[Tut] Circuitry Board - Blender Geometry Nodes 4.0

[@bradleyanimation120]

At 09:27, if you are having difficulty to reproduce straight lines. Between Sample Index and Append Points to Curve, Please add an "Evaluate on Domain", and set "Float" to "Vector" and "Point" to "Spline". Or if you don't know what to do, please patiently follow the tutorial to the end. Your problem will be automatically solved by 24:50

Thank you😃

[@Diemetic]

the workaround provided at 9:27 did not work for me at all. I will be trusting the process and hope it is somehow solved by 24:50. But all im seeing right now is a bunch of straight lines on my screen around the invisible 1x1 plane. Update: it was not fixed at 24:50 @bradleyanimation120 (using blender 4.1)

[@bradleyanimation120]

@@Diemetic I can confirm they are still working as expected. Make sure you're replicating the setup of 24:44 exactly.

@@bradleyanimation120 Thank you Bradley for the help! You're right it works

[@jefflhama]

Awesome results. I stopped with blender for almos a year, while learning houdini and now Im back because of work and geonodes feels like i have to be a mathematician mixed with a software engineer to use.

[@bradleyanimation120]

I would say no, since I am neither of these two.

[@Armitag3]

Thank you so much for this tutorial! So much of this makes absolutely no sense to me but with every one of these you create I understand a bit more. Thank you for sharing your knowledge.

Aula muito boa parabéns

Looks great, mate!

[@scottlee38]

Awesome Work!

[@benthompson7789]

Is there a way to apply this effect to a curved mesh, say a cylinder or something?

[@bradleyanimation120]

Either you directly emit particles and move particles along the surface using geometry proximity, or you can map the result on a plane go cylinder/other geometry using Sample UV. there can be many different ways to do so.

[@willking6423]

Can you integrate it into a plugin and sell it in the market?

Nice video

[@contento_top]

Hi! I have a problem at 3:23, my curves are pointing in one direction (x-direction). I can't find a solution so that the curves have opposite directions

[@bradleyanimation120]

it would be better if you can show your node tree in the discord server. for now I can only assume you didn't disable "Curve Points Preview" as I did right before the repeat zone.

[@contento_top]

@@bradleyanimation120 The problem was that when searching for node assets, I have two different locations (Group-Assets and Bradley GN Presets - Assets), nodes selected along the Bradley GN Presets - Assets path gave an error. This is in the video GN Preset Addon Installation Guide at 6:16

[@bradleyanimation120]

@@contento_top two different locations are completely expected as a known limitation of blender asset library system. Developers are still yet in proposing solutions to solve this issue, and I can't speed up the process. On the other hand, there's nothing wrong. Nodes from either location will be 100% the same and won't cause any issue.

[@b23productionhk29]

use a different normal node, had the same issue as well

[@bradleyanimation120]

@@b23productionhk29 not sure what you mean. Did you solve your problem? Do you still need help?

[@RoN43wwq]

great!!!!!!!!!!!!!!

If I want to put a circle at the starting point, bend point, and end point, where should I put it? Can you give me a hint? 😞

[@bradleyanimation120]

starting and end point can be done by "endpoint selection", in case of bending point you need to detect the rate of curve tangent change from one point to next point. If the dot-product is less than 1 it means they have curvatures where you can select to add points.

[@salutnmm]

Oh Solved it :) If anyone want this, just connect 'instance on points' with 'endpoint selection' behind Trim Curve Thanks a lot Bradley!

[@williamrogers4612]

Another way that worked for me was adding a join geometry before the set material and then adding an instance on points node and connecting it back to the repeat zone. Then putting an endpoint selection into then instance on points node allowed me to have pretty fine control of where I wanted the instance objects placed along the branching path.

[@postmodern_bot]

Hey, the append point to curve node is not showing on my list :/

[@bradleyanimation120]

you have other presets except append point to curve or you don't have anything after addon installation? it would be better if you can ask in the discord server.
