Not long ago I badly needed to reset the origin of my instances (letters) to create words with letters that scaled randomly along the word direction (not upwards) while preserving the kerning. I might finally be able to do that in a fast and nondestrucitve way! You are simply the best!

People who complain about long form content need their lazy heads read. At 7:00 I learned about Alt S for swapping 2 inputs on a node. What a magic shortcut for removing all my stress when dealing with massive node trees and their spiderweb of noodles. Thank you Erin. I am gonna watch the rest and take down notes and learn and, am also going to limit myself to just this one comment. Have an awesome weekend!

Following Up. Appreciate this app. Is there a way to get the Erindale Toolkit to work in the latest release Version 4.1.1? I recognize that both V4.1 Nodes Types and rendering methods have progressed a great deal since you created this add-on. I can till load the EKT Toolkit and it appears in the V4.1.1 shader editor but the final node types show up light gray and unselect-able.
@Erindale 2 ай бұрын
Huh that’s unexpected. It all works fine for me even in 4.2. Maybe just fully uninstall it, download the latest version from wherever you purchased it and install again

This is amazing. I am using this to create a structural mezzanine. I use your geo node to work with beams following the edges of a grid. How would you do to have a gap between the meshes?. I have a column on every edge, I would like to offset that so it appears that the beams are connecting to the column faces (instead of having them overlapping at the vertices)
@Erindale 2 ай бұрын
You could adjust the bounding box values of the beam when sampling them onto the points. If you just subtract from the min and add to the max in the axis you’re needed to extend then you’ll essentially create a buffer on both ends.

hey! thank you so much for the tutorial, its insanely helpful, but i got super stuck on the scale part, for some reason it keeps being zero so the instances disappear when i connect the divide edge length and instance length node to scale instances scale socket :(
@Erindale 2 ай бұрын
If you check your points, is v0 and v1 showing in the spreadsheet? What about min and max? If it’s the bounding box data then go through and double check all your attributes are on the correct domain and double check the bounding box group

Great tutorial (as always) 😍 One small question: Can anyone explain to me when to use truncated and when to use floored modulo? The blender manual isn't really helping me here 😐
@Erindale 3 ай бұрын
Truncated means that it descends towards zero, floors means it descends towards negative infinity. The only difference is for values below 0. Make yourself a curve line in geo nodes going in the X axis. Then take the spline parameter factor and multiply it by 10 and subtract 5. The module this by some value like 2 and use this to offset the position in the Z axis. You’ll see the difference between the two functions.

Great tutorial! But I have a problem, I did the exact same steps and when I divide the edge length to the instance length and plug it in the scale it simply returns everything 0, which means nothing appears, and i'm not sure why! Is it because I'm using blender 4.0 instead of 4.1 like you used?
@Erindale 3 ай бұрын
If you inspect the values with a viewer node on the correct domain, does the spreadsheet show the right values? It’s probably that something isn’t set to the right domain so you’re getting either 0 length or 0 size. Check your domains on all the sample and store nodes

@daniellord-vera6987 check all the domains on every store and sample node in the graph. Make sure that the data is getting to where it needs to be. Is V0/v1/min/max definitely visible on the instances in the spreadsheet?

@Erindale 3 ай бұрын
@daniellord-vera6987 my guess would be that something inside the bounding box or sample has an incorrect domain. One thing I did when planning was accidentally have the store nodes on the points set to the edge domain instead of points as I had copied them from v0 v1 store nodes.

There are lot of simple vector subtraction operations in this one, how subtracting a vector from other and reversing the order result in same vector with apposite sense, the illustration of this (just explaining using annotation) was missing, if done would have made bit easy for everyone even a beginner in math. anyways i got a bit digressed question on the current situation of cg industry, what you think how AI will shape the 3d industry in general and how unique aspects of blender like geom nodes, simulation nodes will hold its relevance in this ai led 3d world?

I’m not a mathematician so to me it’s just intuitive I’m not sure how to explain that any more than someone can just pick some numbers and try it for themselves. If I walk from the kitchen to the living room, I’ll go the opposite direction than from the living room to the kitchen. The world won’t be AI led any time soon. Investors are going crazy and CEOs are seeing dollar signs but when it comes to actual production of things that need curation and control, we’re a way off yet. When it comes, it will be straight to the final image we consume. 3D might be used just for massing and position consistency between frames but that’s being generous. There will be vastly less space in the world for human artists and those who thrive will either be technical artists or fine artists. Your average 3D generalist isn’t long for the world

@Erindale Unfortunately, there is no “Diameter” in the blender, I think you can create a “diameter” through geonodes. If anything, you can do a lesson on “diameter”. I'll be happy)
@Erindale 3 ай бұрын
If you’re wanting to define an explicit diameter then you’ll need to set it just the same as we do length. “Diameter / (max.x - min.x)” and the same for Y and use these for the scale of those axis
