I’ve just revisited the Youtubers who created many cool procedural modeling videos in the past, but the videos are now all gone, the Youtubers have selectively deleted them, only procedural modeling videos.
What happened? Were Blender users on a movement or something?
Geometry nodes are in very active development and many new featres and changes are introduced with every new version of Blender. There are even plenty of videos about new features in Blender that appear in daily builds. Some videos might go out of date quite fast. …or it’s all a big conspiracy. Who knows…
Thank you for the reply.
Just a question, will Geometry Nodes’ Procedural Modeling ever replace Cycles Shader’s Procedural Modeling in the future? Can Geometry Nodes do everything that Cycles Shader does?
I think I will create another topic for this question in the next minutes.
What? You can’t model with shader nodes
No, they’re entirely different topics?
What? You can’t model with shader nodes
I’m not sure if I’m using the right name for these “things”.
This person (CGmatter) procedurally created a traffic cone using Cycles Shader nodes (or whatever it’s called, please suggest me a correct name).
I believe you’re referring to displacement with the “experimental” adaptive subdivisions…
Geometry nodes is waaaaaaaayyyy more powerful and can do that and so much more.
(Materials are still better with Material nodes though.)
Yeah well people used to do all kinds of crazy stuff like that with material nodes for fun and to show off. Material nodes don’t even compare to capability of geometry nodes now when we are talking about procedural modelling.
As you have not mentioned any specific tutorials, it would just be a shot in the dark for us to guess why some rando took down their video.
Sometimes people take down a video because the technique is no longer the best way to do it in blender. Or they might take it down because it didn’t get enough traffic, and they don’t want that to count against their YouTube algorithm hit results. It’s also possible that the video itself was a PR problem, due to comments or some other reason.
Hi!
Kris Bettini deleted their famous “RTX graphic card” procedural modeling using Cycles Shader Nodes video, which I believe to be the most complicated procedural modeling work I’ve ever seen.
InterPixel deleted their Voronoi’s Math explanation video and a bunch of procedural modeling videos.
Both of those people list ways to contact them, on their Youtube channel… so… ask them?
I don’t think you can really call shader node proceedural modelling “work”. I think it was done mostly for fun and to show off one’s skill. There are probably exceptions to this(I mean there must be… 
) and there might be some good use cases, but Geometry Nodes is a completely different thing. They are meant for proceedural modelling as opposed to a hack that is to use shader nodes for modelling. It is litterally a hack as shader nodes were never designed for this. If you liked what people used to do with shader nodes, you should definitely check some tutorials on Geometry Nodes and learn more about them.
The person who conducts the video is the person who creates a lecture about both the geometry node and the shader node.
And the image you showed me through the link was not actually modeled, but it was shading to create the shape using displacement.
You can only view it in renderings. 
About the displacement tutorial, that is probably more efficient to do a part of modeling with geometry nodes and keep rendering displacement for details.
About Voronoi’s Math explanation, Voronoi’s texture will change in Blender 4.0.
Hi, would you mind explaining how Blender’s Voronoi is gonna be changed?
I’ve watched the Voronoi video before, it derives and explains the intuition of Voronoi texture in general.
Is Blender’s Voronoi gonna have its internal code changed but the intuition stays the same, or are the developers going to create Voronoi 2.0?
Fractal noise was added. There are 3 additional sliders and an additional option to normalize Distance output.
Randomness slider passed from second position to last one.
https://wiki.blender.org/wiki/Reference/Release_Notes/4.0/Rendering#Texture_Nodes
The author of video could be annoyed about possible confusion, that could happen if wrong slider is tweaked.
Or maybe, he wants to update his video to talk about fractal noise.
Ah thank you.
I was afraid that they are going to throw away the original Voronoi and Noise lol, I spent many months studying the Math of both of those 2 textures.
I somehow missed that change. That’s very cool. It’s going to be awesome.
