@@BlenderMadeEasy I have account (working on a course on solidworks software) but never use for learning purpose. I try other email id as well still doesn't work
I have a fix for the poles that are too close to the other poles. I wrote a node group that resamples the curve but takes active points into account to keep a point at every given/evaluated point. It is done by subdividing each segment individually based on its length. In this process you have to split the spline at each point first to get the spline length for each individual segment, than stitch it back together by converting it to a mesh and using the "merge by distance node". Then converting itback to a curve. Will upload the group soon.
i'm using Unreal engine and im new to blender, but this was the most insane tutorial i've come across in a long time, the skill and perfection in this video tutorial is out of the ordinary, you are a MASTER, thanks alot man, il sub for sure, keep up the good work!
Nice presentation. I think you can use the total fence length together with vertical pole spacing as an input to drive the pole placement. A little maths function will provide the distribution automatically. Love your systematic approach. Great job!
Great tuto, but I've hit a few snags: when I do the rotation of my chainlinks, the corners aren't rotated 90 degree, and they sit at an angle. It's visible through the poles The second snag: I've moved the original chainlink to the right, so the starting pole sit well at the end, but the ending pole doesn't, the fence goes beyond it? Edit: And I found a way to not have the smaller vertical poles close/into the main vertical poles! After instancing both types of poles, you need to connect the smaller ones into a delete geometry set to instance, just before joining them with everything. For the selection of this delete you'll need: To branch the two instancing each into its own realise instance, then feed each into a geometry proximity Do a Vector Math Subtract (main poles top, smaller poles bottom) Feed the math into a compare node, set to vector, element, equal. The B vector is at 0 and the epsilon is the distance from which it'll start to delete the smaller poles. If that's confusing, you can find a screenshot in my YT profile
Great tutorial!! I took this a little step further and used the Delete Geometry node to remove the very bottom horizontal pole. I thought maybe it is unnatural to have a horizontal pole along the ground :)
you can also use also: - [Add] 1 -> [Resample Curve] Count - add an [Endpoint Selection] node - plug Count -> [Endpoint Selection] Start Size - set [Endpoint Selection] End Size to 0 - plug [Endpoint Selection] Selection -> [Instance on Points] Selection and it'll always skip the index of the bottom bar
What you can do is transformer your curve into mesh, split edges, then transform it into curve again. Your poles should be spread out much better now. After that you can add delete geometry and plug endpoint selection into selection. This way you won't have two poles in the same place.
perhaps this is obvious but I tried to animate this "create instances on the fly" effect (and tied it to a sound-from-f-curve) it was cool in the viewport.. but these objects don't show up in the render unless you realize them. In which case they are no longer dynamic - so i will have to start over and probably animate their opacity based on the music and their position. great tutorial by the way - learned a lot as usual
Great tutorial. I successfully created my first geo nodes thingy. Used it for a different design and not fence. Is there a way to used 3d curves so that things can go up and down too?
Nicely done 👍 And by the way: Leonhard Euler was a famous Swiss mathematician who is pronounced „Lay-On-Heart Oiler“ 😉 So the node at 8:58 is called „align oiler to vector“.
You should be able to add a new object, assign a material to it and instance it as whatever you want it to be. This way you can have a different material for every different part of the fence
Yes you can - just add the 'Set Material' nod before the 'Join Geometry' instead of after, you can apply materials to each element separately this way.
Thank you so much for your hard work! 😊 I wanted to ask something unrelated: 🤔 I have these words 🤨. (behave today finger ski upon boy assault summer exhaust beauty stereo over). How do I use this? 🤨
Awesome! Thanks for making a geo node tutorial that's easy to understand :) PS: Is there a way to bevel/sub divide/smooth the vertical poles? There's stil no bevel node in geo-nodes.
Super video, it's simple but it's a good explaination on how the tool can do. If someone has an answer, I've got 2 issues: • even by taking the x measurement, the shape are not connected, there's a space between each repetition • the fence try to turn on corner but a part is hanging Anyone also go this issue (Blender 3.1) ?
I have the 1st issue as well. The main issue with it is after converting the result to a mesh (before export) it contains a lot more vertices, since they could be merged if they didn't have a space between them. If anyone knows the solution that would be great!
This tutorial is incredibly helpful when trying to learn this stuff! I just have some questions because I want to use square posts instead of round ones. How do I make the "Align Euler to vector" snap so that my corner posts aren't rotated 45 degrees and how can I lock middle posts to be a separate distance apart from each other?
I just tried building out this setup and it appears to work the same with square posts...which I tested with rectangular posts just to confirm their correct orientation. As for the second question, if you want to use different setups for end posts and middle posts, you can select the instance nodes setup and group them (so you can duplicate the setup and modify the duplicate), then use the endpoint selection node to select the points for the end posts and a boolean math node to select all the other points.
just kidding. Yes, if you use the "merge by distance", it desperatly won't work. But, if you use "Realize Instances", the "Merge by Distance" will accept to merge the splines, and then the curve to mesh will generate nice and smooth continuous chains.
hey so this tutorial is amazing, but I had a problem when I connected the chains, there is a small gap on the right side on each linked square thing, is there anyway to fix this?
Yeah that is one problem I noticed too. That's the issue with using the Length in the Resample Curve. If the Fence Line dimension length is anything BUT a multiple of the chain object length there will be a slight gap between each chain. 1 thing that you could try is to edit the last point on Fence Line object and move it just slightly back to line up all the chains. I had forgotten to mention that in the tutorial.
Not really sure how unreal engine works, but I'd try to apply the finished geo nodes to the starting object/curve so that you get a simple mesh. Exporting that should work.
Everything was going just great until you press "N" to enter "input" I do not seem to have that all I am seeing is nodes and the layout is quite different. Any suggestions?
I'm working the fence mesh and noticed that you have the mesh sideways. I keep seeing chain link fence tutorials with this flaw. Chain link fences are not built this way and you can't get realism because you wouldn't be able to add brackets and braces at the posts because you have your links sideways. The cut, sharp exposed ends face the ground, you couldn't add hardware with them facing sideways like yours. An installer uses a knuckle wrench to bend those jagged ends around. How would you do that with just the end column of geometry so hardware could be added in archvis? Just another point for archvis realism, the mesh runs outside the posts, not through them. That's where adding the hardware for bracing comes in and you discover the jagged ends won't let you add brackets, tensioners, fence hinges, etc. Not picking on you, this may be good for making game assets, but not archvis. Fences are seldom on level ground, they run up hills, down hills, over swells. If you try and move/add points on your reference line, it breaks apart the mesh if any point is not on the same level as the others. I have yet to see anyone come up with a realistic way of making chain link fence and I've spent countless hours trying. You could use a boolean to cut the fence but you first have to use the "realize instances" and that just defeats the purpose of an instance and jumps the face count up astronomically
just export it as FBX mesh. try apply the Geometry node Modifier - or in Export option you can choose " add modifier" - hope it will work. In UE4/5 just import FBX / or drag & drop it into your UE Folder when your project is open
you guys make it look too easy. I think the poles work as is - no changes needed - it's ok if some of the poles are near the bigger ones. Just need to keep that distance the same max spread (but not averaged) between the small poles within a particular line (which it already is) - just like 2x4 in house is always max distance of like 18" from another, but some 2x4 go right up close to edge, but aren't the edge itself, so spacing between them is minimal.

Could you do a tutorial for making a chrome material using nodes? Anyway, cool tutorial as usual!

Great tuto indeed. Unfortunately, same problems here.
Hey Felina. Thank you so much for your hard work here!
Thanks, was able to get the excess poles deleted thanks to you. Trying to figure out how to deal with the uneven rotation of the chainlinks next..
Great tutorial!!
I took this a little step further and used the Delete Geometry node to remove the very bottom horizontal pole. I thought maybe it is unnatural to have a horizontal pole along the ground :)
You mean "pole". Make it optional because our fence does have one! ;)
you can also use also:
- [Add] 1 -> [Resample Curve] Count
- add an [Endpoint Selection] node
- plug Count -> [Endpoint Selection] Start Size
- set [Endpoint Selection] End Size to 0
- plug [Endpoint Selection] Selection -> [Instance on Points] Selection
and it'll always skip the index of the bottom bar
What you can do is transformer your curve into mesh, split edges, then transform it into curve again.
Your poles should be spread out much better now.
After that you can add delete geometry and plug endpoint selection into selection. This way you won't have two poles in the same place.
