operating on a group of instances therefore each line or two scale the same amount.
This is excellent!! Love a simple and straight forward tutorial! After following along, I found that you can replace the "Wrap" + "Greater Than" nodes with one "Ping Pong" math node (although, whether that is easier to explain, or understand, compared to the other nodes is up for debate).
even more shorter is to just use a Modulo node with a value of 2.
in the end tho, they all work since the three functions only differ with how they treat decimal values but the Index field only contains integers so you never get to see the difference anyway
I should have done that. It would have been so much simpler.
You could also use a grid. Plug it into a "mesh to points" - set to vertices - and also into another one set to faces. If you now join all the points, you get the classic honeycomb array for your hexagons 🙂
how do you mean?
Unfortunately that doesn’t work. The grid only gives square spacing and won’t provide the precise offset required for hexagonal profiles. You could use maths and more complex maths to set the position every row but that becomes overly complex. I recently used that method to offset rows on a brick wall and it was a pain.
You can use a modulo node (second value: 2) instead of the wrap-greater than combo, it's probably cleaner.
Thank you very much for the tutorial, very useful. I would create a cylinder inside the geometry nodes and put a realize instance at the end to be able to convert the geometry nodes to mesh.
simple and great!! thanks!
I watched this video, and had a lot of trouble with GeometryNode. Then I learned the Python functions I needed, and did part of it that way, although I haven't textured them yet. I think it's like dyslexia in the sense that some people need something visual, while some of us need something text based. I'm just glad that the Blender Foundation have created systems for both groups.
Great tutorial...very useful!
AMAZING! , Thank you!
this is really coolll! thank you
I have looked on your Gumroad page, truly inspired work! BTW Curtis Holt sent me!
same
I would love a description of what you're pressing to quickly switch your cursor to highlight a group of nodes, then adding/applying a frame at 3:08-3:15. I'm always looking for ways to keep the momentum going.
Also thank you, this effect is something I was looking all around for and this was the best explanation of how to get it!
Press B and select which nodes you want to frame. Then press Crtl + J to frame them. Can then press N to open side panel to edit frame
Dude made my day
I’m new to blender and was curious if there’s a way to get each hexagon to a specific depth instead of all a random depth. Any advice would help!
Thanks for sharing!
Nice job
牛皮呀👍学习了💯
A great 'to-the-point' tutorial. 2:20 I was able to replace the WRAP & GREATER THAN nodes with MODULO Value 2.000 (also a MATH node)
that is not a tutorial video lmfao
@@cqrhqr3418 ?
Yeah, saw the modulo pop up and wondered who'd comment that wrap was basically a modulo.
@@cqrhqr3418 take a look at 4:50 he said " thanks for watching this tutorial" lmao
Blender 4.2 now replace Wrap with Math node, Floored Modulo, value 2.0
very cool!!
Thank you!
Cool stuff. Noting that 0.866 is sqrt(3)/2 - I like to add it as a driver, i.e. #sqrt(3)/2), so I can see the expression later if I need to, rather than just using the decimal, but that's just me.
Also cos (pi/6) (radians), the same.
More than that, if the big side of the hexagon is
a = 2*R,
then the little side is b = 2*R*cos (30°) = 2*R*cos (pi/6) or 2*R*sqrt(3)/2 = R*sqrt(3)
That's not just you ;) Since I know that the hexagon is made of 6 equilateral triangles with a side length of let's say r (the radius of the circumscribed circle which was the radius of the cylinder used to create it), I know that the height of the triangle is sqrt(3)/2 * r. I also know that the "center left" vertex is exactly 1.5 times the radius away from the "bottom right" vertex. So no matter how large I scale the hexagon I always know I have to move the duplicate 1.5 * r times horizontal and sqrt(3)/2 * r times vertical. To know the factors rather than the absolute decimals comes in quite handy if you want to create the hexagonal grid inside Geometry Nodes with Mesh Primitive to keep the size variable or if you want to create a hexagonal grid with an Array modifier.
I tried adding your driver to the Y value, it just comes up zero, so I had to just use the decimal.
@@the_greck there's a trailing ) in the comment - this is a typo. Entering #sqrt(3)/2 in a new value should work.
What version of Blender is this? I only ask because it looks in every way different from the version I am running (2.8.2a), so much so that I could not even figure out what you were doing in this video.
Hi mate! Please if you can make a video similar to this but add how you can replace the random colors with a text and how can you make it look exactly like a honeycomb? Thank you!
so cool
thank you!
Thanks !
Dang, never used Goe Nodes before but this might have saved my ass!
Awesome tutorial. It's crazy how much we can do with geometry nodes but that's pretty non intuitive haha
All done upto Materials ...but material does not show up in Rendered view. What could I be doing wrong?
could i know what background light used?? its so pretty
@Bbbn19 Can you explain why the hexegon grid created with the nodes disappears when I apply it? Also can this be "converted" to something that will export for use in another platform such as Unity. Thanks for a great video. I will defiantly be subscribing.
add a Realize Instances node before applying the modifier -- this works with most geometry-node setups if you simply want the geometry for downstream applications
so good !!!!!!!!well ，can you make more complicated tutorial occasionally ？ like 20 mins long?
Sir allow me a quick question: i want to have the scale influce by empty sphere object, so everytime i move the empty on x,y, axies the hexagons will pop up/ disapear, with a littlebit falloff so the neighboors are smooth reacting same way. i tried add an empty object into this construction in combination with this random value, but i failed. it seems quit easy but im so stupid. can you please help me this short ?? the random value works fine, but i want to have influence by object, so i can have like a transition every time o move the object the hexagon disapears and so on. yeahh. have a nice day sir thanks for spending so much time ! really great artist
what if you want to color in a specific straight line?
Hi is there any merge vertices option in geometry nodes
How to make the nodes, if we use multiple materials?
Do you have beginner friendly tutorials? Like, what is the panel to the left of the viewport 20 seconds in?
I need a tutorial explaining how you found and understood the magic numbers you used?
the GOAT !
Now how would one put that on a sphere?
Awesome tutorial, but I don't understand what you click when you add frame on minute 3.10, can you help me please. Thanks.
Select the nodes you want to add to the frame than move them with G over the frame and click there.
Nice!, and how can I make a hexagon grill?
Your tutorial is very easy to follow. I get stuck at one point after setting the Frames and getting up to the point of launching the Shade editor. I do not get the Viewer to open up. I have tried adding Object info and I have ADDON: Node Wrangker on but I am still not seeing the viewer. Any help would be excellent. I also added "set material" right before group output.
Hi, not sure if you already solve the problem. If you did not solve it but still need an answer, all you need to do is Shift + Ctrl + LMB on the "Object Info" 😄
@@hmongstermoua1374 I'm trying to solve the same problem , but when I do as you say it just connects Object Info node to the Material Output node. Still don't know how to get the Veiwer.
@@hmongstermoua1374 hey sorry same problem but still can't get to the Viewer, I have Wrangler on and i tried as you suggested. I have blender 3.5. :)
Thanks for the tutorial! A quick question: how can I add transparency to the hexagons? I have tried setting alpha values < 1 in principal node, but it does not work :S
Could you try to add a "Glass Shader", I'm pretty sure that will make it transparent.
Is it possible to manually extrude individual hexagons once you make the grid? I'm trying to design something in which I need custom placed hexagons which are touching, so I would like to be able to selectively delete hexagons which I dont need and then extrude them upwards.
Add a Realize Instances nodes at the end of your Geo Node tree, then simply apply the Geo Node modifier.
What calculation did you do to get to the "0.866" magic number?
0.866 is sqrt(3)/2, or sin(60°)... Something to do with the proportions of an equilateral hexagon...
Everything's good but why bother with a plane, GN and a mesh primitive to make a cylinder and then apply the geo? Why not just make a cylinder?
Is this project file available by chance?
why not doing the hex and the mesh line in the same node? you already have the mesh primitives in the nodes
Because there is no bevel in geo nodes yet, so that needs to be applied to the lone hexagon, to be used in the grid version. If the bevel wasnt needed you could totally do it how you suggested.
Is there a specific reason not to use the modulo(2)?
To be honest, I forgot it was an option.
Basically anyone on a Mac that comes with an AMD card can't use Cycle because support for amd gpu start from 3.1 same problem wit HIP under windows :(
I did exactly the same on blnder 3.6. And it doesn't work. Can you explain why please ? :)
I can't find the viewer node. I can't explain the shortcut you used for it :)
dude you should tell (or write it in the video) where the hell are these fricking option because i can't get to it. I'm struggling finding "mesh primitives" and "mesh line" because my workspace is different from yours. I'm a new to 3d and blender
how did you get the 0.866 offset?
It comes from sqrt(3)/2, which is the distance from a hex center to its vertices
I tried applying to both the Plane and individual Hexagon too...but material simply does not show up. Could you post the Node set up or I could send the blend across to check?
In geometry nodes, add a “set material” node right before the group output. If it has the material assigned there it should work as intended.
@@RTKdarling WHERE DO I CONNECT IT
@@kelicarich4rd you can slide the set material node in right before the output. It's been a little while and I'm replying without the project open in front of me
you might also check if the use node is unchecked. it's in the top left of the shader editor.
Where do the numbers come from, .866 for example?
It comes from sqrt(3)/2, which is the distance from a hex center to its vertices
I have no set position nod? @ 1:38 using Blender 4.0
Ok so I can't search for this node for some reason. I found it manually, and then It shows up when i search. (shrug)
- +add node
- geometry
- write
- set position
also if you right click and add a node that way, It has a different search menu.
you have to do shift A for the correct search menu to show up. that had it in it.
how did the get the viewer node at 4:10 ?
Shift-Ctrl-Click on the object info node
:D
After watching this, I remembered Chernobyl's reactor floor where they start to move. wondering that would look cool with this hexagonal pattern.
Waow, you've been at Chernobyl at that moment ?! 8P
Thanks for this short and interesting tutorial, important to show and understand a good use of the Index node.
@@SGUnity lol XD
My shading wasn't working why is that?
At 2:30, why do you use a vector math? I'm trying to understand it in depth but the difference between math and vector math here :)
Vector math edits 3 values at once (kinda like red, green, and blue in color data) while regular math edits only 1 value.
@@CartesianCaramel Right, makes sense. Thanks!
I need this file
I can't apply the material? just stays white.
Same here.
In geometry nodes, add a “set material” node right before the group output. If it has the material assigned there it should work as intended.

@@RTKdarling thanks!
i cant even figure out the first 15 seconds. my blender doesnt look like this and i cant get a cylinder?
I completely lost it in the Shadin Editor part . Maybe it's the software version? I could reproduce up to the object input thing, but then the viewer node didn't appear to me, and so on. My blender is 3.6. Can anyone help, pls? Tyvm
Install Node Wrangler
TY@@caste215 , im on it right now.
Well, didn't work. Idk what am i doing wrong or not doing. What happens at 04:02 when 4 options/shortcuts appear and the grid changes color? Is it a selection, a step or something else that i need to make?@@caste215 That's where i begin to fail. Thanks again, in advance. And if anyone else can also help, pls feel free to do so. :)
if i press apply on the Geometry modifier the whole thing disaprears
You need to add a Realize Instance node at the end of your geo node setup before applying the modifier
Is there a tutorial on how to add trees and objects to the hex grid at random?
Here is is, th-cam.com/video/EboNtLKn_m8/w-d-xo.html
Yeah, none of this worked in 4.0.2
bro why the f is the node thing so complicated!! damn it! the first part was great but then selecting every other hexagon part got real confusing to me
ok. in the end
This doesnt work on blender 4.0 and 3.6
Jaw drop
Great Toturial, but you keep skipping little things, i'm a bloody beginner and i had to search a little bit to fint "math" or "colorRamp" because i don't have these nodes on favorites or shortcuts. :)
... I should have figured out hexagon is just circle with six sides 🤦♂
I'm sure that this is a good tutorial but not for beginners. 20 seconds in am I am stuck trying to Geometry Nodes.
so much math. How can a beginner understand this?
if the intention is to teach that you don't know how to do it, it has gone a long way... do things very quickly for those who are starting with you not to do any of that!
How do I set distance between the hexagons?
im still watching but if you use a square root math node set to .75
you can get the perfect .866 (or much more precisely 0.86602540378)
i needed a hex grid and .866 just wasnt precise for me ;)
